Fuel mixing....

Have been experimenting with mixing fuels in my diesel including yet not limited to; gasoline (up to 5%), kerosene (up to 10%), veggie oil (up to 50%), waste oil(up to 10%) and etc.

None seem to make any difference. Here's a crazy idea: Farmers for years have been adding fertilizer (high nitrate) to diesel to remove stumps, blow rocks and etc. What about adding just a tad to my diesel fuel? If it was done in reason wouldn't that give me more power/economy?

Mercedes is adding uric acid (nitrates?) downstream in their new Bluetech with I think better combustion in mind. Of course I wonder where the uric acid has to come from or does one wee in a tank at fill-up?

Just some thoughts crossing my mind yet I'd love a real response, thanks, Mark

RE: Fuel mixing....

As a fellow ‘mixer’ I’d say stay with the tried and true stuff. I’m a big fan of used motor oil, for example. I add about a gallon and a half to a full tank of diesel. A little RUG is good with the WVO, and kerosene is good when it’s cold (not a problem for me.)

It's way downstream and it's intended to control emissions.  

They will actually have an on-board tank to dispense it

Needs replacing at some long-term interval..  I believe it's next year's 50-State version btw

RE: Fuel mixing....

Used motor oil? Do you filter if a bit before pouring it in? Does it smoke horribly? Your pre filter and main filter must get dirty in a hurry.

Mark :err:


I use a 5 micron bag filter. There is no smoke at all and the filters are replaced at the normal intervals.

Anything smaller than 5 microns will remain suspended in the fuel; Something that tiny can't damage any of the pump components.

Re: Fuel mixing....

ill keep that in mind, my boss's old father told me about how they have old Mercedes LKW's (big trucks) in the BundesAbWehr that will run on anything (60's models years), even straight old motor oil..........i just didnt think it would be ok with the pump.........

Sounds like you really enjoy abusing your engine. Let's hope you don't decide to get another one to abuse when this one dies.

That can get you some time in the federal pen....driving aroujnd with fertilizer and diesel in a tank.

Think back to the Oklahoma city thing.

 They do not use uric acid, they use urea which is man made from ammonia and carbon dioxide. It also does not affect combustion in any way. It's injected into the catalytic converter to increase it's efficiency in removing NOx from the exhaust fumes.

Thanks,

I too had thought it a discussion forum not a critique forum, oh well.

We have a few members with too much of an edge. 

But we err on the side of freedom around here

Even if that freedom involves the use of illegal fuels.

Re: Fuel mixing....

Sorry anybody found my discussion of experimentation offensive. For the record it was just an experiment not a practice. Actually, even at $5 a gallon mixing fuel is just too much of a hassle and risk. Thank you.

Well, you're still here, that at least proves you didn't blow yourself up

Re: Fuel mixing....

Would never have added enough to cause a blow up. Interestingly enough, Sunoco or Shell is now adding Nitrogen to fuel to improve performance--all I was trying to do. Will be interested to see if this catches on with the other major oil companies. However, ignorance will probably prevent most from understanding even elementary chemistry and hence the benefit. Happy motoring!
