Re: Oil filter talk...
I purchased 2 cases of Wix filters that lasted a couple of years when I was driving my truck a lot. Now I just pick up the 1995 when and where it is on sale.
As for the oil not getting as dirty as fast, have you ever thought that it might not be cleaning as well as those that get dirtier quicker?
The only way to know what your oil is doing or how long it will last is to get it analyzed. It doesn't cost that much and it may head off a major problem down the road.
