I had the EGR and Oil cooler replaced last year. I have not had any issues since the work was done. I change oil every 5k religously and it was flushed correctly after the work was completed. I get a very decent 20 to 22 mpg cruising interstate at 65(it seems my truck likes 65 better than 70 for mpg). The trailer is an open flat bed with the tall ramp gate with wire mesh so it seems that would allow air to pass thru (my thinking when I bought this trailer anyway).
The loss of 20mpg to 12mpg seems extreme. The trailer tracks true and I have packed bearings so no issues there. If I am getting 12mpg empty I am scared of what I will see when I load 2 fullsize bikes on it.
What is crazy is I pull a 40 ft 5er and get 10 or 11mpg and that weighs
That rig sounds almost like mine, I have a mesh gate on the trailer too, same mods to the engine, stock tune, stock exhaust, tires stock size. And yes, my best on an unloaded cruise truck alone 65-70 mph, was 22 mpg. Something doesn't sound right.
