6.7 Going to DEALER tommorrow....

[Doughboy21kd]

And it's going in cause my "OIL CHANGE REQUIRED" message comes on every 1300 miles or so.....



And when i change the oil i put 1qt in filter and 11qts in the pan... .



Also cause my mileage is NOT GOOD..... There thinking that may be caused by going into REGEN TOO MUCH.....



With all that being said what are the TSB #'s i need and what is the most recent Flash i need?



THANKS ALOT

I had my 6. 7L computer recalibrated yesterday. The TSBs are pulled up by VIN. If your complaint matches a TSB, they recalibrate the computer. They updated my truck using TSB#18-033-07 and OP#18-19-04-35. The oil change frequency is determined by the engine computer - don't let the dealer just reset the warning light. This oil change notification feature was not supposed to be on the 6. 7L until 2008. My dealer was not aware of it, until I told him. The harder you work the 6. 7L the more miles you will experience between oil changes. If you do a lot of stop and go driving or idle a lot, the result will be less miles between oil changes. Love the truck! Fred
