I know your not asking me, but i thought i'd answer anyway
I've used lots of pennzoil, quakerstate, and formula shell. Formula Shell and Quakerstate and similar in their formulations, being slightly less moly than pennzoil, but more boron, which is in my opinion a good thing.
Pennzoil is slightly more expensive than the other two due to slightly better base oils, which help give it ever so slightly better pour temps and slightly better (less) cold cranking viscosity, but while i may be in the minority, i like the added boron in QS and Shell.
If you can find FormulaShell for a good price, by all means use it with confidence. It's an excellent oil. Their 5w30 and 10w30 are blended a bit on the beefy side but are still energy conserving, which i like. The 5 qt jugs at AutoZone are an excellent value.
Formula Shell is the new Havoline
