Hi bitoger's.....looking for suggestions on an oil choice for my 2007 Mitsubishi Endeavor, 3.8L V6 (6G75), 33xxx on the odo. Have an UOA on the UOA forum, with some high lead showing. Always wanted to run a high end syn oil, but, in reality I like to change my oil 3 times a year, and that would be a waste with my 12-15k a year trend. Could be talked into twice a year with an A3 oil. This was my first UOA, and i think it is a cool thing to do, even though many question if they are of use in determining wear. They are cool, none the less. Anyway, my driving habits are very short trips during the week, with a 250 hwy miles on the weekends. Climate is from 0F in winter to 100F in summer. Owners manual calls for 5w20 (for easier starting and fuel economy), or 10W30 in high temperature operation. Some say that Mitsubishi's love thick oil (40 weight). My syn oils of choice are RL 5w20/30, GC, & M1 0w40. Really thinking about running Pennzoil T&SUV syn blend, just to add to this forum's database, as I cannot find anyone else who is running this oil, and the savings would offset the cost of UOA's. Anyone have experience with the Mitsubishi 3.8, or have any suggestionns ? Prefer not to run dino, even though I know it would do fine for me. I work nights, any my vehicle sits outside from 6pm to 7am. Thanks for your suggestions and replies.....jr
