Speed and the Math

That extra 18 gallons of fuel(126 gallons) will mean an extra fillup that week. The 45 minutes saved (5.25hrs or 367 miles) per day could determine whether or not you picked up an extra load or sit for the weekend.

Time is more important than money. Manage it well.

 

70 mph = 6.5 mpg

65 mph = 6.2 mpg


Same engine...my truck

 

Good Job Varithms, it worked and continues to work for us....

 

While I do agree that running slower will net you more miles per gallon, on the majority of engines.

I have to come back to this...because something hit me as not being 100%.

You're saying that your truck losses about1.1 mile per gallon for a 5 mph increase ??????

Something is not right with this set up. And personally, I don't think it's the 5 mph causing that drastic a loss in fuel economy. I've never had that drastic of a drop in fuel consumption, unless I was constantly pulling hard mountain grades, running into a severe head winds, piss poor gearing, or running an engine that needed the overhead run.

 

Do the math for miles! Figure or guess how many miles in a year you will or want to run, divide by the number of miles per hour you want to cruise at. Yes I know this isn't real accurate for traffic etc., but a difference of 5 miles per hour over 120,000 miles a year is around 150 hours, or better than 2 weeks!

 

Fueling rarely takes me more than 15/20 minutes...Tops! Unless there a long line.


What takes you so long?

 

A BIG bladder maybe?

 

Oh......So it was him parked at the fuel island this morning at the Flyin' J in Lodi, Ca. while everyone was waiting to fuel!


Hmmmmmmmmmmmm????
