New L/P operator with questions about minimizing costs

The Cummins X15 I have is rated at 450 HP at 1800 rpm and torque rating is 1750 lb/ft at 1000 rpm. I also have the Eaton Endurant 12 speed AMT.

 

Thank you everyone so far. I am going to try some.of the thing that were previously mentioned. One more thing. Will I get a ticket for impeding traffic if I cruise at 58 or 59 on the interstate? I know this has been asked before but I just wanna make sure.

 

Well, my dm pulled thru for me again. I got a load from Anderson SC to Brundidge AL that is less than 10000 pounds. I love these light loads. Better fuel mileage and less strain on the driveline.

 

This is just a general question but what do y'all think of the Detroit DD15? I had a Freightliner cascadia with it as a company driver and while it did get better fuel economy, it just didn't pull as well as the Cummins. It also had a DT12 as well.

 

Well, here is an update to my fuel cost minimization. So far, I have had one load that went about 350 or 400 miles. The load weighed around 11500. I busted an average of 9.0 to 9.5 miles to a gallon. What I did was use the cruise control as much as possible to stay at 66 mph until I got to long upgrades, during which I turned the cruise off and let the speed slowly fall to no less than 50 mph. Then I gradually mashed the go pedal. Coming down the hills, I coasted until I got to the speed limit. Now, I am on a load that weighs around 26000 and I am gonna see if the previous method works. If it does, fine. If I not, I will find what needs to be changed. In addition, I only put what fuel I need to do a given load plus maybe 20 gallons extra to make sure I have enough.

 

That's true. It also helps keep me from getting in situations where I have to brake hard to keep from rear ending someone. I'm starting to think why should I rush? Nothing I can do is gonna speed things up. So why rush?
