Just like the title says, my mileage has taken a HUGE dump! Before my trip to Ft Worth,TX in August to pick up the M-B I bought my IP busted. It was still pumping fuel and running the truck, it was just pumping alot of it out the hole in the side of the IP.
So I installed a new IP. The shaft on that one broke on the way home from getting the timing set by the diesel shop I had time it. Seems they left some bolts loose. It busted the shaft after 53 miles.
So I again installed a new IP & had it timed before I hit the road for my trip. It ran great for the 70 miles from my house to their shop, EGTs stayed below 1000* even pulling the long grades heavy on the throttle.
So The morning after I picked the truck back up, I loaded my aux tank in the bed and hit the road. I had loaded enough "fuel" to carry me round trip non stop with enough extra to allow for a 2-3mpg difference due to towing an '85 M-B 300D on the return trip based on my average of 16mpg prior to the IP problem.
Found out roughly 185 miles later that I was not in fact getting 16mpg any longer but was getting close to 10mpg. Doesn't take a rocket scientist to figure out I'm gonna be out of "fuel" long before I make it back home.(not a good time to find out that just because Tx has oil, does not mean they have cheaper diesel. IIRC I got it at the bargain price of $4.87 at the time)
So here's my question, is it possible that my IP did not infact get timed correctly, thus causing my dramatic decrease in mileage? One of the smaller voices in my head keeps telling me that the IP is outta time. I've even gone so far as turning the IP down to the point that maintaining steady speed on an average grade around here means putting the pedal to the floor.By doing so I have not gained enough increase to even bother mentioning. I want at least part of my mileage back, and ALL of my power back. As it is right now, the Bus gets better mileage than the truck does. If I can't change that, I'll be using the bus to pull my trailer,fetch lumber,etc.
To avoid confusion, all this applies to Smaug in my sig.
Sure hope someones got some ideas...I've run out of them.
