Check out some of the Mastercraft options..Good cooper made tire for a little less coin. We've ran numerous sets on our old dodge 12-valve farm truck...
I understand that trucks have ran on dino for millions of miles, this one included. He is just wanting something that is going to hold up in extreme heat more so than the delvac he was running. The spun bearing was due to an oil cooler malfunction & he was just wanting a little more protection...
A good friend of mine just had the motor rebuilt in his Freightliner after a spun bearing. We sell schaeffer's at the store and I'm trying to help justify the cost to him. Would he see a noticeable oil temp decrease running schaeffer's 5w40?
I agree with the previous recommendations. My mother-in-law had a 99 accord i fed a steady diet of trop artic 5w30 & had 387k on it when she donated it to the local battered women's shelter, still see the car around town from time to time..
