Pennzoil Platinum 0w20 2-5 Quart jugs, for wife's, and my car
Rotella T6 5w40, for the ATV, 2-1 gallon jugs
Valvoline 5w30, 4-5 Quart jugs, for my truck
Mobil 1 0w40, 3-5 Quart jugs, for the 3 snowmobiles.
Both our vehicles are spec'd for 5W-20, but I saw first hand the advantage of a winter fill of 0W-20 in my truck living in NW Ohio the prior 4 years. The 10w30 is for our ZTR mower.
