    Hi everyone, Wondering what peoples opinions are of the 505HP DD15 engines? I’m looking at a 2017. I don’t haul heavy, but this truck looks like it has been well maintained by the owner. Wondering if Its any more problematic or less problematic than another engine. Thank you

    I own 2 in western stars. one has 872k
    The other 316k
    No real issues, I am very proactive on maintenance and do not take chances I change parts before life cycle of said part is up. But neither has ever broke down or given me an issue.
    Neither truck gets idled for very long
    Def filter gets changed yearly, sensors in one boxes get pulled yearly and cleaned
    And coolant gets dumped at 300k
    And coolant pumped changed at 300k
    Mostly due to a lack of coolant filters on
    Newer DD15.
    They are a good engine Life time average on one truck is 7.25 and my truck is 7.31 mpg with 4% idle time.

    The one I am looking at is sold by an Owner Op who has owned it since 300k Miles. Its got 500k now and he put 200k in 3 years. I just don’t know if 505HP engines are prone to breaking down more so than less HP

    Find out if it was a 505 from birth, and not just turned up to 505.

    He bought it from Freightliner used it was in 2018 with 290k miles. I doubt Freightliner bumped the HP up. He didn’t for sure.

    Just look at the sticker on the top of the engine. Or get freightliner to run the Vin.

    Messing with settings is the path to woe.

    If it was born a 505, then how you care and drive it will be 75% of how well it lasts.
     
    AlexD13 Thanks this.

    Called the dealer and they said its Rated 440HP. This guy did change the Govern speed to 74 so maybe thats when it was changed. So do you reccommend I stay away from this truck? He has 10,000 engine hours with 480k miles. Hes got an APU
