WMO

[Walker111]

I’m interested in using MY WMO in my 12v. I currently drain my oil into a clean 5gal bucket, then gravity feed it thru a Baldwin BT389-10, then thru a Baldwin BF7633, then to a clean 5gal bucket.

I’m not looking to run a full tank of it, just 3-5 gallons with a full tank of fresh diesel.

If this is gonna coke up injectors or kill the P pump, I’m not interested.

TIA

Jim

Jim, I did that very thing back @ 15 years ago when fuel was so high. Don’t know that it mattered, but I only used conventional oil no heavier than 10W40.

I worked at a large motorcycle shop and had access to a lot of clean used oil. All the techs were very helpful, using only the new clean drain pans I brought them and not mixing other fluids with it. I had a clean plastic drum to store it in after filtering it and a barrel pump with another filter on it to pump out into a fuel can. I’d run 5-gallons oil to 20-25 gallons of diesel. When I removed my injectors after doing this for @ 50K miles there was a very minimal amount of “soot” on the tips. I took them to be cleaned and pop tested and the fuel shop said they looked great.

I've been doing this since the late 90's on a few different trucks with no issues. I never bothered with filtering until around 2006 when I bought a transfer tank and put a filter on it. I just made sure I drained my oil into a clean container and dumped it in. I always tried to keep the mix around 10% or so to keep the smoke down, but I've had it as high as 25% a few times.

It is really very bad for the environment but technically it is okay.

Ozy, I believe that's the first thing you've posted I don't agree with.

Thanks guys, I appreciate the feedback.

@Ozymandias, Doing this is on line with the waste oil burners that they market to everyone with a garage or large workshop! I know of several farmers with older equipment that does this and the waste oil burner for shop. He collects the oil from all his stuff into a large transfer tank (oil only), then moves it to where he needs it. Clean trans fluid goes straight to burner tank. Has filters on transfer tank and the burner has 2 filters on it before it hits the burner nozzle. Wish I could do with mine, not sure how the newer trucks would do with that mix. Would help a bit with fuel cost!

I wouldn't do it in anything but a 2nd Gen 12-Valve.

There is a difference in WMO in an engine vs a burner. The varying loads in an engine can get the combustion temps low enough to not allow the WMO to burn efficiently, which increases emissions.

Under a moderate to heavy load the WMO will burn efficiently.

That is the reason I always tried to shoot for 10%, any more than that, I would start to notice a constant haze until I got up to operating temp. I never kept track of how many gallons of WMO I've burned over the last 25 years, but I'm guessing I've traveled for tens of thousands of miles for free!

 

[Ozymandias]

The problem is pollution through all the heavy metals in the WMO. You all know what's in the oil through the oil analysis results.
WMO is banned to use as a fuel for whatever throughout Europe for more then 30 years because of that.

So is running a modified Cummins.

IMHO you can run one quart clean used motor oil per tank without any side effects on a 07 and earlier Cummins.

What good is a quart going to do? The point here is saving money on fuel. Five gallons of free oil takes the place of $25.00-$30.00 of diesel.

Same result just takes longer. No way would I dump 5 gallons at a time in a 35 gallon tank.

No, I wouldn’t either in anything other than a 2nd Gen 12-Valve, but as I said, I’ve done it for many miles with no issues in my 2nd Gen 12-Valve. I definitely wouldn’t put out all the effort to save a buck and a quarter per tank by adding a quart to a tank.

That would be one smoky MoFo

my 75 kw had NTC 350 cummins and held 44qts of oil when i changed oil 44 qts went in left side 100gal fuel tank never had a problem

I did up to 5 gallons a tank with my ol undervalved Cummins, no ill effects.
