X15 Oil Temp

[RByrd]

Kenworth W900L. We haul all over but mostly Southeast and Midwest areas. I get anywhere from 2 - 4 mpg loaded. Empty mpg just depends on how fast I want to run. With 4.30 rears, if I keep speed down around 60 mph, I can get around 6.5 mpg. However, even empty, I am still between 65,000 - 80,000 lbs empty depending on what trailer I have. Truck is new with no modifications. I have a boost gauge and I can monitor Exhaust Temp with the OTR tool I have. Exhaust temp fluctuates of course but I keep it under 900 degrees. Boost runs 31 psi at best.
