What's the oil filter thread supposed to be on a 3.5? I just changed the oil in my company car today (there's a reason why I was changing the oil in a company car; company pays for oil change every 7K miles, but the last change in this car was done two users ago at a Jiffy Lube. I got that ancient crap out of there and replaced it with some Mobil 1. Normally 7K miles is only 4 months or so, but not in this case, because it sat around for a long time.) Anyway I had been thinking, if I could convince the shop that does our oil changes to go along with it, that I would put a CM filter on the car and pay him extra to keep using Mobil 1 because I'm going to need a decent car, and they often offer the cars to the people that have been driving them when the lease is up. Per CM's web site, the filter thread is 18mm (can't seem to access it right now, but it's linked from http://www.cmfilters.com/spin-on.cfm ) but both the filter I took off was stamped "13/16" The filter I just bought at Carquest was stamped similarly so I just shrugged and installed it. is that correct, or did I just install the wrong filter (for the second time?)
