EPA to roll back stop/start requirement

I disabled mine very early in its life.

One thing he gets wrong is that the starter will wear out faster. They are actually beefed up in vehicles with stop/start and also use an AGM battery (at least on GM vehicles).

My two cents is Start/Stop should only be reserved for hybrids. There is no alternative propulsion on regular vehicle to help cover the gap of no engine power.

Exactly. In a hybrid, the electric starts you off and then the gas engine kicks on. With a stop/start, you have to wait to start. There have been instances of engines not restarting which causes headaches. And let's not talk about the wear and tear.

Yes. And hybrid "starter" is much more powerful and can instantly pull engine to working rpm zone for output.

To me this technology on any internal combustion engine is completely brain-dead. Further evidence to this is that the USPS has non-hybrid vehicles using it. What sounds good for the life of the starter motor about shutting the engine off and re-starting on a vehicle who's purpose is to make hundreds if not thousands of stops per day?

Just to clarify, there are differences in the way a gasoline hybrid is started, and pretty much everything else. Example would be all Chevy Equinoxs made after 2017. The starter used in the latter example is of identical construction to earlier designs that leave the engine running.

For most of my motorhead life the popular thinking was that most engine wear takes pace on start up, and that is why Police cars and the like (which are always left running ) can have incredible mileage and continue to be reliable.
I don't know if this is fact or fiction but, if true would not help the case for SS vehicles.

And that plays into the planned obsolescence agenda all automakers have adopted wholeheartedly after the cash-for-clunkers fiasco.

There really needs to be someone in charge of the EPA with gray hair and permanently scarred knuckles. Someone who doesn't have a pressing need to pluck his / her own head out of their rectum in order to see the same reality everyone with a clue sees.

I've disabled it in my diesel Sierra. Such a stupid useless damaging system. And I'm also looking at going from 0w20 to 0w30 or 40, especially during the summer months when towing the RV. As long as it's DexosD or Dexos 2 certified, I should be good regarding the warranty.

Something I've come across regarding hybrids with basically the same stop/start system. There are some concerns with wear as well as water formation but their oils have additives to counter that. Not so sure about regular gas stop/start vehicles.
