low sulfer fuel, what's it mean for us?

[John - K5AWO]

Got concerned that no sulphur equals dead VP44. (pun intended but can be all too true)



Dumped in 10 gallons of 10-40 filtered crankcase oil to 30 gallons of diesel. Bed tank holds 50 gallons.



My truck seems to have more torque between 1000-1800 rpm and the transmission is shifting nice and firm ... and... I am using less go pedal pressure.



I read that oil is more dense than diesel fuel. Must be what did the trick. My son and I noticed the same effect running veggie oil. His truck is the same as mine.

Well, ya get GOOD marks for trying to improve lubricity - but USED motor oil is certainly not the BEST way to get it...



The subject of recycling used motor oil has been covered here many times, with some references as to some of the big rigs that do it - but most, including me, figure there are enough decent fuel lubricity additives available on the market at a decent price specifically designed for use in fuel to not use contaminated materials not really best suited for use in diesel fuels...

 

[RustyJC]

Most diesel engine lubricating oils are high-ash - > 1% sulfated ash content due to their additive packages. This will promote combustion zone deposit formation.



Your $$$$$ - your choice!

There's a lot of dissolved solids in used oil that you can never filter out. They will become solid in places like injectors, piston crowns, exhaust vavles, etc. This can include lots of nasty stuff like heavy metals. Not worth burning it in a good diesel.



I've burned it in a wood stove and it causes enough problems there!

John E:

yes, you are correct with the sulfur as not really a lubricant 'technically' but the process of removing it removes the fuels natural lubricity. (along with a tendency of ruining nitrile seals ). And yes, I would use lubricity additives until the fuel gets to atleast <300 um or so. My argument w/ the P pump was the point of highest stress.



Of course, since the first post, it is advantageos to remove it, and have the fuels lubricity way up there at the same time. Preferably with the price way down there too, but currently it is expensive (atleast at first due to equipment) to remove the sulfur.

Monty sent me an interesting pointer a few others might be interesting reading - especially the West coast guys, and by that Wattenburg fella...

Burke Oil has ULSD Diesel at the pump. Maybe someone wants to try it and see how it is? I wonder if it burns real clean? The TDI guys seem to like it. Smells like jet fuel and burns CLEAN.

ULSD Spec Sheet: http://www.burkeoil.com/pdf/ulsd1.pdf

We are useing ULSD at my job and it is working out real good . We have a F-Series Ford with a Cummins in it and it runs just as good as it ever has -------------- well except for when we were running that trashy diesel water mix Purinox junk. It does cost more and the engine is stock , don't know how a bomb Cummins will run on it thou .

 

[metwuk]

First of all, ULSD will not be "watered down" with kerosene/jet-a fuel which are for the most part the same. The sulfur content in k/j is up to 2x+ higher than the current low sulfur diesel fuel!!

 

[Blakers]

That's good to know.
