Excellent write Ramblin Red. These tips have another benifit. This rolling up easy to the stop signs and keeping the egg in one piece on acceleration is much easier on the truck. You are saving the driveline and the brakes. It is a win/win technique. IMO, you are ahead every time doing just as RR decribed.

 

I have to third that.
There is no replacement for proper driving techniques. Not only are these techniques proven to gain MPG., but also save thousands of miles of wear and tear on your rig all the way around.

These machines that we drive cost us a lot of money, and they are also how we make our money......treat them accordingly.
Seems funny to say that you have to handle and treat such large pieces of equipment with kid gloves, but if you do it will always pay you back in the long run.
Just my 2 cents

Agreed... hate to turn my Century in because it's just getting broken in nicely. I went from around 6.3 to 7.2 just working on technique. The only thing that I've really done to it otherwise is make sure the air-to-air clamps are good and tight, and the company has switched to much lower rolling-resistance tires. Finishing up around a 7.5 mpg average.

Keep a log of what you're doing!!!! It's about technique!

 

you need the whole package from pittsburgh power,turbo , engine control, muffler, bla bla
go to their website. if you change the muffler you need to have the engine contols reset to realize the most improvement in mpg.

 

Roadrunner can you report back it's being more than a month so by now you should have result .

Thank you .

 

I put the pittsmuffler on my Columbia 07 for weeks is a little more louder only my mpg is 0.5 better I have a c 13 with 2 exhaust iam happy with the mufflers before I put turbo 3000 and aircell in my truck only I lose my money with this.the best and the cheapest is the muffler I fixed in a shop in pa I 80 ex 29 only 55 us labor for 1 hour ,3 hours for 2 exhaust and works very good

 

Donaldson M100463 is the same muffler as the Pittsburgh Power muffler. You can buy them locally for roughly $100 at any Donaldson dealer

 

For my 2006 International 9400i, I removed the bug deflector off the hood, put in a resonator in place of muffler (my truck has side stacks and the muffler is under the frame), installed larger intake manifold, installed turbo blanket, and disabled the EGR. Usually run my ISX between 1350 and 1400 RPM which puts me between 62 and 65 mph with 3.42 rears on 22.5 low pro rubber. All of this has given me an average mpg in the mid 7's pulling average of around 36,000 in freight in a 53' dry box. The mid 7 fuel mileage is based on pump to pump on paper. According to the computer, the mileage is actually in the low 8's. Shows how much the computer can be off.

Like was mentioned here, I watch the driving techniques a lot. No jackrabbit take offs, I ease off at the top of a hill and let the momentum carry me over and the downhill get my speed back up, acting like there is a "rotten egg" on the throttle pedal, progressive shifting, keep idling to a minimum, etc.

Have given consideration to removing the side stacks when it comes time to redo the exhaust and running a single pipe up the back. Mostly because I can't stand fighting to look around the darn things when backing and getting them off may actually streamline the aerodynamics a little and help with mpg. Still debating that move at this time. Oh, I suppose it may make the truck not look so cool, but a truck is a tool to get a job done with the least expense in doing it. I only got this one with stacks because everything else about the truck was spec'd pretty close to what I wanted. Figured I could remove the stacks if the time came.

 

I don't understand why you would run such a tall gear if your only going to run 62-65 mph, if you dropped the rear gear you would take some strain off the engine and get better mileage. I was getting 6+ in my log truck running 4:33 and running on the floor most of the time. Also, ran it at 70 which is 1800rpm. Of course, we run 24.5's.
