I drive a turbo diesel with a stop/start system, I always switch it off for the fear of having the engine shut off while the turbo is hot. My turbo is not water cooled so i dont want to take the chance. Plus we cant blindly trust in manufacturers to build parts that will last a very long time. Many say components will last the life of the vehicle, for all we know, the life of the vehicle could be 8 years or less. Idk, because idling too long is a risk, constant stop start is a risk. Best solution to me is just keep up on top of maintenance and hope for the best.
Its only bad if you idle for hours at a time. Other than that, yeah shutting the motor down while the turbo is screaming hot just cooks the oil inside of it. Then you get sludge and everything just falls apart, at least on the Hyundais. They suffer the most, my mothers palasaide started burning oil after about 40k miles. Did a compression test and cylinders 3, 4, 5, and 6 were DONE.
@@torquecars oh definitely. Especially in the b5 series. The design was pretty horrendous with the fact they only recommended blended oil and the oil pickup which frequently clogged pretty much meant you had to lift the motor out of the frame since that was the only way you could access the pan. I saw some people drill a hole in the pan with a hole saw to get to the pick up LOL 😂
The best thing about this system is that button that switches it off. The only thing I hope is that the previous owner has done the same thing or has not done much driving using it, hopefully I got it with only 29K miles.
Apples to oranges. You over-engineer a starter motor (which should have been done 50 years ago). Of course it lasts longer now. Second point, Fuel in engine oil. Every stop-start system has more. Is that really a 'green solution'? 3rd point, the 1 second extra it takes to pull away at traffic lights means someone else behind is trapped on a red light. Do they have stop-start? 4th point. You are carrying additional battery WEIGHT, and where does the electrolyte and cells come from exactly? (not very green is it?). 4th point, the smaller engines get, the more boost turbos have to make. Heat soak in a hight pressure turbo is the reason why we all bought a turbo timer to keep the engine running to provide oil to the bearings. Stop-start is political and not physical, just like electric vehicles. It might slightly reduce emissions in built up areas at the expense of emissions, engine wear, cost, service, everywhere else.
You make some exceptional points there my friend. On point 3 I would like to add it depends on the car. I've driven some that start as soon as the car in front starts moving (2023 Audi A3 with adaptive cruise control), and my own older A3's engine is back on before I've lifted the clutch to pull away it really is almost instant. But I guess the key here is almost. There are two many green solutions out there that when you dissect it are actually worse in terms of emissions. If only we could keep our cars for 25 years and not have to keep replacing them, they may guzzle the gas but I bet that still outweighs the cost of production and shipping on a new car.
I drove a SEAT Ibiza automatic recently and it did not appear to have a button to disable stop/start. Handbook said the way to prevent it kicking in was to only press the footbrake lightly when coming to a halt. It sort of worked, when it was practical to do so, but seemed rather ridiculous not being sure of the engine was going to cut out or not.Handbook did have a picture showing that on a manual Ibiza there is a button to disable stop/start!
I have a Mini Cooper with stop/start. The first battery lasted just over two years and was replaced under the service plan. Since then I always turn off the stop/start function and the new battery has lasted 5 years so far with no problem. Yes, it is a larger battery - 70Ah with a very high cold cranking current spec, but it didn't last.
Good explanation for those of us who are not experts on automobile engines. At first I hated the Start/Stop system on my new car, but now I accept it. When driving within the city I temporarily disable the system by just pressing a button.
My F150 2.7 turbo would shut off at red lights just 1 mile from home. The windshield wasn't even completely defrosted yet. Made my own heavy duty trailer harness with two large power resisters which mimic trailer brake lights. Truck thinks I'm always towing and stop/start is always disabled. Other benefits, 1. Blinks 5 times vs 3 when you tap the blinker stalk. 2. Charges my aux AGM battery in the bed (canopy/topper mini camper) via spliced trailer battery wire. My 8 year old starter AGM battery was still starting the truck normally when I recently replaced it due to battery saver function always activating when I turned off the ignition and wanted to listen to the radio.
- Project Farm on his YT video on this found via scientific analysis of oil samples that synthetic engine oil can go 18 months in the engine no problem, if the miles done are low. Personally on my VAG TDI powered cars I change the oil every 7500 miles. Most of their miles are longer journeys and both have done between 100-200k miles.
What do you think about stop start technology? Do you disable it all of the time, some of the time, or just leave it on to do it's think. How clever is the stop start setup on your car?
I shut the cursed thing off every time I get in my 19 F 150 Most of the time I take an old trailer plug and shove it in during the dry months which turns the garbage off. It does shut off the backup guidance lines but I can live with that. There’s just something about shutting down turbos and considering those tiny fine screened oil inlet filters that rubs me the wrong way. You just don’t do that with turbocharged engines even if the manufacturer says it’s ok. Why, because they will happily lie to your face if Big Brother says to and you can’t trust either of them as far as you can chuck them. Gov is ruled by activist number crunchers who have no concern for your well being while manufacturers just want to sell more overpriced things.
Interesting takes on both options. My wife’s Disco sport has it and the first time it kicks in I remember to switch it off. Usually top of the road on an incline with a blind entrance where you have to boot it and to have it switch off is frustrating and potentially dangerous. Take what you say about over engineering but think all the electrical tubings on modern cars will knock batteries out faster than without. Keep up the good content 👍🏻
I don't mind having the stop/start system on in a manual because it only activates when the clutch is released in neutral. I'll only ever do that if I'm waiting at lights for more than a moment. In other cases like queuing at a rounddabout the engine will keep running and be ready to go provided it's in gear
The ring gear in my BMW diesel just separated from the flex plate. I have disabled stop start but one of the rare times I used eco pro mode the other day, I encountered road works, engine stopped (always freaks me out) so I put it back into comfort, engine started, a few days later the flywheel threw a wobbly. Mechanic says it must have occurred when starter has engaged recently.... hmmm.
Sorry to hear that so I guess you make a point of switching it off or disabling it. I'll be interested to hear from others with Eco Boost engines on this topic.
You'll probably find with the Ecoboost that it won't be because of the Stop/Start tech that you had lack of oil.. the wet belts are notorious for breaking up and eventually blocking the gauze on the oil pump which in turn kills the engine/turbo.
Auto stop starts damages many parts of your engine, Modern Auto stop start uses a compression start from the GDI injectors. So don’t worry about your stater motor. Things to be concerned about. Everytime your stops it experiences heat soak which causes carbon build up. The PVC system sucks excess vapor from your crank case which contains vaporized oil. Use a very high quality oil and changed it every 5k miles or once a year what ever comes first.This is even more detriments if your car has a turbo charger on it which is oil cooled. The turbo bearing spins at very high speeds. Old school Turbo guys knew to let the engine run for a few minutes to allow the oil to cool the bearing. Auto stop start shits down the engine allowing the oil in the bearing to turn into carbon eventually destroying the bearing. The most strain on your value train occurred during starts even when at operation temperature.. This wears out cam belts and chains. If these fail it will cause severe engine damage.
I turn mine off as I've found I get better economy with it still on idle at the lights and junctions. Plus I feel it doesn't do the starter motor any good because they aren't heavy duty and not really designed to constantly keep starting an engine. Just my thoughts and it works for me.
I absolutely hate the stop start system will create more wear and will notice in the longer term, also what do you think of forte engine oil treatment for oil burning? Thanks 🙏
Wish everybody had stop/start, then I don't have to sit in stalled traffic or at red lights breathing in all the exhaust fumes from all the poorly maintained and smoky cars around me, that the ventilation/A/c is pulling in..
I have never l owned a motor vehicle or own any vehicle with a stop start system just like to point out a starter motor has only a certain number of cycles before it will fail as most cars are are automatic now you are pretty well stuffed if your starter motor fails were in a manual if you are on a slope you can start it l have replaced many starter motors in many of my vehicles l have owned and replaced many batteries as for engine wear with a stop start system the car is warmed up when the engine is stopped its not a big deal
I am having an issue with oil dilution in my 2017 Range Rover 4.4 SD V8. Do you think switching off the Auto Stop/Start would help to reduce or stop it happening?
Do you do lots of short journeys? Those engines take a while to properly warm up and during warm up they are dumping a lot of moisture into the oil. Getting the engine properly warm is a good idea and if stop start is preventing this then I would certainly consider turning it off.
@@torquecars What kind of moisture are you talking about? The mechanism of getting engine oil diluted in diesel engines has absolutely nothing to do with with some unspecified "moisture" in the oil, where did you get that one 😀 It is failed DPF regeneration cycles that dump not fully burnt fuel in the oil, fuel that gets injected into the DPF filter to burn the particles. It will happen if the engine stops in the middle of the DPF regen cycle and modern start stop systems are certainly designed not to stop the engine in the middle of a regen cycles. Lots of short trips definitely contributes to oil dilution, if that's how you mainly use the car, sell it and get a petrol one.
I will try to use a word that is more specific though as moisture is often thought of as water. Moisture Definition: water or other liquid diffused in a small quantity as vapour. This would obviously include fuel. Interestingly when you put a catch can on these you'll notice a lot of liquid building up when you do short journeys, this is not fuel but a by product of the combustion process and this often ends up in the oil, but in most cases will evaporate away when you get a decent amount of heat in the engine. I have actually just shot a video on oil dilution as i thought that was an interesting subject so when I've edited it and published it please let me know your thoughts on it - I'm always striving to improve my knowledge and then share this with the community.
Absolutely dumbest invention. Just imagine how often you’ll be changing that starter, lol. Engines are not over engineered but manufacturers spend millions on studies that can design engines parts that last till the warranty runs out then brake downs are expected as that’s where the money is made, in repairs.
You Don't believe it does or doesn't cause damage? Please don't apologize, I've learned that people all have very different experiences with cars and car problems and by hearing as many points of view as possible we can have a more rounded out opinion.
I too am curious. We had it on our 22 Silverado but I turned it off because, to me anyway, that engine already had the cylinder deactivate, so why add more stress onto it. Now we own something we've never owned before a Nissan Rogue with the 1.5 turbo 3 cylinder. I'm playing with the system; that is I'm keeping close fuel economy lists checking whether or not it helps. Plus I'm rereading the warranty closely to see what, if anything, is covered. I'm never too old to learn and like you're videos and the comments
