I work at a shop- the other day a '10 Yota came in for a oil change and required 0w-20. We don't stock 0w-20, so we had some delivered. M1 AFE. This got me to thinking... Why not kill two birds with one stone so to speak and stock 0w-20 to use for both apps?
Now you have to understand, my boss will probably not go for it... He's decidedly old school and one of the biggest manual wavers I've ever seen. If 0-20 is called for, 5-20 absolutely cannot go in the engine or vice versa... Never mind at the current temps nothing and/or no one will ever be the wiser. When I suggested it, he winced and said "We'll talk to my oil rep"... Uh-huh.....
