additive needed for diesel??

I have never heard of doing such a thing and have run off road diesel in equipment for years you can add special stuff specifically for diesel fuel to keep from jelling up in the super cold and to provide a little extra cleaning power for the injectors if you want but I would not ad oil to it. Its called off road only because it is not taxed for on road use. hope this helps

Your friend's info is out of date...when low-sulfur fuel first came out, it did have lubricity problems, especially for distributor-type pumps, like Roosa Master. The other problem was that it leached the oil out of o-rings & seals, causing them to shrink & leak. That problem has been remedied, fuel suppliers caught enough flak that they added lubricity to the fuel. A fuel conditioner won't hurt anything, but it's not as necessary as it was for a while there...Your 504 (Case)? probably has a Bosch inline pump, which is not as susceptible to lubricity problems anyway.

The only additive I have used is a biocide to prohibit algae in long standing fuel most times you will not need. If you use any biofuel be prepared for major fuel problems had Ford F600 regularly change filter, three times clean fuel tank clean fuel lines etc. switch back to regular diesel no more problem. Currently work on D8 for Museum Fuel has been it for better than a year ( I like to keep it full or near full ) no problem, it doesn't get the work out it used to to much building around us but at least we are on leased county land so we are good for now. respectfully Gary

Yes, there is winter and summer blended diesel here in the US and Canada. Basically #1 diesel (more like kerosene) blended with regular #2 fuel to lower the cloud point.

Most of the time, the fuel suppliers take care of switching over what they are supplying, but if someone has their own large tank and is keeping lots of fuel on hand, they can get out of sync with the seasons and have problems. Usually there are lots of problems when exceptionally cold weather hits early in the winter and not everyone has a tank full of winter blend and has not changed fuel filters in preparation for winter etc. There are more diesel "daily driver" vehicles than there used to be, so lots of folks that don't know how to prepare for cold weather fuel related problems. If they are filling up at the local station on a regular basis, they don't have to know much about it. But, when it really gets cold, even the knowledeable diesel operator can get caught with gelled fuel/plugged fuel filter.

G'Day Gents,

Here in Western Australia, the fuel suppliers don't considder it cold enough, on average, to need them to supply winter fuel. So they don't...... It's not much fun for me, as I can go a week (with a few odd days thrown in here and there) where I can't run anything diesel at home. I just happen to live in a bloody cold spot. Nearly everyone else is fine. 😞

Newbie,
Just get some PowerService or something similar, a pour-point improver. Should help your summer fuel problem...or just add a little kerosene. Is # 1 diesel available there?

If you do doctor your diesel, make sure it won't invalidate any warranties that you might have.
