About the comment earlier about wider range being better, I have actually read in a pretty comprehensive oil analysis/research article online that a wider range is worse.
The reasoning they stated was that to achieve such numbers, an oil needs special modifiers that allow it to bond to itself differently at different temperatures. The idea being a single grade oil is very stable, while 0w-40 wouldnt be as much because it has many things in it working to bond differently as it changes temp.
So 10w-30 is actually more stable in the long run, than even 0w-30 and so forth.
But really, these are all somewhat small points. As long as you get a quality oil, even as cheap as Castrol GTX, for $1.50 a quart, youll be fine I believe. Change it regularly, and deal with the other problems that come up. If you are really a spirited driver, I WOULD invest in a some research to what breaks down the least. I once ran cheap Chevron oil (dont laugh) in my 280Z that I would drive the hell out of. After about 700 miles, the oil wasnt what it used to be. Seemed to be like very thin, like water. I personally believe it broke down and no longer really offered much protection for anything.
Castrol GTX however, for the money, is the best dino oil i believe.
Hope that helps.
No one here mentions redline I noticed. I personally havent used it, but some racers live by it, especially in the American car segment.l What do you guys think?
