    Thoughts on the 2015 Duramax's

    LMM: Regen issues

    Not Sure I have been told that if you drive it in tow haul mode even if you aren't towing anything that it will straighten up. The guy told me to do it about once a week. He said that he had success by doing this. We were just talking. I didn't have a problem. It might be worth a try. Good Luck.

    LML c tane rating

    I really wasn't worried as much as I was curious. Logic tells me that if a company has to refine or put in additives to attain a higher c tane rating, then the cost of doing either/or would be less for a lower c tane rating, thereby allowing the Gasoline companies a larger profit if they just...

    LML c tane rating

    In my reading about it. I think most are 40-55. If I remember what I read, California has a minimum of 53. The article said the higher the C-Tane rating, the better the Diesel performs. But I think that Bio-Diesel will have a higher c-tane rating. Correct me if I am wrong. Thanks

    LML Dpf

    I have a 2015 stock lml. It has 4000 miles on it. I have never seen a regen message. I have been told by the dealer that it is probably doing light cleanings and not to be concerned. If that is the case they say I may not get a message. Does this make sense? I did get a add def at about 1600...

    LMM DPF regen

    I think the 2015 Trucks show a Text message in the DIC saying that it is regenerating. At least that is what the book says. Don't think there is a light. I did find out there is a recall on "Power Steering Hose Clamps Inspection" And " They had to re program my puter because there is a glitch in...

    How are the LML's holding up?

    Lml :)used to have a 06 Duramax LBZ . Went back to 6.0 Gas in 2013. Huge Mistake. I just bought a 2015 Duramax. I only have around 900 miles on it but so far I love it. It is even quieter than the 06 was. Too early to tell about mileage but it is one heck of a truck.
