I'm wanting to know if used in a gasoline engine, is there any reason to run a low SAPS oil? Pretty straight forward, I think.
In a naturally aspirated, non-DI engine, is there a reason to run one oil over the other?
Actually, the truck will be used in a variety of ways. 10-12k miles a year with short commutes to work, pulling a boat and a trailer, etc etc
But nothing crazy severe, like a tri-axle race trailer pulled through the Rockies
