quote:The Havoline you used since '99 was made by Equilon, a joint venture between Shell, Texaco, and (I think) Saudi Aramco. The current Havoline is made by ChevronTexaco. Both are probably on the better side of average oils, and I don't know if it's the same oil...in fact it is different oil (as are all the others) due to the change from API-SJ to API-SL in 2002. Ken
Originally posted by Mike: I would say Havoline. I used 5W- 30t in my 1999 fleet surburban for 95,000 miles, changing oil every 5,000 miles and the truck is in like new condition. Never uses any oil and the engine have never been opened up. Can't go wrong with Havoline.
