I've asked this question within other threads, but never really received a response, so I thought I'd try it here

.
Question: Optimum gas mileage- am I correct in my thinking that while towing at the rpm in which the horsepower and torque curves intersect is where one would get their best gas mileage?
Mine intersects @ 2500rpm, which translates to 55mph in 3 gear. At this speed, rpm & gear-I'm getting 13mpg.
So if any of you engine gruru's could set me straight, I'd be greatful-John
