GAS MPG

[nmikes]

on road trips I can get over 20 miles per tank... but that is with the tires at 40psi and cruise set at 65 cruising through Kansas. I don't know if it really makes a difference but I put the high octane in as well. Bombing around town I still get around 17mpg... but I never do any hard accelerating, braking, or powering through traffic. If you are getting single digit fuel economy something sounds wrong. I had a borla exhaust put on my F-150 and my fuel economy went to the ****ter... dealer said it was because the larger exhaust didn't provide enough back pressure for a clean burn. Don't know how true that is but I think hills and start and go traffic will put your fuel economy into the toilet with the gear ratios what they are. But there are people more informed on such things than I, I'm just hypostulating.
