    Question 305,000 miles on the original set!

    Ok............... I have a friend here with a 2002 DMAX with 305,000 miles and the injectors are the original set! Question........ who is a good aftermarket source? GM injectors are $269.50 each plus $125 core. Since I am a dealer tech, I don't deal with the aftermarket stuff. Any help here would be great.

    (Duramaster please check the Medium Duty forum for my thread on C4500 cold high idle function - and a few others I could use your insite on.)

    Thats amazing.
    • Any additional fuel filtration?
    • Any regular use of fuel additives? What brand?
    • Where did he buy his fuel?

    I am betting that he bought fuel at the same place most of the time - and they had good, clean tanks and went through a high volume of quality fuel.

    I am convinced that the reason the C4500 only got 43K on the first set of injectors had to be related to all the random fuel it gets while on the road nationwide, and in Canada. Just one rust or sediment laden tankful could do in a set of perfectly good injectors. I think it was a tankful purchased in New York or New Jersey. The wisps of smoke at idle started after that trip, and only got worse over the next 3K miles. (Sorry to all you east coast residents out there... )

    Since this is unusual, lets figure out WHY these injectors have lived so long! The info could be useful.

    ok ok.............. I am truly sorry for the lack of effort on my part Mark......................I think about that CAC everyday, but I keep forgetting to ask the parts guy. What exactly do you want to know about the CAC anyway?


    AS far as the 305,000 goes. The truck was traded in at our dealership (SMOKING). Our wholesaler looked at it at about 248,000 and it wasn't smoking then. The owner just did alot of highway driving up and down the I-5 corridor. Evidintly he decided to trade it off when the smoke started. The wholesaler is only asking $13,500 for it. It is in really nice shape. I might actully get to make a little money on this one!

    So it sounds like lots of highway miles was one factor...that price seems high for the miles. Good to know they are holding value later in life. I consider my '02 with 240K to be a 8-10K truck, but it is definately a 'work truck'.

    (Lets discuss C4500 specific topics in the Medium duty forum.)

    Default My Injectors

    I'd like to chime in. I'm turning 270,000 miles on my '02 and just replaced the injectors for the Seventh time. Last two times was on my dime. The shop got these last injectors from a Chevy dealer in Houston for $290 each. I replaced the dual mass flywheel with a single piece from South Bend Transmissions and I cant tell any difference.

    I would (almost always) fill up at Flying J and add a dose or Stanadyne Diesel Sup to the tank (4 oz per 30 gals). Still the injectors would fail.

    I now use Bio Diesel from Canola seed from a place in Ralls TX (just East of Lubbock). Since I have a 115 gal tank in the bed, I ran about 600 miles on B100 (100% bio) changed filters twice and now run somewhere between B20 and B40. I'll fill the regular tank with 30 gals of Petrol Diesel and add enough Bio to make it B20 or B40. The Bio is about .20 cents cheaper than petrol which is nice and the money goes to our farmers instead of them #*@%!!! foreigners.

    I usually drive about 10 to 12,000 monthly but will take it easier till January when the RV business comes back to work.

    Buy the way, I have a case of FPPF from John Kennedy and will use it instead of the Stanadyne for a while. John's a hard salesman
