Maybe if folks stopped putting in the cheapest garbage gas they can find into the vehicles. Make the vehicle premium fuel only. I like how people take what is probably the second largest investment they make in their life and leave it outside because the garage has some boxes of home interior crap they haven't looked at since 1988 in it. Then go out of their way to find the worst gas in town so they can save .05 per gallon or about $6.00 a month in savings. This is why we cant have nice things guys.. everyone should be having 13/1 compression minimum nowdays. The power, fuel economy, and cleaner burning engines are so close but because of savings of 2$ a fill up we have to have garbage like this happen.
It shouldn't be necessary for your average commuter vehicle to need premium fuel. Maybe if the treehuggers stopped carrying on and strapping ridiculous emissions laws to our cars then we might be able to have nice things lol. Engines are becoming so ridiculously complex and fragile, even for small commuter cars. I do run premium only fuel in my car, but that's because Im planning on getting a tune and I've just finished the rebuild, nor do I care about price or emissions. On an economy car for those who don't care about power this shouldn't be necessary.
I drive a truck that has several LSPI incidents per day and alot of knock incidents. It only occurs in the right enviroment (low engine speed, sudden drop or increase in ambient temp or change in DA, and a sudden throttle input from closed throttle.) If you ask me its because of the timing. I think these new engines have the timing way too advanced to try and save fuel or for more performance and pre-detonation occurs. Id like to know if anyone has ever had LSPI on an engine with low timing. Im guessing not.
I have a 2021 Nissan NV3500 and the V8 under load will rattle when I engine brake at lower speeds or coast and go to accelerate. These DI engines operate on a lean misfire as it is and that's probably part of the issue. But Honda already recalled 1 million motors for oil that's overcontaminated with gas and the same misfire issues
A few reasons why this occurs; substandard oil with poor additive packages that maximize oil octane when blow by makes it into the cylinders, low octane fuel that is more likely to ignite at higher cylinder temps rather than only when initiated by spark, high temp particles off the back of the valves preigniting large amounts of fuel during low speed / low rpm / large accelerator inputs
How does lubricant penetrate from under the scrapper and compression rings? You know the difference in the pressure during compression stroke in the combustion chamber and the crankcase. Why you showing jet of oil during compression stroke to the combustion chamber??
@@freeman8000 ya.... DI is a mistake amazing for racing or sports cars . but on a daily driver..... ill take the 2MPG and 20HP lost..... in exchange for not having to clean intake valves and run DEXOS oil
Hello, I was shocked to see the pictures of the broken rings and lands! This happened to my sbc 350 in a 87 corvette but only on the left bank pistons. Was running 93 octane 10.9:1 comp, computer tuned and a mild cam. No one knows what caused it ! Cylinder walls,combustion chamber and piston tops all looked normal ! Would love your input !
only on one bank?? . probably had SLIGHTLY higher compression on that bank..... due to a cylinder head that was resurfaced just a TAD more than the other head or they took more off the deck on that side.... if you had the block machined . or, depending on how the intake manifold works...... one of your TBI injectors might have been spraying just a BIT less fuel . their are companies that will "match" the two injectors..... so they spray in the same pattern, with the same pressure, and the same amount of fuel . . . . with 93 (which isnt 93 all the time.... it can LEGALLY be lower) and 10.9 compression..... you are in a VERY narrow window to have the power / ign timing you want....... yet avoid detonation . what is your dynamic compression? . . and ya.... im starting to think (if its TBI)..... that one injector was spraying a little less fuel ive seen TBI injectors work PERFECT at idle to 2500 RPM...... and 3500 RPM to red line (like 5000 on this GM 2.5 iron duke/tech 4) . but in that range where the mail truck (LLV) driver spends most of the day...... it would just stop spraying fuel... . . instead of "pist....pist....pist....pist" it was like... "pist.....PIIISSSTTT.................pist...................pist pist pist.........PISSST....pist pist.......pist.....ETC" . . . one way to tell is to use a timing light..... (as the injectors on a TBI are sorta controlled by the ignition modal) the flash of light is PERFECTLY in time with the injector pulse.... so you can CLEARLY see the spray pattern and amount . you can then move the timing light to number 2 (or 3, or 4...5,6,7,8!!)..... to see how the fuel sprays for the next cylinder some times the pickup coil just doesnt get a good reading on the one "tab"
what year, make, and model...and engine... are you driving??? if you have a cat converter..... VR1 is already doing damage to your cat.... (due to the zink) . if your car is stock.... WHY ARE YOU USING RACING OIL??? like seriously.... why do people think an oil change will fix a missfire..... or that you NEED to run racing oils in a STOCK engine it DOES NOT make any more HP.... . . and again.... you could actually be doing MORE damage than just detonation / pre-ignition . . . . VR1 is ONLY!!! designed to be used in flat tappet lifter engines..... due to the zink / ZDDP additive running ZDDP with a cat converter WILL!!! poisen the cat..... causing it to plug . and a plugged cat will cause ALL SORTS of issues low HP due to exhaust restriction low MPG due to engine working harder to overcome said exhaust restriction . and that back pressure can actually cause detonation!!!!! . . . and no.... engines dont need back pressure that is a myth if you could hold a VACUUM in the exhaust.... you would get more HP and fuel econ
TLDR........ stop using RACING OIL in your stock engine . try running ANY "dexos" certified oil....... DEXOS is literally designed to stop low speed pre-ignition...............
IMPORTANT NOTICE : For those who have a GASOLINE OPEL turbocharged engine : Dexos 2 (based on ACEA C3) is NO LONGER ALLOWED because of LSPI risks. You MUST use Dexos 1 gen2 (no matter the brand, the important is that the oil respects the Dexos 1 gen2 requirements). Dexos 2 remains allowed ONLY FOR DIESEL engines.
@@Private011 What makes you think it's getting LSPI at WOT. Is it downshifting? Perhaps smoother throttle application. I have the LHU in my '12 regal gs and it is a manual transmission and i've never noticed any issues even when it is lugged. I avoid lugging the engine now because I learned about this.
@@Heatherder Hey i hope you're still at youtube, I always shift early and accelerate hard I haven't been doing it for so long, my car is gasoline 1.6 non turbo It makes a gurgling sound when I accelerate hard on a high gear, I stopped doing now should I worry?
I've seen you commenting on this thing on many videos regarding to this. You should clarify one thing: this instruction is only for the newer B-series turbo engines from 2013 onwards. Older A-series turbo engines are not affected by this issue (A14NEL for example).
1:20 GM made the DEXOS certification for oil (at least, if you want to keep the warranty) . DEXOS only exists because the 1.4 (iirc) ecotech melted so many pistons due to LSPI..... if you are having issues in ANY brand of motor..... try running a DEXOS cert-ed oil
Nice infomercial with questionable linkages between your product and low speed pre-ignition. By the end of your wooden, dull delivery, even the camera doesn't believe you any more.

such a great info ! thanks a lot, today onward im your fan ~!
Who's here because your worried about your focus ST?
Just bought an ST and panic researching lol
@@mybillding6944 and how is your ST running after 4 months ?
How is the st I’m looking at getting one but this is putting me off
Me but with my kia rio 1.6 gdi
Mines really loud and ticky but drives fine 🤷♂️
The new API SP or GF6 oils removed calcium from the oil which was enabling lspi
thank you for this.
Where do i buy the pv1119 additive??? No where on the site have anywhere to purchase it
Your intro music sounds like the starting drums to Ever Decreasing Circles by Tipper, where's that from? Sounds great!
whooooaaaaaaa
nice one. i like tipper.

@@warriormonx I doubt these incidents happen with less timing

Dobak150 because rings on that piston are dead :-D
supar
cool
So LSPI is a gas engine issue , not so for direct injection diesel powered engines ?
Is this statement correct?
👍👍👍😍😍
This is why I switched to Castrol it has low calcium and high (1200-1500) calcium can cause LSPI with forced induction systems.
Who would’ve ever thought they would have the timing tune so far that you would need engine oil to protect against this.
chasing symptoms when all you need to do is build smaller lighter cars with port injection motors that last forever
@@freeman8000 ya.... DI is a mistake
amazing for racing or sports cars
.
but on a daily driver..... ill take the 2MPG and 20HP lost..... in exchange for not having to clean intake valves and run DEXOS oil

hes reading it from teleprompter. he has no idea what he is saying

.
probably had SLIGHTLY higher compression on that bank.....
due to a cylinder head that was resurfaced just a TAD more than the other head
or they took more off the deck on that side.... if you had the block machined
.
or, depending on how the intake manifold works......
one of your TBI injectors might have been spraying just a BIT less fuel
.
their are companies that will "match" the two injectors.....
so they spray in the same pattern, with the same pressure, and the same amount of fuel
.
.
.
.
with 93 (which isnt 93 all the time.... it can LEGALLY be lower) and 10.9 compression.....
you are in a VERY narrow window to have the power / ign timing you want....... yet avoid detonation
.
what is your dynamic compression?
.
.
and ya.... im starting to think (if its TBI)..... that one injector was spraying a little less fuel
ive seen TBI injectors work PERFECT at idle to 2500 RPM...... and 3500 RPM to red line (like 5000 on this GM 2.5 iron duke/tech 4)
.
but in that range where the mail truck (LLV) driver spends most of the day......
it would just stop spraying fuel...
.
.
instead of "pist....pist....pist....pist"
it was like... "pist.....PIIISSSTTT.................pist...................pist pist pist.........PISSST....pist pist.......pist.....ETC"
.
.
.
one way to tell is to use a timing light..... (as the injectors on a TBI are sorta controlled by the ignition modal)
the flash of light is PERFECTLY in time with the injector pulse....
so you can CLEARLY see the spray pattern and amount
.
you can then move the timing light to number 2 (or 3, or 4...5,6,7,8!!)..... to see how the fuel sprays for the next cylinder
some times the pickup coil just doesnt get a good reading on the one "tab"
My 2001 although is an injected car has 10.9:1 and runs fine in 87 for decades.
Could be the clearances were insufficient. Ring end gap or piston to cylinder.
