I’d use M1 0w40 but HPL is really all I need. Cause it worksI like #2. That’s what my cars typically look like. I buy Mobil One in the needed viscosity from Walmart because it is convenient. Nothing fancy. Can’t imagine the Quaker State, Penzoil, Castrol, Valvoline full synthetics would look that different but I stick with M1 out of routine now.
