I use a 2009 Chevy 3500 LMM 6.6L Duramax for expedite freight delivery. I'm looking for any advice I can get for squeezing every ounce I can out of my fuel.
Engine/tranny longevity and better MPG are my only objectives. My truck runs smoother, cleaner, with lower EGT'S, lower oil/coolant/tranny fluid temps than it ever did stock. I run my truck everyday with 10-4000lbs. in the bed only-no trailers anymore.
I've owned a small trucking company hauling frac sand with a pneumatic trailer, hauled cars with a double deck trailer, flatbed and even hauled enclosed trailers. Keeping engines up and running with a quick/eventual ROI was a must, not a bonus.
No matter what some people think of us in the trucking industry most owner operator's are environmentally responsible individuals working with slim profit margins struggling against ever burdensome regulations. Data is often fed to the public that is misleading or down right dishonest! Every % of gains in MPG means we can pay our bills the next month. For most trucking companies the taxes/fuel alone run around 70% of gross. We work with 6% usually to keep going.
Although I no longer own nor drive Class 8 vehicles I work closely with them daily. I've learned more from these men/women than I ever did in college or in the "Professional" world. Its crazy the things we go through just to keep your shelves stocked.
I say all this to bring home the point that MPG, engines that run clean and forever are paramount to our survival. 1/8 of a MPG saved to us (although hard to calculate) is looked at as one thing only "an improvement"
Mpg gains turn into $20,000-$30,000 a year reclaimed! Easily!
I will gladly consider ANYTHING to help improve MPG gains or tips/advice/experience for engine longevity or efficiency gains.
I will also gladly share or collect any data I can.
Amsoil by pass <> Auxiliary fuel filters <> Guages 4 everything <> Synthetic fluids throughout <> AFE Intake <> Intake tubes <> Kennedy Lift Pump <> EFI Programming <> Deep Oil & Tranny pans <> TransGo Shift kit <> Upgraded Fuel lines <> Data Logging analysis run weekly, monitored constantly <> Engine trimmed of unnecessary parts <> Shell fuel ONLY <> Oil Analysis monthly
If you don't already use synthetic oil and other synthetic fluids, switching will definitely get you more longevity, and in the long run fuel savings too. In my previous experience with heavy duty diesels, that if the fuel filter wasn't changed at least every other oil change, that driveability problems came up. If at all possible, avoid excessive idling too.
