I agree with that. There's also the time involved. An engine that runs 180 for short trips for example, is worse off than an engine that runs 165-170 on longer trips. That's why I constantly say "it's all in the tune", because that's true. Were we live, it's about 25 minutes to the closest town we drive to, Gray. That's about the shortest trip we take. Otherwise, it's about 30 miles to Macon and the same to Milledgeville.
