ORIGINAL: Jeremiah 29:11
I agree with Shell regular oil (Revell????) and gasoline being the best.
They have a major engine facility in Houston where they test gasoline and oil in engines and it like a huge ware house where all they is run engine for thousands of hours doing data acquisition.
I'm sure that Shell is one of the best considering they landed on the top tier fuel list, I just have had better luck with other ones is all.
The other thing I disagree with that list on is the no need for using premium point. Although it might not help the fuel economy, you should go with what is recommended because then the engine does not run at it's potential and sometimes despite what they would like to believe the electronics (like the water tight compartments on the Titanic) are not perfect and sometime will fail and the engine will detonate. Plus, premium can also be useful in the case of some gas stations like Shell that add extra additives and detergents that help to keep your engine clean.
