Hey guys, Darion from the video here.
To answer some of your questions here are some explanations.
To the warm up procedure I use, you can do whatever youd like, this is simply what has worked best for me. If youve gone 160k miles on your renesis by letting it idle until it warms up every day then do that. These are my experiences combined with my knowledge of working on these cars over the past 5 years and owning one even longer.
The guage pod setup I have is a generic glow shift A pillar pod and I formed the pod to my A pillar with bondo and heat then sanded and spray painted black.
Yes I know this car doesnt necessarily "start right up" to someone who is familiat with these cars, BUT to Joe Blow whos never owned anything but a honda civic this could be "starting right up" to him even though its likely his engine is failing.
Some of the stuff I covered here is merely my experiences and some of it is straight up facts.
In an auto 6 speed after the re-map what is the highest rpm without hurting my rx8??
@@BaaZuu1688 you can safely go to 9k in terms of the engine, but keep it at 8500 for the transmissions sake.
Had an RX7 turbo 1988. I drove it real hard like it was intended. Every single morning, i waited about 2 minutes after the engine started. Maybe more. Car was bulletproof. Nothing went wrong with it in 5 years and 75K miles.
Good job keeping rx8's on the road
He’s talking about different oils based on the climate, sir, I live in St. Louis 😭. It’s supposed to be 25 today and 80 tmr 😭
Yo STL rotary gang.
Run 5w-40 bro
I just wanted to say as a long time RX driver and someone who really got involved in every last detail of the vehicle/engine - this is definitely one of the best "explanation" videos out there; I especially appreciated the side remarks. Good for you for taking the time to put it together and for doing what you do. I'm currently still living in Germany, but will be moving back stateside (also means currently selling my 06 rx - very sad), but I wouldn't be opposed to getting another one once I get over there - maybe we'll cross paths one day. Cheers
Hi Franz, I’m looking for a cared 06+ RX8, in Germany. If you still have yours, let’s get in touch if interested. Best Rex
Very great and informative video for RX8 newcomers! I will recommend this one if needed.
One side note only, in rx8 you do not really need to premix, as good dedicated Rotary garage can comleptly retune OMP Oil dosing in ECU, and set like 50% more Oil pressure also! That will help even better than a premix.
But anyways, great video as I said, cheers!
Wow I never heard so much professional information in one video
You've put a really great mileage on that
@Lochlan Lyle damn, does she drive an rx8 too?
@Grey Adan your gf runs rotary too? Damn it
One of the best detailed rotary explanations, thanks guys, 2 years after you made the video and I'm still searching for this info. The only thing I thought was missing - streetports, there are very controversial opinions about them and we would love to hear your take on it 😊 Cheers and thanks again!
Thanks for the info, much appreciated
I learned a lot, Thanks so much for the video.
good video man. really thought out and put together, i loved it. keep it up!!!
Great video! Thanks for sharing.
Thanks. We try.
Good knowledge, I scour the internet for info on the rx 8, this is better than most channels..
The best channel would tell you to get a better car...
Nice info. Thanks!
This was great, good info with good entertainmemt value
Did not know about how to see what kind of a starte you have looking at the rpm
I used to think I was being smart by letting the car idle to somewhat warm, but you just made me realize the low oil pressure at idle.... definitely giving u a like and a sub
ALWAYS LET YOUR RX-8 WARM UP! This was a great video but I STRONGLY disagree with his 30 second recommendation. Cold Start: Key on ( wait on beeps to finish) crank. Let it warm till temp gauge moves at minimum. i always wait till its 140 - 150 and then i go about my business.
Its pretty much however youd like to do it to be honest. Theres so many quality control issues with the renesis engine its hard to know what works and what doesnt.
Some guy might think hes done good by letting it idle until it warms up, generally speaking this puts less wear on the bearings in any conventional engine.
Ive gotten 160k miles now out of mine by starting it, letting it idle for 30 secs or so, then driving gently until the oil is warm.
It worked for me, it might work for you, it might also not work for you.
Matts comment might work for him, and it might also work for you. Its just one of the things I like to cover.
@@darionfarina2069 low oil pressure in a renesis is worse than a piston engine
@Darth Vader 5-8 psi is the spec at warm idle.
Being a rotary owner I enjoy stuff like this. Rotary’s are not hard to own. You have to love the hardships of owning a rotary. That’s the fun of it honestly. Owner of a 1989 Mazda rx7 fc gtus
Great video bro
Good vid y'all, i love the serious humour!😂
Does these recommendations apply to both Series 1/2, and S2 R3?
I live in the tropics with a 09 S2 R3, the temp never goes below 80f. so 20w50? or 10w40?
勉強になりました。thanks. This guy is smart and funny
Good talk class.
Which premix is good to use in Canada? And is stp complete any good to use every fuel up ?
Yo uso idemitsu rotary engine oil 10w30 creo que deberia ser un buen aceite apesar de ser sintetico.
I have an FC and the gauge actually moves around a lot depends on ambient temps, A/C on/off, stop-start traffic/cruising, and how hard I am driving the car.
I am from Australia and during a nice 20-24 degree day, the needle would stop around below 1/2 or at exact 1/2 way. On a hot 30-degree day with stop-start traffic with A/C on, the needle would move up to 3/4 of the gauge. Then If I was able to get the car on the move/cruise, then the needle would drop down to just over 1/2 gauge.
I am doing an AC system retrofit/upgrade with a bigger condenser. Also, a bigger radiator to compensate the extra heat from the AC system and getting the engine runs cooler.
From this video, it makes sense that the RX8's gauge is one of the major flaws that make the engine fail so much more than the RX7. Also please don't turbo because turbo = trouble. Great video 👍👍👍
Yeah the fc and fd are really well built. The rx8 kinda got pooped on cause of emission standards and shit.
i agree that non turbo is probably the way to go for rx8, but i think by using low boost and a small turbo + porting the exhaust ports. (alot of carbon tends to collect on the exhaust port. so porting can help keep it clean)
I have an 04. I changed all my hoaes, new coolant tank, mishimoto rad and fans. Will problem do new oil cooler lines when the engine does crap out and gets rebuild. Would you think I'd be good to turbo then or should I add fans to the oil coolers?
If you are trying to achieve 300-325 horsepower, then just do the turbo now, and transfer the system to a replacement engine when your compression gives out. You don’t need an oil cooler fan unless you restrict its airflow.
If you are trying to achieve 350+, then you should budget for a build and add the turbo at the same time for a bespoke build, instead of two things patched together.
What kind of gauges would you recommend in terms of upgrading from the stock one? Would me plugging in a OBD2 style gauge work just as fine? Also How come the thicker oils? is it just due to reducing wear on the housing?
I use an aftermarket set of glow shift guages with sending units, you can use a live data OBD2 guage as well that will give you the temps from the sending unit on the engine itself as well, but the RX-8 does not have an oil pressure, or oil temperature sending unit, so those two things will not be able to be monitored via OBD2. Thicker oil helps raise oil pressure as the series 1 renesis engine is notorious for bearing failure. So the increased oil thickness will help keep the bearings from failing and also thicker oil will wick around the housings against the seals better than thinner oil will, which provides added lubrication to the seals.
Keep it up! 👍🏻
There is an Australian rotary shop doing 14 pound psi on the standard RX8 motor.
I own an 04 RX eight and I was curious after knowing that the automatic is limited to 125 mph if you get it tuned could they remove the limit in the gearbox/computer?
Yes, with a tune you can override or change both the speed governer and the rev limiter
Mines also a automatic and been looking for a upgrade starter for mine but every year is the same unlike the manual cars, mines a 05 and the starters are all the same no matter what series it is. Where can I find 1 at?
they have a soft "power rool off" in 6th on manuals also. so the stock one is ECU limited as well, its not like a bmw with "hard stop" it is just power roll off.
My rx don't start but it was running good .gas light was on .I did had gas what u think is the problem. Last thing it did it was explosion on exhaust

What is the address of your workshop? I am in Houston and I want to talk to you about buying a RX.
Operating temperature has zero effect on wear of your engine. As long as you have oil pressure you are good, when it’s colder it will run richer, this is not going to hurt your engine
Depends where the sensor is fitted your aftermarket sensor is obviously outside of the thermostat circuit you would know that if you had a clue, the coolant that the stock sensor is reading is what is exposed to the housing seals.
People sure do get angry about warm up procedures. We appreciate your enthusiasm.
Let's not forget those trashy stock coils that fail constantly! That'll make for bad hot starts and lack a heck of a lot of hp.. On my second set now which is failing again so upgrading to the LS mod.
What are the wheel model on the RX8?
Do you have any recommendations for running Nitrous on a renesis or would you disregard it completely?
A 50 shot is about the furthest I’d go using nitrous, not really worth the money imo, you could make the same amount of power atw with a rebuild and a good tune.
The Renesis is fragile and extremely unreliable stock... if you need more power? Buy a real performance car.

Great information I own an RX8, it’s really hard to hear you with the music playing while your talking, I had same problem with my CZcams channel when I started, if you want to use music have it play very light in the background or use it only when it’s cinematic shots or time lapse videos.
I can hear him fine
Where did you get those side water temp gauges
GlowShift.com
Do you have a link to a upgraded starter that you’d recommend?
Look up the N3R3 starter(if it’s a manual), if it’s an auto you’re pretty much stuck with the N3Z1 starter or equivalent.
99.9% of starting problems are due to low compression....

Dont waste money on a bad engine.
I’ve always been under the impression I should let it sit and warm up 😥😥 I’ve bought an 04 , it had 107-114 psi across all faces but unfortunately I let it idle until operating temp before every drive , with that being said , it’s not a daily driver , maybe 2-3 times a week , no hot or cold start issues , how would I know if my stationary bearings are shot ?
Just look for metal in your oil, and oil filter. If you see copper, that's very bad.
You likely have nothing to worry about. Either way is a fine way of taking care of your engine. I just simply suggested my experiences with it(everyones experiences differ). If you like to warm up before driving then go ahead and do that, but its not going to hurt it either to drive gently until its at operating temp.
The one question I have is what can you do to make sure the car stays cool? Add another rad, change to a better performance rad? Change the Thermostat for one that opens at lower temperatures? I believe this is an important one, some might be easy to do and others might not be but it would be interesting to find out what the best for say "daily every day type driving and a more robust type - track use". Great video and keep going!
We’re making a video based on your question. We’ll have it uploaded within the week.
Another thing I did notice, even though you think your engine started right up, it took longer than mine
This is true. Compression as I mentioned is in the mid 70s, its at 194k miles and still going. It doesn't "start right up" compared to how it used to.
This was more to explain to people who may have just bought one and have no clue about anything about the car. To them, that kind of start would be "starting right up", though to us that are more experienced we can definitely tell the difference.
@@darionfarina2069 so is it hard owning and taking care of a rx8. I never had one I'm also wondering can I buy one that has 120 to 140k miles on it already? Also how many miles can I get out of the rx8 . I'm very interested in buying one it's just when I asked guys about them their response was oh they are rotary engines they garbage and saying once they reach 100k and up they need a swap or rebuild but it looks likes your is 190k which is encouraging to me cause it shows they can go up to 190k and still runs good all the horror stories I keep or kept hearing about how bad engines rotary engines where
@@Mrsilva94 they can go that far, but its not very common unless it has the right care. Its not hard to take care of just stay up on maintenance, and premix.
@@darionfarina2069 , so can I buy one like a 05-07 1st generation rx8 with like 120k to 130k Miles already on it ? And also how can I get it to be able to get up to the high miles then down the line get a newer engine. I dont beat on cars I drive back and forth to work which my job is like 15 minutes from my house . And I would regularly take it to get oil changes . I live in south Carolina its winter now it dont get like super cold but we have some cold days so how would I take care of it so it would last cause they look to dope
@@darionfarina2069 , your the only one up here who has information about the rx8 who answers me back . So ok can I buy a rx8 with 100k or over 100k miles on it of asking them how well they took care of the car . Also if I was gonna buy it contingent on how well it was taken care of will i have to do a engine swap or what . Help me understand how to take are of them.
what gauge pod is that?
Its a generic glow shift A pillar pod that I heated up and formed to the stock A pillar and painted black.
If I am always using premix at half an ounce per gallon, would it be ok to get rid of the oil metering pump?
We would recommend stepping it up to 1oz per gallon to be safe.
@@themotorlawcompany4673 ok, thank you. I'm thinking of getting one and making it really nice so I can show it and have it look nice for car meets and I would like to relocate and delete some stuff to make shaving the engine bay a little bit easier and nicer in the end
Premixing is monumentally stupid, it will only damage a healthy engine and does nothing to save an failed engine with low compression...
@@sandervanderkammen9230 you know nothing about the rx8. Premix is used in a two stroke engine to help with lubrication; think of a rotary as a really big two stroke. Another reason why premixing is important with the first gen rx8 because of how the injectors are setup. It sounds wierd but premixing is essential on the rx8, atleast the first gen, I'm not too sure about the second gen since the injection issue was fixed
@@brandonbennett7865 You sir are an uneducated imbecile.
Mazda does not recommend Premixing and there is no premix 2-stroke oil available that meets Mazda's minimum API SL specification.
People that are too ignorant to read there owners or service manual or read the label on a bottle of motor oil should not give advice that is directly contradictory to the manufacturers service and maintenance specifications.
Any questions son?
My engine just died last week, dies at idle and compression is around 4.8 at 250 rpm. Do you know any shops in Houston that can rebuild it?

@@themotorlawcompany4673 i’m in Asia and my compression is at 50 psi (cold start and normal operating engine temp) how can i fix this?
@@kzz8971 you can’t fix low compression once it’s down below 60psi.
You will need to rebuild your engine or replace it.
@@themotorlawcompany4673 If I rebuild it, what items should I buy to get more horsepower/reliabilty out of the engine?
@@kzz8971 it’s difficult to get more power out of the Renesis. Best route is turbo or do an all out conversion to a different engine like a 13B REW.
How have you come up with this info? Do you know that the key to a successful rotary reliability is correct warm up process.. 2500 rpm 4 mins ? story has it 1975 Bathurst 1000.a fella raced his Rx 2 and completed the race ..and that car was sold and went on to do another 100 000 miles finaly it was precautionary rebuilt .. story title was .. the key to success with this Rx 2 was correct warm up proceedure.. do you believe this Rx 2 got warmed up for only 3o seconds?
Wait what I get 18 mpg when drive under 4k all the time . How are you getting 23-24 i avg 13 lol
lol same
My miles at the time of this video are majority highway miles. Im not doing stop and go very often. I used to drive this car over 150 miles a day 6 days a week.
If premix more safety for the engine...
Maybe... Delete omp is the best effort... Isnt it?
Definitely keep the OMP.
It is likely to be one of the first things to fail or stop working properly in the long run. Premix is your insurance that even if the OMP fails, you’ll have sufficient lubrication.
Only time it makes sense to delete the OMP is with full fledged track-only race cars.
20w50 in hot climates?????
We got over 130,000 miles on an engine running it, so yes. In HOT climates, 20w-50 is OUR recommendation. Others disagree.

No it's a 1.3, the 4 rotor is a 2.6

There is so much mis-information in this video. Water temp doesn't rise at the same rate as oil temp. You don't nail your rotary until oil temp is up to operating temp. The oil temp can take a little longer than water temp. "In 2004 Synthetic oils were new" ... wtf? NO ... just no. How well does synthetic oil burn compared to mineral oil? the best option is to feed your OMP from a separate reservoir that is filled with 2T oil, and increase the rate of your OMP (more so with a S1 engine, due to it not having the extra oil injection).
Finally, someone who thumbed it down actually commented.
Thanks for your feedback. Too bad you and the other seven guys are so salty.
@@themotorlawcompany4673 Fck it ... I'll change it to a thumbs up. Only disagreeing with 3 points out of a 15min video isn't too bad when it comes to rotary discussions.
@@ImEasyAs it’s really aimed at brand new folks, tbh. Trying to keep it easily digestible.
Thanks for the support!
@@ImEasyAs you are absolutely correct, but in the RX-8 bone stock there’s no way to see oil temp or even watch oil pressure drop as the temp rises. Yes synthetic oils weren’t new in 2004 but my point was they were still early in development to as good as they are today. Back then it was actually proven that conventional oils will burn with less residue left behind than synthetic oils, which is a more in depth version of basically what I stated in this video. So letting the coolant get to operating temp before beating on it is better than beating on it dead cold, and synthetics in rotaries now are better tested and it is widely known that it can be used with no problems as previous synthetics 17 years ago were not.
@@ImEasyAs this video was simply aimed at newbies who probably have no idea how to even change their own oil, and gives them a dumbed down version of the knowledge that you and I both have that is easier to understand and easily digested for someone who is new and likely doesn’t understand much.
I know some guys make over 600hp rx8s
With the right modification, you can definitely break 600hp on a Renesis, but the 423hp unit Darion mentioned was on a stock block. No internal mods, or reinforcement.
@@themotorlawcompany4673 Yeah im not sure but TurblownEng on CZcams has made some powerful rx8s and if im not wrong there are some with over 500hp with stock internals.
@@JA-lg3tl Indeed. Nobody with experience really builds Renesis, as I’m sure you know.
It’s not ideal for a heavy hitter build.
I don’t have an example, but it can surely be done with enough money, special engineering, and special modification with the right fuel.
High emphasis on enough money. Probably would blow a few engines on the way, and the ultimate result would not likely be a durable unit anyway.
Wouldn’t think too hard on it. I don’t think anybody without super deep pockets would pursue it.
@@themotorlawcompany4673 really cool information for people who want it.

I think the limiting factor would be having to build a custom exhaust which would carry a high cost but i'm sure there's farther someone can go with it.

But first I need to buy the car lmfao
Makes more sense to buy a C5, doesn’t it?

1.3L engine lol thats were you really lost me
@TOYOTA Boyz Its not a 1.3 liter...
@TOYOTA Boyz Total displacement is actually 3.9 liters but when you directly compare the 13B to a reciprocating 4-stroke engine its more like 2.6 liters.
The 1.3 figure is what was called "tax displacement" an idea conjured up by NSU as a way to boost sales by reducing the cost of vehicle registration in countries that tax vehicles based on engine displacement.
Most countries now use the 2.6 liter figure.
@@sandervanderkammen9230 this is actually common misconception and myth, and is explained well vastly across the internet, the total combustion chamber displacement across both rotating rotors is 654cc, making total displacement 1308cc, making the engine a 1.3l engine.
You cannot compare the rotary to a piston engine in terms of displacement as the displacement is achieved differently, therefore comparing them is null and void.
Think whatever you’d like though, I’ve had this conversation with so many people it’s not even funny and they just refuse to believe what I’m saying.
@@darionfarina2069 Sorry but you are very confused and misinformed about calculating swept volume displacement of Internal combustion engines and the fundamental principles of the Wankel KKM engine design.
The Mazda 13b series has a total displacement of 3,924cc's
But when we compare Wankel engines to normal 4-stroke Otto engines we use the 2x conversation formula for 720° which gives us roughly 2.6 liters in effective displacement.
Any questions?
@@sandervanderkammen9230 the way you are measuring rotary engine displacement is more than flawed but you can think about it however it makes you sleep better at night.
Should I really listen to a guy driving *automatic* 😂
You're hilarious.
All of this and your car has low compression? Doesn't fill me with confidence
You should go against our advice then.
lmao a stock RX8 you legit can't get it to go faster than 154 and you have a lot of RPM's to go but it just will not go faster. It's abnoxious.
So...don't buy an Rx8. Got it.
Your warming up idea isn't true at all. You will put more wear on bearings by placing load on them when the oil isn't at optimum temp.
Looking forward to you posting a video explaining your expertise and alternative perspective, since out of 30,000 viewers, you are among a super tiny percent of people who seem to know better.
