I bought 20-25 quarts of Toyota 0W20, three months ago for $2.75/qt. Bought it on the black market (Craigslist), from a guy who said he was a former dealership employee. I asked no other questions, and quickly transferred it to my car trunk. It is hard to turn down a great deal.
I hope Toyota 0W20 agrees with my Ford engines. I picked up 2 extra mpg using Honda 0W20 in my 2011 Ford Escape 4 cylinder, over the standard Motorcraft 5W20 blend. No UAO's, but I give the Honda oil high marks. No ill effects and like a good beer - it went down smooth!
The Toyota 0W20 oil, will have to wait, until I use up a dozen Havoline 0W20 (which are on the "on deck circle") for my personal testing.
