Howdy all,

I know I've read here that kerosene is a no-no...but why?

Lack of lube-type property ?

Could it be used with extra fuel treatment?

Would it be better or worse than burning bulk veggie-oil? Like the stuff that comes in 5 gallon cans.
I know I can't burn veggie-oil in the winter,but if I can suppliment my beasts thirst in the summer without hurting the injectors,what the hey....

Around here diesel is going for near $3 a gallon ($2.93-7/gal),but I can get kero for $2.29.
If it's going to hurt the VE I won't even think about it...but if not...

I talked to a guy who has been burning 5 gallons a tank or so in his dufa-max for the last year without any problems so far...and it got me thinkin'.

Thanks in advance,

Vinny

 

I think that you can run a Cummins on straight kerosene if you wanted to, couldn't you?

Vegetable oil, at least what is commonly known as vegetable oil, has a higher cetane value than #2. Kerosene has lower.

So the kerosene would cause you to loose power. Veggie causes you to gain power*.


I don't think that the lack of lubrication would really hurt the 1st gens, since we use oil-lubed pumps. I don't know about a Duramax, though.

So even if you could do it, why would you want to loose power?

I say plumb up the truck for veggie oil and get it for free. I have a shady deal with a greasy spoon in town for 70 gallons of good fryer oil a week, for 1.00 a gallon. Of course, I'm too lazy to convert my truck, but neh...

*In thoery. Veggie oil sure seems to run better, that's for sure. But I've never seen a system on a Cummins.

 

the first gen will run on kerosene, just add 5% oil to it. the first gen injection pumps rely on fuel to lube them.

 

Really? I thought mechanical pump= oil lubed pump?

Show's what I know...

 

Yeah, you can run kerosene, but the fuel mileage will suffer. Dump a gallon of waste motor oil in with the K1 and you will restore the lubricity. Fuel mileage will still be down, but if you can get K1 for 70% of the price of #2 you still come out ahead.

 

The VE rotary pump is lubricated by the fuel that runs through it not by oil from the engine. The P7100 on 2nd Gens uses engine oil for lubrication. If I were going to use kero I would use something like Stanadyne Performance formula - which will raise the cetane level.

Yip, lubed AND cooled by fuel....two GOOD reasons to use an additive in your fuel ALL year 'round...
