Going forward I'll be using M1 0W-20 EP. Ran through my stash of M1 AFE. I have 4 cars. 3 use the same oil and filter. My odd car was using Amsoil either AFL or EFM but I bought a stash of M1 0W-40 from Costco. My other 3 cars, '14 CR-V, '18 Legacy and '19 Impreza will be using M1 EP for the time being. THe Impreza is still using dealer fill and the Legacy used the last of my AFE.
