peanut oil

I have a source for used peanut oil for my single tank conversion. Any yeas or nays?

It will work....peanut oil is of excellent quality...probably the best you could use short of olive oil. Hopefully your system is a proper setup and won't destroy the motor.

Thanks for the response. I am running a single tank conversion, with a pre-heater just before the injector pump. I was just concerned about the pH of peanut oil.

Nay on single tank conversions. Actually nay on WVO/SVO in general and single tank in particular. Cook that stuff into biodiesel and THEN put it in your car.

There have been numerous threads as to the pros and cons of WVO/SVO vs biodiesel and I'd rather not repeat them now. It's getting near bed time for me.

A pre-heater before the injection pump sounds a lot like a LOVECRAFT system. Is that what you are running? If so, your engine will soon die. In fact, on a single tank system, it will probably die either way....that is not the right way to run veg oil at all, it will be no where near hot enough. The IP circulates a few gallons of fuel a minute while driving....no way is that oil 160+F when it is injected to the engine.

You're slowly killing your car.

Just some anecdotal data to further the thread. I have an 87 300D Turbo which began running a blend at 293K. It currently has 344K and shows no performance degradation. I also have a 98 E300 Which had a Greasecar two tank system and FPHE installed at 148K. It now has 200K and also runs like new. Had I burned d2 for that 50K I would have spent @$4400 on fuel. I am sure I have spent less than $400 on supplies in the last two years. So I have saved around $4000. I also enjoy the green aspect but most of all I can tell shiek abdul to take his barell of oil and shove it.

To answer the OP, peanut oil will work great but you really do need more heat. At least add a heat exchanger.

You will get both answers in this forum. Ranging from "no problems, go ahead" to "your car WILL die if you do it".

Personally, I've only seen anecdotal evidence regarding the destruction of engines using properly filtered WVO. I've run a few hundred gallons with no mechanical problems attributed to using the WVO. I've had clogged filters and one tank screen, but I can't directly point the clogged screen specifically at WVO.

That was with a compressed air fuel injection systen back close to around the year 1900.
With the compressed air injection system there is no Elements/plungers and barrels in the system to wear out.
Also labor to repair engines back then was way cheaper than now.

yup, go get one of those stationary single piston air injected peanut oil powered motors and try and drive your car...
The diesel engine was designed to run on available peanut oil for the farmer to have fuel to do work on the farm...
THIS diesel engine was designed to operate on the petroleum fuel sold in fuel stations, and the pump and injectors were designed to burn it.

other fuels will run in this motor, but they need additional additives, maintenance, filtering, etc to work properly in THIS motor.

I've had clogged filters and one tank screen, but I can't directly point the clogged screen specifically at WVO.

Opinion on Filters:
Before I was a memeber of this Forum I was a person who just changed filters with whatever was made for that vehicle without ever really understanding them.

The rateings you see are mostly Nominal Ratings. A Nominal Rating means that whatever the number; lets say 10 microns that the filter will filter out only 50% of the 10 micron and larger particles during one pass through the filter media.

How, much larger than 10microns? From what I have read in the 20-30 micron range.

So how is it possible for your Fuel System to survive this?
What I believe is your fuel system survives because the same fuel is passed through the filter 100s of times while you are driving.
With the above and clean fuel to begin with the actual amount of particles that need to be filtered out is small and your fuel ends up pretty clean.
When you overload your filter with something like WVO or badly contaminated D2 you must be haveing a huge amount of large particles passing thorugh the filter.

You have a Clean Fuel (D2) verses a Dirty Fuel WVO with a large volume of large particles passing thorug the Nominal Rated Filter Elements (your Seconday/Spin-on Filter is a 10 nominal Micron filter).
The filtration solution is to ad on a large Primary Filter to replace Plastic Primary one in the order of 10 nominal microns and a larger Seconday Filter of 5 nominal microns or less.

Notice none of the above has anything to do with heating the fuel; which is a separate issue.

I filter down to 5 microns before it even goes into the car. Of course, filtering will have nothing to do with the pH. Guess I need to get a tester and see how bad this stuff actually is.

peanut oil is one of the better oils to use.

but as you see there are a lot of opinions about your system...and opinions are like....well

any WVO system is "experimental" so use your best judgment as to how to go about using WVO....but peanut oil is a good oil to use.

I actually have a question about this. I've ALWAYS wanted to run some sort of vegetable oil in my tank just to try it out. There is no place that offers BioDiesel anywhere near me.

I read on all types of these threads about needing to preheat oil or oil can't be cool and things such as that. But I live in the desert, and today it's going to be a hellish 117 high, plus the heat from the motor. Isn't that enough? Couldn't I just put a gallon or two of SVO in my tank without any worries?

Would it be THAT horrible if the tank was almost empty and I put about two gallons of SVO in the tank and run it?
