oil for fuel

[sandcobra164]

Quick question after searching to no avail. Does the NHC-250 burn oil as fuel in a mixture? I've got a truck who has stayed here for a while, it's almost out of Diesel and I've got some used motor oil to help fill the tank.

I think there is info in the Alternative Fuel thread about this.
My NHC 250 doesn't like much oil mixed in with the diesel.
Maximum 20% or it idles rough & is hard to start.

With no turbo to force air into it my guess is that the "nifty 250" would smoke like a coal fired steam engine if you go too high on the mixture.

Years ago a lot of trucking companies poured their waste oil into the fuel tanks of their trucks......that was before the computer controlled engines.

80-20 is prob the max mixture.

I am running 50-50 in my M813 with no problems. Starts good and runs good. Cant tell the difference except a little more smoke.

I would run straight diesel just to be safe...

I run a 80-20 oil to diesel blend. No problems so far. just filter filter filter!

If you are going to drive the truck you could mix it. If it just sits and you need to move it around once in a while, I would dump a few gallons of diesel in. You don't want to turn it into something that you have to push.

Keep in mind the compression ratio is not as high in the Cummins as in the Multi-fuel, so it may not do as well at higher mix rates. I run 20 to 30% WMO in my M818 but it's only in one tank and I don't switch to that tank until the engine is warmed up. I also switch back to straight diesel a couple of miles before I get home.
