Driving on highway with lights

It's all about progressive shifting for me. Ramming and cramming the gears does nothing for MPG's. I try not to go over 1500 RPMs at any time. Also, if there's a series of lights, I won't even try to hit the speed limit. Everything I do when driving revolves around fuel economy. I reckon that's why my '97 Freightliner Classic with a 470 Detroit and Eaton 13spd gets 6.3 mpg.

 

The same answer applies. The lower the RPMs, the higher the MPGs. Slow and easy is where it's at. Ramming and cramming getting to the speed limit as fast as possible will not net you MPGs?

 

The Torque you use must... the horsepower not.


* Use the Torque

 

I've heard of this theory, getting to cruise speed as fast as possible to maximize time spend cruising instead of accelerating. The theory is that since you get best mpg when cruising you should try to maximize your time cruising. But I don't think it works in real life. The extra fuel used to accelerate quickly will be more than what you'd save from the (little bit) of extra time cruising instead of accelerating!

I think this theory was thought of by some leadfoot as an excuse for his/her driving!

 

Get to speed as slow as possible, treat the go pedal as if there is an egg under it. Watch the boost guage, it is as close to a mpg calculator as most trucks have, the less boost the less fuel burned

 

I believe this only applies to cars. I read a recent study that confirmed this - that getting up to speed as quickly as possible is more efficient but I do believe it's ONLY for AUTOMATIC cars. I still don't do it but that's what the most recent "people" say. Who knows?
