Then Toyota should not be recommending change intervals that far apart.
I can't, of course. And it can't be said for certain that using only one brand of oil will prevent sludging. THAT is all I was trying to say.
Please cite a reputable source for this assertion. I've never heard of seal or gasket problems caused by using different brands of oil. I've always figured when an engine gets 200k miles on it, it's bound to have problems of that sort regardless of maintenance practices.
But again, what if a guy picks the wrong brand???... what are some bad brands? You didn't answer my previous questions.
No it doesn't. I changed my practices VERY recently, as in; my latest oil change last weekend was the first time I intentionally went 5k miles. The pic I posted was from a few months ago.
As most oil threads end up, we'll just have to agree to disagree, because neither of us is going to change the other's mind. Do whatever makes you feel good. I hope I haven't offended you, as that was certainly not my intent.
Sorry for the thread jacking wirebaugh, I'll shutup now.
