Oh and guys even a cheap Walmart Supertech/Tech2000 oil filter can go the distance with out failure in a moderately maintained vechile you do not need a $9-$16 oil filter that is just hype. Flow is so much more important then filtering in a full flow system. Now a larger filter can make a difference in insoluble levels though but you do not usualy need to spend a lot to get a larger filter. In fact Donaldson filters are some of the best filters out their and they are not that pricie either just hard to find. Baldwin and Hastings make a nice filter as well but I think Donaldson has a better media in their stratpore series then Baldwin and Hastings but they are great filters too.
