Re: Interesting Fuel Article

Pretty much that says don't accelerate fast and obey speed limits......

Not trying to hate on your idea, because it does help, but you can't tell me that doing 70 in some cases will get better than doing 90.

Example. Made it from here to memphis in less than 2 hrs. We did 100 or so a lot of the way. The car got 23.7 mpg. On the way back went slower becase of less traffic, got 20. That was in the notch.

Hell, in the bullitt we made it from columbus to atlanta in less than 4 hours and got almost 27 mpg. Different cars have different efficiency ranges.

Re: Interesting Fuel Article

I can't really see how driving 50-55 in a 60 zone where most people are going 65 is very safe. Just causes more mess with people trying to pass the slow people, even if they are in the right lane. Better to flow with the traffic IMO.

Re: Interesting Fuel Article

I didn't read the article, but i think its supposed to have something to do with the drag increasing as you increase speed in a non-linear fashion.

Just remove air and lower gravity and we can get much better MPG.

has alot to do with the motor too. if you drive too slow in 5th and the motor is bogged down, you must use more throttle input to keep up speed. if you drive faster in that same gear and the engine is closer to its efficiency range you use less throttle input.

i know when i use 5th around town its like you can watch the needle go down because im bogging the motor at 1300rpm, and theres no acceleration to be had unless you drop two, i usually like to keep the 4.6 around 22-2500rpm if at all possible, and save 5th for the freeway. the above scenario is the patrol officer stalking me scenario.

Re: Interesting Fuel Article

I learned how to save gas on the way up to Tupelo last weekend...get in the slip stream of an 18 wheeler and cruise. The box ranger was cruising in no wind...it was sweet. I could also keep up with traffic that way
