Three questions for the oil guru's out there! 1. I was at Walmart this past weekend looking for Texaco Havoline motor oil. They had it for 0.94 a quart. I didn't buy it because it said "equilon" on the back. I heard on this board that wasn't good. My last Havoline oil change was with "chevron/texaco" Havoline bought at Autozone, but it was $1.40. Why is equilon a concern???? I ended up buying Valvoline standard GF-3 oil. 2. What is MOLY? And why should I care?? 3. Opinions on the Regular Valvoline 10w-30 please? Thanks in advance!
