    Just bought my first diesel engine. Got a 2500 duramax and I've never owned a diesel before.

    Anything I should know?

    Difference in diesel fuels? Don't buy from discount gas stations etc. ?

    New truck or old truck?

    Older ones like my 2003 need additives in the fuel to work long term with today's low sulphur diesel. Just buy plain ol #2 diesel at the station.

    If you bought a new truck they have all kinds of shit in the system for emissions, can't help you at all there.

    First thing is buy clean fuel and keep it clean. Do not put it under heavy load until the engine temperature is near operating range.

    I would recommend using a fuel additive to make sure the high pressure fuel pump to make sure the fuel pump is adequately lubricated. I use XPD in my Dodge.

    Use a really high quality fuel filter and high quality oil filter. Change the air filter and keep it clean.

    I used to run a tank/month of bio-d thru my PSD to keep things clean. While the exhaust didn't smell like french fries, it didn't smell like diesel either. :thumb

    Power service is your friend. Stanadyne is better, but more expensive and harder to find. PM Triple. He'll sell you a case. Did for me!

    Gloves while fueling. That smell don't come out of your hands very quickly. :eek1

    Otherwise, its an engine...

    Speaking of Triple: he owns/runs one of the best diesel shops around. GREAT guy to know if you've got a diesel. A great guy to know especially if you're driving a Dodge.

    The grey bottle is more betterer...:lol3
    FPPF supposedly beats 'em all, but I've used grey bottle PS since '99 in 3 trucks and never had a fuel related issue.

    www.thedieselpageforums.com is your friend if any issues arise.

    Use only #1 diesel, the #2 diesel that most stations sell is junky thicker diesel that will ruin your truck. If you can't find #1 diesel near you, just run premium gasoline with power service additive every tank.

    Or something like that.

    I know it's Ken, but this is Shiny Things, not JM.

    Ken,

    Two things to be concerned about are the cetane rating and wear scar rating of the fuel. U.S. diesel fuel is notoriously bad in both ratings, so that's why the suggestion of additives.

    Make sure you grab the diesel handle at the pump...

    Sometimes they're yellow, or green, or black, or the same color as the gasoline handle.

    I think the old Caterpillar tank caps used to say 'buy clean fuel, keep it clean'

    when my wifes truck was new and only had a 40k miles on it she put ~ 17 gals of regular gas in it and drove it like that. that was about 400k miles ago and we can't really tell much differnce. She got pretty near the same mpg on that tank as well.

    we know of few people with over 400k on thier trucks so we can't really compare.

    #1 diesel is for when temps will go below about 35F as #2 will gel at about 25F other than that it has no advantage. We have never used any of the additives in our truck and between the 2 we have over 750k miles with only a clutch or 2 and other minor repairs.

    As a disclaimer she had 425k on a VW vanagon waterboxer. She did have that motor rebuilt a few times.

    edit as someone else said buy clean fuel and keep it clean; your fuel filter is more important then your oil filter if you are not pulling over 5 tons with the truck.

    How do you know where to buy "clean fuel" ? The cheapest place around me for Diesel is a RaceTrack and it's at $3.74 a gallon. How do I know if it's "clean"? I'll replace the fuel filter at every scheduled service but should I replace it more often?
