I seem to have ignited the honor/ignore the warranty requirements discussions here. I should have known better having been on automotive social media sites for almost 20 years. Was hoping that BITOG would be a little less rambunctious but seems I was wrong.
I got the info I wanted. But again, was not expecting the exuberance of the ignore the warranty reqts discussions. The industry I retired from was huge on verbatim compliance with the written rules. Being nuclear I embraced that and carried into my private life when it came to written requirements from a manufacturer who expected me to perform in a manner that they laid out for me. And throw in the Magnuson Moss warranty act, well then what would expect. Yes I know what some of the replies might be to that, but also remember, if the Manufacturer feels you violated the warranty, now you have to prove you didn't. If they do a UOA and the numbers pertaining to C20, or whatever spec you are supposed to use, aren't there or obviously different, one could be refused. And I can tell you that maybe the chances of that happening are extremely small, but my budget is infinitely smaller compared to theirs so why even take the chance.
Besides, the Mobil1 ESP X2 0W-20 is a very good oil AND actually costs less than the Amsoil or HPL prices for their product that I have been able to find. HPL-$16.95/QT, Amsoil-$14.99/QT, Mobil1-$11.67/QT.
Let the fire storm continue.
