Was at advance auto last night to take advantage of their qsud deal and saw that they now stock Havoline synthetic in 5w20 and 5w30. I could hardly believe my eyes as I have never seen this stuff anywhere in my area. Are there any voa's or even uoa's of this or the Chevron equivalent? I searched but didn't have any luck. I know its supposed to be good stuff but I was curious what is actually in it.
