I watched the AU Parliament in session once. That was good enough for me. Are they always that rowdy? Quite embarrassing actually.
Petro-Canuck used to call their Duron 20W20, now they list it as SAE 20, but in the text they show a 15W CC and pumping pass.
Chevron is the only other big-un around here that lists a 20 in their Delo 400. They dropped the SAPS in all but the 30&40 below the old CF-2.
There must be a call for it, likely as a multi-task fluid that in a pinch can be poured in, over or on just about anything.
