15ppm (Parts Per Million) ultra low sulfur Diesel has lube built into it. I run my Mercedes Turbo Diesel (1984 with almost 500k miles) with no problems.
When I first started to drive for Bekins in 1985, they sent me to Rhinelander, Wis in winter. I had added Diesel Power Service to the fuel. I checked into a motel that night and shut down the engine (8V-92TA)-wondering why the truck next to me left his truck running with his tires blocked. It was -20f in the morning. The engine turned over slowly. So I jacked up the cab (mostly cabover's then) and sprayed ether directly into the blower (was a plug on the intake at the blower for exactly this). After two tries, got the engine running. Now getting the brakes to release-that was another 2 hour adventure. Live and learn-now I know why the truck next to me kept his engine running with his brakes released and tires blocked. Good Luck, TomC

   Hi all;
       I understand on this blog, that today's diesel fuel will go "bad" after
       awhile like gasoline.  How long does it take for the fuel to become
       questionable?
                                   Merle.

The new fuels also have 'oxidizing agents' added to help it burn cleaner - which reduces shelf life.

other things influencing the useful life of your fuel will depend on how much moisture it is exposed to - and the temp swings - dew points - etc

New fuel systems are sealed - old ones are vented to atmosphere, so fuel will last longer in new systems vs old.

Bottom line -- it is best to use it before it gets too old  ;D

Tim -

Another tip - keep the tank full to keep condensation to a minimum.

I try to fuel in the morning when traveling.  If I'm going to be parked somewhere for a few days, I wait until the morning that I'm leaving.  That keeps the fuel in the tank fairly fresh, further reducing the risk of fuel issues.

I use gasbuddy.com to find fuel, but try to avoid stations with B20.

I also never go more than 500-600 miles without fueling to avoid running out.  Even tho I've got a 144 gallon tank, I only plan on using 100 gallons before refueling, because repriming the Detroit is a PITA!

FWIW & HTH. . .
