Auto StartStop

I can hear the sarcasm perfectly fine, thanks, lmao.

what's not lost on me is that you're genuinely suggesting that disabling stop/start under the pretense of minimizing wear on certain components is not a completely valid reason.

I genuinely am. The car was designed with S/S therefore it can use S/S.

There will be predictable wear for which the design has been adapted, there is predictable wear on all car components.

Your just talking to a wall at this point. Best to let it go or we're gonna be at 15 pages saying the same shit. Lol

With all due respect, you really need to stop and take a breath. You clearly aren't reading many of the responses here and are arguing blindly.

If nothing else your belief is wrong as evidenced however if you choose to turn it off then that is your choice. Just turn it off because you don't like it but don't pretend there is any logic behind it.

My Mustang actually does better mpg than many SUVs and trucks so actually it is green after all!

No, my belief is not wrong as evidenced on this thread that you continually deny. I don’t need you to tell me how to use my S/S, but thanks anyway. Getting better mileage than a gas hog doesn’t mean your car gets good mileage. You‘re the one that logic seems to evade so wear out your V8. I didn’t buy mine for mileage or pollution reasons any more than you did.

I did see an Eruption Green S550 last week - what a great colour that was

There must be something to this extra u guys require, u even add to the word color? But and although, always stay started is one of the reasons i was glad we got ours when we did.

Pretty sure all emissions values for vehicles are from strictly determined testing processes which vary by region based on their legislation

I have posted again this paper which contains many global references to remove your US political problems

Evidence?

I think you will find I am the only one who has actually posted any links to evidence rather than just opinions - just saying

Sorry I was not clear. You are correct that the testing is standardized and conducted in controlled facilities. I am suggesting it doesn't really match on road driving results.

There will be predictable wear for which the design has been adapted, there is predictable wear on all car components.

--> Humans are inherently unpredictable. You can scale components for predicted duty cycles across a broad range of driving styles and use cases, but there will always be outliers, extremes, and mishaps.

If someone is daily driving their car and using stopstart ten+ times a trip, two times a day, you are immediately on the upper end of that predicted user range.

If you really want to use the argument of "the car is designed with x in mind", then just look at cylinder deactivation on MOPAR's. How many years of timing issues and cam problems were there?

GM's V8's were recently recalled for engine failures. Part of the issue was the oil they were designed to be used with, 20 weight. In fact the primary fix for trucks that had not already encountered a failure was to switch to 5w30, mitigating the surface roughness problem of the cast.

Hell lets just use the Mustang as an example. I distinctly remember '03 Cobras burning up cylinder #7 from factory. Bad cooling on the driverside head.

How about all the MT82 issues out of the box for '12-'23 Mustangs. Many people had no problems, many did. Shit happens, but one thing in common with most of the failed MT82s was how they were driven. Hard, and raw.

Shit happens, and people see trends. Me, personally, I deactivate S/S because I know it is in fact creating excess wear and tear, even if at an almost immeasurable level. Its the same reason I don't let my battery discharge fully on my phone, why I don't drag my feet and scuff out the sole of my shoes, and why I rev match instead of slipping the clutch for downshifts. It's just unnecessary wear that I may not notice until its too late or too far gone. And the best part is, I sacrifice next to nothing and don't even think about these things by simply not doing them or disabling the systems. I am sacrificing next to nothing.

So yes, it is a perfectly valid argument as to why people would like to disable S/S. If we can't see eye to eye there, then theres nothing more to talk about.

But what you are quoting are design failures.

Incidentally cylinder deactivation has been used widely on modern engines without issues because it was designed properly.

More than happy to stop talking about it with you

I deactivate S/S just because it is annoying. I grew up driving POS cars and it reminds me too much of the days when my car would just die at a stop light.

New to the group so maybe this has been discussed (if so, I couldn’t find it.) I’m not a mechanical engineer but I feel like the stop/start feature in normal mode can’t be good for the car. Is this just some EPA bs that’s now required or does it really help with MPG? Does is hurt the motor/starter? 99% of my driving is stop light to stop light so it activates quite a lot on even a short drive. One kinda interesting note is it only “stops” for a short time when the AC is on, but seems like it’ll stay “stopped” forever with the AC and seat coolers off. I understand why, but with the AC on, it really seems pointless to turn itself off for 15-20 seconds. Also, it seems like the start up is kinda violent sometimes. Like the whole car feels like it jumped a bit. I learned to release the brake and not hit the gas pretty quickly but I don’t even know if this is a good feature. Thank you for your insight. Also, thanks to everyone that recommended good cleaning supplies on my last post.

Buy a Dark Horse problem solved.

Flashbacks of the days when that car grandma gave me would overheat at every stoplight, go ahead and ask my first wife about the adventures in walking we got to enjoy. Turned out to be melted cats but the feeling became a permanent reaction each time ‘it’ suddenly stopped by itself.

Ever have an album skip at one point in a song while listening to it as a teenager? Then 40 years later that song comes on the radio and you still cringe waiting for that skip?

That…lol.
