blending WVO and petro diesel

I wanted to see if anyone knows what the maximum percentatge of WVO that can be blended with petro diesel without modifying the fuel system. I know this is temp dependant too.

Thanks,

burnan

I blended last year in Michigan and didn't have any problems. Of course, that doesn't mean anything. The risks are there. I averaged 4 gallons of really well filtered wvo per fill up. When it was really hot (90's), I tried a 50/50 blend only when I knew I was going to burn the whole tank , i.e. on a road trip. Currently I'm looking into a second heated tank system, and would strongly recommend that if you see yourself burning vegoil long term. By the way, if you need some filtering bags, I've got an extra 5 micron and 1 micron bag that I'd sell for $10.00 for the set (plus shipping). Take care, happy motoring.

FWIW, I've run straight WVO and virgin oil down to 45F. I expereinced significantly reduced power and a reluctance to idle at the right speed until operating temps were up. Once the engine was hot, everything was OK.

Diesels dirt cheap; cheaper than milk, cheaper than cooking oils, cheaper than bottled water! But wait, after subsidies, is it cheap?

I've taken to buying tubs of soy oil at Smart & Final and mixing it with diesel fuel (20-30% SVO in my tank) because it's actually cheaper than diesel fuel ($2.80/gallon, ouch). Car runs smoother, no apparent decrease in milage either .

Yep, the weather is warm and I'm running straight WVO now. Depending on where you look, diesel in Waterloo is anywhere from 2.09 to 2.38.

I have better luck blending WVO with gasoline. I presently mix about 70/30 WVO/RUG. I have run nearly straight veg oil in warm weather. The only modification to my car is an electric pump back at the fuel tank outlet.

I have read the blend nightmare thread and have read parts of it several times. But you have to take into consideration that WVO is not a product standard. Anything that some minimum wage restaurant clean-up person dumps into a jug or a dumpster is WVO. There is no telling what that poor guy dumped into his fuel tank. I have a limited supply of high quality oil and have had no problems remotely like anything mentioned in that thread.

I think the thread is mostly BS and contained no information that changed anything about the way I burn or view Veg oil.

If you are not up to experimental work in diesel fuel systems you will likely have problems with WVO in your Mercedes, that is about the size of it. There are many people out there who are willing to take your money for systems, parts and knowledge to help you run veg oil in your car. But when your car quits running on the side of the road somewhere you are on your own.

There are many people out there who think they are going to make a lot of money from veg oil or biodiesel and the politics and misinformation are apparent if you read much about the subjects.
