Hi everyone, first post here at BITOG! Been lurking a few days and thought I'd create an account, learn some more info and try to contribute eventually with UOAs and such. Anyway, I had a question about which type of oil should work best for my driving conditions, and my vehicle. 1. What kind of vehicle you have: 2005 Ford Escape 3.0 V6 4x4 2. What your owner's manual says: All I can find is 5w20 and that Motorcraft oil is highly recommended. I'm looking for a API S/N oil anyway. 3. Where you live: Central Missouri 4. How you drive: Moderate, not light, not real hard, but I have the bad habit of unintentionally racing people at stop lights. Never go above 4k rpms 5. What your daily drive is like: 40 mi round trip, 60% highway 30% city 7% paved back roads 3% gravel back road (I live on a 1/2 mi stretch of gravel road) 6. Whether your car has any known problems: None that I know of I am the original owner of the Escape, which currently has 114,400 miles. Oil was changed with Motorcraft Syn Blend 5w20 and a Motorcraft 820s filter 1K miles ago, and Motorcraft oils and filters have been used all its life with no OCI going over 5K. The book recommends 5K intervals under ideal conditions, 3K for anything otherwise, but I figured since that was when oil was made a decade ago, things are different now with new oil standards? My main goal is to extend my OCI to 7.5K-10K, and I wanted to know if this was do-able if I used a different type of oil, even though the book says 5K. Motorcraft has worked, but I feel like experimenting to see if there is a better one out there for my needs. Have been considering Mobil 1 Extended Performance with some sort of synthetic oil filter. Then again, I've heard good stuff on the forum and been really suprised by the results some are getting with the Super Tech Wally-World synthetic oil, and have been considering that. I'm not really concerned about leaks since the car has been well taken care of with regular oil changes, and Motorcraft is a syn blend anyway. So what do you guys think, am I in a position where a different oil would work better for me, and can I do 7.5K OCI on a 2005 car living on a 1/2 mi stretch of dirt road?
