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.

The oil sludge in the hot turbo is also a VW group thing and I'm sure lots of others without water cooled turbos have similar problems.

@@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.

When i start my 2024 Silverado, i start the vehicle, put on my seatbelt, and immediately disable the start/stop. Its now in muscle memory.

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.

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 👍🏻

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.

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?

My 2002 Prius is far more annoying vibrating away at idle for no reason than when it cuts off.

Allegedly some cars ECU keep track of the number on starts a starter motor has done and flags it as needing to be replaced.

If I find definitive evidence of extra wear over idling on a modern engine due to Stop/Start I’ll disable it via the ECU pronto.

A friend of my rented a car with stop start. He said he almost took it back because it kept stalling. Wouldn’t that be embarrassing.

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.

I had it permanent switched off with OBDEleven

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.

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 🙏

Cam belt wear ? I have S/S on 2019 1.0 Seat Ibiza MPI. Cam belt advised to be replaced every 5 years. Batteries AGM or EFB. I have a EFB, holds the charge well then I switch off the S/S system manually as well auto run lights really use air con. Thing that truly annoys me about VAG is their manuals tell you to take your car to a dealership for basic maintenence tasks like replace a battery.

They make even a battery change complex, the car needs to know the battery stats and capabilities in order to monitor and allow the stop start to work, so fitting a new battery requires a "recode" which even smaller non franchised garages can offer now. In the past we could just buy a battery bolt it in and be good to go. They call this progress? Personally I've found I get better quality work and a better service using a local trusted garage rather than a main dealer, the downside is that people often like to see main dealer stamps in service books when buying but I think this is changing as people realize it is the work done rather than the person doing it that matters.

My start stop ford eco boost has just cost me 4k for a new engine as the turbo failed due to lack of oil, constant stop starting.

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.

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

that not true partialy politic forced to make enginer stop star engine so basicaly is a nono for me

I just keep turning it off..annoying eco crap thats not needed and probably isn't doing your car any good.

Why we pay extra for this shite?😮

Just don’t believe it sorry
