I've always used Supertech Full Synthetic from Walmart for our Rav4 (0w20) and 4Runner (5w30). Rav4 needed changing at its 5,000 mile interval so I head to Walmart to get a jug, but they are out. No Walmarts @ me had it in stock, none. We're new Cosco members, so I head over there and get the Kirkland Full Synthetic 0w20 of which they had a pallet load of. I know it's the same oil from lurking here on BITOG for years. Just wanted to say thanks to all the members here for all the info y'all share and thanks to Cosco for saving the day!
