Did some travelling in my 80, taking a week off to see family. Mostly asphalt, totaling 1100 miles looping from Peoria to Prescott, Flagstaff, Holbrook, St Johns, Springerville, Socorro, Las Cruces, Tucson then back home.
My point...I am really pleased with how the new motor is doing. About 8000 miles since putting it back on the road in early February 18. I've done a couple of long trips with the CSC crew (Mojave Road & North Rim) and a few other trips on my own. So far I've done three oil and filter changes and have no leaks, no issues, and no oil consumption at all. Average fuel mileage on this trip...14.76 mpg driving at posted speed limits. I did the math 3 times because I couldn't believe it! It seems that this motor likes to stretch its legs... I average 13.5 mpg running around the valley. Props to CBT on the engine rebuild
