M1 15W50 is actually one of the thinnest 50 weights.
Viscosity @ 100ºC, cSt (ASTM D445) 18
GTX High Mileage 20W50 is 20.3
I want in on this p1ssing competition:
Penrite HPR 50 (40-70 mineral oil, no W rating) with a 100 C Viscosity of 30.5 cSt, and 1450 ppm Zinc.
OP, to answer your question, look at the oil data sheets for actual viscosity, but most Castrol oils tend to be on the thicker side. Also nothing wrong with a 10W30 HDEO or a 10W40 PCMO. Both would be thicker than a regulat 10W30 PCMO.
That semi-synthetic MaxLife 10W40 looks good and would be worth a try, so would a low restriction oil filter.
