There has been talk about being able to mix viscosities of M1, so I went to Wally World yesterday and picked up a 5qrt jug of 5w-30 (I wanted 10w-30, but they were all out) and 2 qrts of 0w-40 for my truck (it has a 6.5 qrt sump). I picked up a good stock of motorcarft and Supertech filters while I was there too.
My question is can I mix the 0w- weights with the other weights of M1?
