So the suspense has built up long enough, its time we finally give you the rest of the secret diesel fuel mileage tips that Diesel Power Magazine ran in their October 2008 issue. Over the next couple of days we will cover some of our own diesel performance centered fuel mileage increasing methods as well, so be sure to check back for them. Let’s get on with the tips to increase your diesel fuel mileage!
23. Don’t Keep Tank Full: Remember that diesel fuel weighs about 7 pounds per gallon. Vehicles have a tendency to nickel and dime their owners to get some revenge make every pound count. Remember the straw that broke the camel’s back.
24. Remove Front Drive shaft: This easy modification drops the vehicle’s weight. It also makes for one less moving part on vehicles without lockouts. When winter comes or if fuel prices drop, put it back on.
25. Locking Hubs: Disconnecting the wheel from the axle with lockouts will improve .4 mpg.
26. Live on the edge and ditch the spare: This option will come more real once run-flat tires become an option for consumers. Still, tires today are so good the spare rarely gets used. We would guess that 3 times out of 10, the vehicle’s spare tire doesn’t have air in it anyway. In its place, have a few plugs and an old-fashioned hand pump. Craftsman came out with a 19.2 volt hand-held air pump that inflates low-volume tires up to 200 psi. As for plus, the ones from Napa are much better than the cheap ones. there is a big difference.
27. Look to racing: Now is the perfect time to upgrade to fiberglass fenders. Why stop there when you can spring for a carbon fiber hood? With fuel at the prices they are, one can’t afford not to.
28. Lexan: Replace as much glass as possible, although be sure to leave the windshield alone. Imagine what would happen in every pickup and SUV would replace just one piece of glass with this welterweight material.
29: Aerodynamic Tricks: Air dams and tire skirts push air away from un-aerodynamic areas. Early Broncos and many other cars from the ’50’s and ’60’s used tire skirts. With everyone’s attention focused on fuel consumption, we might see this retro styling return.
30. Manual Trans Swap: When shopping for a used truck, avoid three and four-speed automatic transmissions and seek out five and six-speed manuals, so your engine can stay in its torque peak.
31. Radiator Relocation: The mud bogging crowd has done this trick. With the radiator by the tailgate, the front could be totally blocked off.
32. Diesel Reinforcements: Propane, compressed natural gas (CNG), and hydrogen are alternatives in supplementing diesel.
33. Remove all traces of the air conditioner: This will make it cleaner under the hood and crate less load on your engine. Many serpentine belt systems can be routed with the compressor removed; all that is needed is a shorter belt.
34. Lower the truck: If you want big tires, get out the saw and cut the sheet metal. Don’t lift your truck anymore than you have to.
35. Fuel Connoisseur: Don’t fill up when the tankers are filling the tanks. Let the fuel settle before putting it in your truck.
Alright, now I am just going to come out and say that the bulk of these tips are just flat-out retarded, if you are so concerned about increasing your diesel fuel mileage that you are willing to remove your A/C and cut your sheet metal instead of lifting your truck you should be driving a ’95 civic and definitely not a diesel. Have any input? we would love to hear it.
