Mpg

Then I wager your best fuel mileage comes in 9th gear at ~1450. Probably ~50 mph.

 

Gearing is a big factor also. While my N14 seems to be most efficient at around 1400 rpm, 1400 rpm in top gear has me at 70 mph, not 60. This works out well for me, considering that all my loads are hurry-up deals.

 

I love mpg discussions, because I often pick up some ideas on efficiency. Also, fuel is my biggest single annual cost, so any percentage decrease has a strong impact on my net income.

Progressive shifting - it's more of a consideration for drivers who shift frequently. Cruising down some open road doesn't involve a lot of shifting, progressive or otherwise.

Driver's foot. Every time I get down to Laredo, I get a good shot of driving applications. Many of those Mexican drivers treat each red light, each stop sign, as a drag race starting line. It just doesn't make sense, for me, to beat feet up to the next light or stop. It wastes fuel, it's hard on my rig, and it's not really safe. Progressive shifting? Not yet, not in Laredo. Taking it easy, running up thru the gears with your foot not nailed to the firewall

 

Very good points. We drive thru a lot of small towns. Sometimes several stop lights in a row. I always look ahead at the next light or two, and try to time things so I arrive just as it is turning green. Not always possible, but it sure saves fuel/wear when you can make it happen.

 

Good comment, Shooter. Timing lights is a great way to drive, minimize fuel, reduce wear on truck, keep traffic flowing. Timing lights is an art form. My wife does not love it when I do it in my Silverado at home time.

 

Yep, same here. It's one of those things that's hard to un-learn.

 

Are we talking about the same thing on progressive shifting?

Its quite the opposite of speed shifting, aka the Laredo drag strip.

It works really well with floating gears up throughout the low and hi range on a eaton ten speed....

Here is an example....Eaton Fuller 10 /

Start in 2nd. Shift at 1000 rpm to 3rd
Shift at 1100 to 4th
Shift at 1200 to 5th
Shift at 1300 to 6th
Shift at 1400 to 7th
Shift at 1500 to 8th
Shift at 1650 to 9th
Shift at 1400 to overdrive (10th)....

 

You had me until this

 

I take you drive it like you stole it....
