My diesel mechanic told me about using new peanut oil in my Cummins diesel. The recommended ratio is 1 gallon of peanut oil with 2 gallons of #2 diesel fuel. I have been running with this for some time and have not noticed a loss of power or fuel mileage. Costco sells 5 gallon containers of peanut oil for $9.97. When I fill my tank I put in 10 gallons of peanut oil and 20 gallons of diesel fuel. With fuel running around $3.19 per gallon I'm savings about $12.00 per tank

 

I've done tests and read ingrediants of the Costco brand oils..the Golden Chef Soybean Oil is the purest they sell, and best to run.I run a 50/50 mix, going to go 70/30 soon...i wouldn't run it on a 24 valve or common rail..might not be that good..it doesnt gel over til negative numbers either which is nice!
$11.99 for the soy for a 5 gal container

 

hows the peanut oil smell out of the exhaust? does it stink to high hell? thats what ive heard.

 

The only problem is when I drive in a crowded parking lot and all the fat women start following the truck because it smells like McDonalds. Seriously though, there's no difference in the smell, probably because the oil is new, and because it's a 1/3 mix.

 

You got sumpthin again fat women?

 

I'm kinda interested in the use of peanut oil as a fuel. I have a sams club and a costco card so i can get it in bulk too. I'm just curious if you have any starting problems ever or if it runs differently than if you were using just straight #2? From what I gather there aren't really any adverse effects to running peanut oil. Oh and my last question, about how many miles have you been running peanut oil and diesel mix in your truck?

For a short time I ran a mix of new peanut oil + 20% gasoline + cetane booster. No problems whatsoever. Smelled like french fries and blew whiter smoke.

Caryy an extra fuel filter because cooking oil will actually clean the *poop* out of your tank and lines (and motor) and clog up the filter at first.

 

There warm in the winter & shaddy in the summer.

Put in some biodiesel sunday [ about 12 gals of dino in tank , add 2-3 gals bio ]
by wensday the filter plugged , wouldn't start , drained & took off , there was dark color & small particals in the drained fuel & dark color in the inside of the filter .
This makes about 20% , and there is almost no diesel smell , it seems that it takes a little longer to see normal temp on gauge [ fewer BTUs ]
Quiter & smother running .

 

John Faughn hit the nail on the head. Warm and shady.

My truck is still being broken in, there's only 9500 miles on it. About 500 miles using peanut oil. No clogging, no smell, no problems.

 

2 bucks a gallon is better than $3.29. The sticker on the back of my truck says Biodiesel - This Truck Is A Vegetarian I guess it's still a veggy if it's running on peanut oil... I think you guys are onto something here!!

 

I think the rule is, any food which grows underground is a vegitable. Anything that grows above ground is a fruit.

Peanuts are veg. Tomatoes are fruits. SO don't try to run your truck on tomato juice.

Corn grows above ground and it's a vegetable.

 

I'm noticing a lot of mention of peanut oil , are you guys just using that as a genaric term ?
A vast majority of comercialy produced bio-diesel is from soybeens , for a number of resonds , cost , theres a glut of soy-oil , becouse of the lack of use for it [till now ] as a byproduct of making protein meal .
I am going after the used oil , so am not looking at buying new , but I think that if you were using bio , and buying peanut oil , you could save $$$ .

 

I seem to remember reading some where long ago that Mr. Diesel, the man that designed and built the diesel engine, made this engine specifically to run on peanut oil. I could be wrong but that has always stuck in my mind.

 

why not in a 24 valve or common rail ??
