I run Mobil 1 full synthetic in ALL of my vehicles.
Since I drive a truck for a living and am gone for extended periods of time, read 6 weeks at a time, I run the 15,000 mile extended performance in the wife's Suburban and the oversized Wix filters and I usually change the filter out half way through at around 7,500 miles and top off the oil and then at 15,000 I change the oil and filter again. It may not be necessary to change the filter half way through but it makes me feel all warm and fuzzy.
With that being said....
Opinions are like Azzh... Err... Ah....Noses, yeah noses thats what I meant to say, everyone has one and they all smell.... Lol
So do what makes you feel good. I have used Mobil 1 for years and any engine that I have had to go inside of that has ran Mobil 1 was clean as a whistle inside.... But I think any synthetic would be the same.... I have heard good things about the Walmart supertech over on the website "Bobistheoilguy".
My 2 cents.... YMMV
