I’m at 65k miles on a mix of Castrol Professional 0w-20 (dealership oil), Mobil1 0w-20 AFE, Castrol Edge 0w-20, Castrol Edge Extreme Performance 0w-20, and now Pennzoil Ulta Platinum 0w-20. Conditions were split between California and Canada. Out of all of those, the Castrol Edge EP was the only one that the engine consumed oil. I’ll probably keep going with Pennzoil Platinum since it’s a little thicker for fuel dilution. The dealerships in Canada offer Petro-Canada Supreme for a reasonable price that I’ve been meaning to try also. I think that’s what they use in the dealerships here instead of Castrol. Just change it often, especially if you’re in severe service territory.
