[QUOTE="KBMKVIII, post: 1558470, member: 5718"] I have yet to hand calculate so no real numbers. Was not easy on it during the trip home to help break-in. Was varying speeds, rpm and load consistently. Spedo reads 5 mph low due to tire size. Coming through the mountains the dash said 18+. Flat-ish with a 40 mph head wind New Mexico to Texas, dash said 15-16. As I start driving regularly, change factory oil fill and complete break-in I’ll have a better idea. [/QUOTE]
