This is a brand-neutral oil question. I'm hoping folks with extensive high-performance experience can chime in with useful info.
The Cummins B-series requires 15W40 oil for ordinary operational usage. I don't know what the Powerstroke and Duramax require, but I would think it'd be quite similar.
The question relates to high-HP racing/pulling operation. Given that the 15W40 oil provides a cushion of oil on which the moving parts ride, at what level of torque/HP does 15W40 become too thin to provide adequate lubrication?
Considering that drag racers often use 20W50 in their engines, it occurred to me that perhaps the high HP diesel guys might want to consider increasing their oil viscosity. Or is this question of viscosity in performance diesels a non-issue?
