I joined BITOG when I was trying to find out if I really had to change my oil once a year in my 1985 Corvette despite the fact that it hardly ever gets driven 3k in a year let alone 5, 7.5 or 10k.
It seems commonplace for both automakers and oil producers to recommend the one year thing. The cars I have personally owned usually were 7.5k/1 year for my Kias or OLM/1 year for my GMs. Oil wise there is Mobil 1 AP an Amsoil 15/25k. I am pretty sure even my small engines even call for annual oil changes.
Look, I follow the manual just because I see no reason for manufacturers to lie about something like this. Most people don't give a (edit-mod) about cars let alone oil chemistry and whatnot.
I bought a 2019 Chevrolet Volt (I like it regardless of any negative attributes everyone has gone out of their way to make known to me since I bought it LOL although I am not a fanboy either. I know some people think it is stupid/gm is crap, etc, etc so lets just talk about the oil part plz) and interestingly enough, they say OLM or 2 years.
So OLM or 2 year seems interesting to me because of the pervasiveness of the 1 year thing. In addition, it seems like there is a consensus that infrequent usage, short trips, and low temperatures are the reason it still needs to be changed. Those are literally the operating conditions for the Volt's ICE.
Pretty much if you drive the car in the default mode, it runs on battery for about 60 miles. The engine might kick on a few times if it is really cold to assist with cabin heating or battery coolant temperature management. Like on and off many times in a short time period ESPECIALLY during cold conditions. When the battery runs out, the car pretty much uses the ICE to charge the battery a little and then burn off the excess charge above the minimum. I am sure it is not a direct comparison or even correct, but my understanding is that some trains use diesel to make electric and then use the electric to move the train -- it is kind of like that.
In addition, if you never use up the 60 miles between charges and have no need to burn fuel to move, the car will run the engine to keep the average fuel age in the tank off etc and etc.
So how, if oil spoils over time, and almost always specified 1 year mark, how does this make sense? Some folks (I think amsoil so idk) say that once you run the engine once, the chemical reactions have started and will spoil the oil regardless of use over time. So what gives? The Gen 2 Volt ICE is direct injection as well afaik.
I am not really looking for an answer or advice, just thought it was an interesting talking point for this forum. Any thoughts?
