Thanks for all the feedback. I also had a chance to look through several sources and the weight they post is only a recommendation. If they wanted you to use a specific type of weight and or oil they would have to give it to you for free as per US law. (i.e. bmw)

My oil change will be done next week and I decided that i was going to use the 5w 20 from Mobil fully synthetic. The reason I asked about the weight is that I like Mobil
EP and they don't offer that weight(0w-20). I use that in my explorer which also calls for a 5w20 and never had any problems and if anything helped maintain sticker or higher MPG.

Living in Texas, I always worry about how well oil is maintained 100 degree weather + whatever is inside the engine. I have come to the belief that if it doesnt survive Texas heat it was not meant to be else where.

I also feel that from all the research I have done. It does not matter what you end up putting in as long as you change it when your suppose to do so and keep up other preventive items. I just happen to prefer Mobil ;-).
