A filter is NOT A filter. Many better ones have better seals, drain back valves, etc.
I use K&N, I'd use mobil 1 but I've never seen one.
Full synthetic oil is your friend.
I buy the Mobil 1 filters.
I buy them at Autozone, and they aren't cheap. Most filters cost around $5, but these are like $10.
And as Diablo said...A filter is not a filter.
If you look on the back at the fine print, you will see a percentage, stating what percent of particles of a certain size were caught when they made (I believe) two passes through the filter. Mobil 1 and a few others are like 97%, while others may be a few percent lower. 97% is the highest rating I have seen.
I'd bet that since most of you didn't know that Mobil 1 makes/sells filters that they are new on the market. Guess I got lucky that they sell them in STL?
I'd just go with Mobil 1 oil and a Mobil 1 filter.
