Took the Truck to the shop today and they ran the computer on it and nothing showed up. The fuel mileage showed 5.46 avg. I told them it was above that when I bought it 9-28-07, and that I had been avg 6.0.
They reset the computer (Cost $90.00 Labor to do this) Guess they have to make money, but not this much!
Requested they take an oil sample and send it off and see what it tells me if anything.
Service MGR said they could run overhead, but he would run it 1 more week with the computer reset and see if it shows the 4.4 avg.
Was told that I could have got some ultra low sulphar fuel, and this could cause the big drop.
Where I fuel most of the time has the low sulfur sign but not ultra low. The place that I got fuel at and it started dropping, I am not sure if it is ultra or not, but will find out.

buy fuel somewhere else
see if there is a difference
(may be bad fuel or someone tampering with the pump?)
dump some diesel clean in to boost cetane
see if that makes a dif
are you sure your odometer is accurate
lock your fuel cap
Odometer is correct as we on a pay per ton by mile, so the places I go have distances already set and I check it to make sure I am getting my pay right.
If I got some bad fuel could it cause the following on mpg. Starting on
10-14 I bought fuel at a different place. Before that here is the fuel mileage avg:
10-3-7 411 miles 72.28 gal 5.68mpg
10-8-7 477 miles 81.17 gal 5.87 mpg
10-13-7 491 miles 83.15 gal 5.90 mpg
Switched vendors
10-14-7 666 miles 116.02 gal 5.74 mpg
10-15-7 655 miles 119.00 gal 5.50 mpg
10-16-7 654 miles 125.70 gal 5.20 mpg
Switched back to original vendor I have used for the past 6 months
10-18-7 562 miles 106.99 gal 5.25 mpg
10-19-7 327 miles 73.02 gal 4.48 mpg
Hope this will turn around soon!
Anyone have any suggestions that have not already been posted, I WOULD greatly apprecaite it very much.
