If you had a 454 with 40k on the engine, would you stay with 15w40?
The guage shows 30 psi oil pressure @ idle hot and 45/50 down the road
It depends, is your 454 fuel injected or carb? Open plains driving or mountain passes? In AZ I'd probably lean towards the 15w40 if it has a carb. I agree with the others that if it holds good oil pressure on 10w30 than that will also be sufficient.
