Auto StartStop

This should be easily visible in a used oil analysis, and I have plenty for my Coyote. None show abnormal bearing wear and I use start/stop.

Did you compare them with one without start stop for a long period?

Yeah. I try not to mogg on something just for the sake of mogging it, but I have opinions that I carry. I'd like to think they are, at the very least, somewhat reasonable.

I will say though, being told that its an EPA emissions thing, then sitting through a lecture being told that on BMW's the primary programming concern is to keep occupants 'comfortable' (will switch the engine back on if the EC it believes occupant cabin is too warm without sufficient AC) left a sour taste in my mouth. I'm inclined to believe that mentality extends to a majority of brands.

So you claim its to reduce emissions, but if that means the cabin temp increases by a few degrees you say "fuck it" and run the engine? Nahhhhhhh.

Obviously not an issue with hybrids

Extra waste?
That's partly true, according to the ANWB (Royal Dutch Touring Club). Research has shown that wear on the crankshaft's main bearings is more common in modern models than before, and this is thought to be due to the start/stop system. "During the stop, the lubricating oil film even disappears, and upon subsequent restarting, there's even increased wear," according to a car expert from the interest group.

For what its worth, bearing wear/bad bearings are hardly what kills most engines nowadays. Its usually excessive cylinder bore wear, oil consumption, etc.

If your bearings are going, on most engines its due to an oiling issue, or driver error with over-revving when cold, etc.

An OCI interval for each. 5K miles.

I could say it a third and fourth time, and you’d still keep repeating your same story. Enjoy your ASS! I’m done with your posts!

We know - you have said it twice now!

Lots of performance cars are hybrids now

Excluding all of the current engine recalls that involve spun bearings, I'd agree.

I guess not? I dunno. I know next to nothing about modern hybrid systems. I cut my teeth on SAAB's and followed that shortly with old British and American cars.

I attended a few seminars on modern diagnostics, attended a few courses, but I never really had to use them since my work was rarely on modern cars. It was usually engine work on MGB's, Jags, Triumphs, etc.

Hahah, its been a rough few months

I have 2 coins.
One is used and abused constantly.
The other one is just sitting on the table.

Which coin will look better in the long run?

5k miles is a brand new car. Would be strange to conclude that there is nothing wrong.
If there is something wrong with a 5k car, than Ford should be ashamed making products that show wear and tear after 5k.

At some point you're going to need to put up evidence, and not speculation, that it's harmful for our specific engines.

It depends on the driving circumstances but the impact of S/S is well researched. Which paper are you quoting? The savings are not primarily financial however, they are environmental both locally and globally.

Auto Stop-Start Fuel Consumption Benefits

Practical investigation and evaluation of the Start/Stop system's impact on the engine's fuel use, noise output, and pollutant emissions - ScienceDirect

Two years ago during my Fire Science degree, I was writing about electric cars and came across the article about auto stop/start. I believe Michigan university was the ones who published it. I will quote the link when I get back on my laptop.

Here an article in The Netherlands and Germany, research by ADAC that Start Stop is bad for your car.

Many drivers have a love-hate relationship with the start/stop system that has been standard in most modern cars since 2012. It saves fuel and is good for the environment, but the systematic engine shutdown also causes many annoyances. Moreover, many drivers think that the frequent starting and stopping is bad for the engine.

Extra waste?
That's partly true, according to the ANWB (Royal Dutch Touring Club). Research has shown that wear on the crankshaft's main bearings is more common in modern models than before, and this is thought to be due to the start/stop system. "During the stop, the lubricating oil film even disappears, and upon subsequent restarting, there's even increased wear," according to a car expert from the interest group.

Many drivers are particularly irritated by the fact that starting takes a little longer, especially in a manual transmission car. It's no wonder that increasingly more "dongles" are being offered for the diagnostics port, for apps that permanently disable the start-stop system in cars with combustion engines.

Is that what it actually says?

Research has shown that wear on the crankshaft's main bearings is more common in modern models than before, and this is thought to be due to the start/stop system. - according to a single person

Toyota don't seem to be having any problems with crankshaft wear in the Prius that does way more stop start cycles with a longer duration than older S/S systems such as on the Mustang. And we all know the sort of stratospheric mileages the Prius can do on the original engine.

Does the Corvette BMS have any settings you can change? Ford have different setting (profiles) for different battery types (rating and type) which you can change using Forscan or similar

Didn’t need to fiddle with the settings to recognize the enhancement

If it is showing no abnormal wear what are you comparing? What can be better than no abnormal wear other than 'really no abnormal wear'?
