Years ago I heard that you could put a roll of toilet paper in the filter canister. I spoke to a Chevy service manager at a local dealer and he confirmed this. Since the oil just drains OVER the filter and not through it, using a roll of toilet paper works as good as buying an expensive wix filter, and maybe a bit better. At first I was concerned that the toilet paper would fall apart and clog my oil passages but that has not been the case. The roll stays perfectly in tact. So far so good. lol.....
