Oh, another thing on oil filters. We had a discussion on oil filters in class. My instructor says that some of those fancy expensive oil filters may actually cause harm. What happens is, if they have smaller pores, they end up restricting more flow and it blows a backup valve or something and you end up cycling unfiltered oil. He mentioned a study where they found cars using these filters were infact, doing that. He says you shuold pick a filter that keeps a good balance of filtering particles and keeping good flow. The best bet would be to buy the OEM filter.
He says, if it'll filter out anything smaller than .002 in. then it'll work just fine. (I think that was the particle size he mentioned).
He mentioned air filters too. He said, the same thing. More filtering material, the more you reduce flow.
Just passing it on for FYI if you cared or didn't already know.
