hmm interesting how much dose an oil analysis usually cost and where can you get it done? used the mobil cause i was told that in the newer gm's ('00 an up i guess) mobil1 is standard from the factory and i haven't noticed any noise. i was considering switching to the high-mileage mobil1 5w-30 oil but now i'm leary
Mobil 1 has come factory in cars such as the corvette and the GTO. There may be some other high performance vehicles that it came in. Mobil conventional oil has been the factory fill for all of GM's other vehicles for quite a few years now unless it has changed recently.
I'm not telling people not to use it if they have had good luck with it. I personally will not use it again and from most of the oil analysis results I've read on the bobistheoilguy.com website, Mobil 1 has not gotten better over the years. I just think that for the money, there are better oils out there. I think your engine will last just fine with Mobil 1 if thats what you want to use. Take care.
