DEAN M.

"The engine runs great so far, but we haven't gotten it fully broken in yet. So far it is getting 22mpg highway and no smoke. EGTs are nothing to worry about at all even when towing. My son was impressed we were getting 18mpg running over 80mph across Utah. I will be happy to keep you updated on mileage and performance once the engine is fully broken in."
