Mobil 1 vs Red Line? Cost and Performance Comparison?

[YngTLCOwner]

Biff,
I was at Costco here in So. California this past weekend and saw that they had it but not 0w x 40. They did have 10w x 30 available. Which Costco do you go to? Do they stock 0w x 40?

I go to the one in Alhambra. I only saw 5w30

No 0w-40 at the ones on the East Coast either (VA). Oh well, looks like Autozone it is!

All,

Kragen (and maybe other Parts America associates) have all synthetic motor oils in stock for $4/qt. And this applies for any brands. Stack up guys!!!
