In my Walmart I have seen Valvoline 0w20 and Mobil 1 Ow20 in Qt bottles. My local Toyota Dealer sells Mobil 1. The price is 20 cents a quart less so the price is not the issue just wandering if you think one is better than the other. Its for a Toyota Tundra that does tons of starts and short trips. I work in 3 buildings all less than 2 miles apart and I go to several buildings through out the day. I am doing 5000 mile oil change
