What is the best oil viscosity to run in a 292 Inline-six with high miles?
My C30 has over 96k miles, and the 292 six under the hood currently has 40 weight Valvoline race oil in it, but it's time to change it out. I've had someone tell me that too thick of a viscosity may wear out the oil pump quicker, but I'm not sure. What's the best oil viscosity for an old engine...- Jonathonmb357
