yes, but for how long? and what kind of maintenance issues are you likely to encounter?

if the veggie is well filtered it will certainly burn in the engine, however you will likely have all sorts of problems with all the rubber parts, hoses, orings, pump seals, lift pump diaphram (maybe) to deal with.

then there will be an issue with piston rings getting gummed up

and then unburned or partially burned veggie getting into the lube oil, polymerizing into a goop that is hard on lower end components

so, if you change out some rubber parts, which likely need changing anyway due to age, and  if you change oil a bit more frequently, and set it up to start and shutdown on dino diesel, and maybe switch to and fro during the drive just to keep things as clean as possible, you can probably get by using it.

you probably will have to heat the veggie for it to flow and make it through the system in cooler weather and definitely in cold weather.

short answer, is yes it can be done, the reality is a bit more detailed to do it right.

I'm running my Isuzu NPR on about 30% WVO blended with 15% RUG, few ounces of cetene and topped off with a splash of Acetone.  I haven't been doing this long and when the truck is going to not be started for a month or more I fill it up with B20.  Oh, this WVO concoction is blended with B20.  And the truck lives in Hawaii where 85 is really really warm and 67 degrees is my personal witness low. 

I can't see any difference in performance but it's only been a thousand miles or so - hardly getting started.

You might find a lot more activity on these forums:

http://biodiesel.infopop.cc/groupee/forums (http://biodiesel.infopop.cc/groupee/forums)

Both biodiesel and SVO (straight vegetable oil) discussion forums there have quite a bit of information.

Thanks for the imput, I've been running a FieldMarshall 6/1 on wvo for 3-4 years not, turning an ST5 generator to power my house, few problems here and there, just got it back running after quite some time off, anyway I have a large stock-pile of WVO, which is why I'm thinking of a vehicle powered that way. I really don't want to make bio-diesel, just don't have the time to do it........and want another choice besides gas. Mike

You might gain some insights by taking a look at the work and development done by Dan MacAmoil with his raw fuel.

I have over 40,000 miles on WVO in a '95 Suburban (total miles are 224,000)
This weekend, I just picked up a '94 F250 TD to veg.  Your truck will run well for many miles on a heated two tank system.
Rubber parts are eaten up MUCH faster with biodiesel than WVO.

I looked at his site. All the info seemed to be around 4-5 years old. I wonder what the latest is on this fuel.

I will ask Dan about his website updates... I know he is still running his farm on raw sunflower oil that he grows and presses himself. He also has quite a few successful years of operation under his belt and he powers his seed press with Lister clone engines as well.

ok, next dumb question, how do I heat the tank on this truck? or can I simply mix the WVO with RUG? thanks Mike

Hello Mikern,
                    The simple answer is to go to the Biodiesel link that Thob posted above, and do LOTS of reading. Look at the SVO threads and the specific vehicle headings. Yours is probably there. A successful heated system is no 5 minute job, so read all you can, do some Google searches and ask lots of questions, and with patience you can succeed. A very good oil settling and filtering system is essential. Only start the project if you have spare time and patience. With a lot of homework you will get there . Good luck,  Combustor.

Hey mikern,

I get away with what I do because I'm in the tropics.  Where are you makes A big difference in how much help your engine / pump / injectors need to process the VO.  So where are you?  How do the temperatures run where you want to run?

When it gets down to 67 degrees (personal record for me here in South Kona) I feel justified putting on socks first thing in the morning.  Brrrrrrrrrrrrrrr

But it should be warm enough for blending during those months without a "R" in them and maybe until the end of September.

I completely agree with this, as this is my experience with my '91 Dodge.  WVO doesn't hurt rubber - it's BioD that does.   Just make sure to clean - filter- your oil.

I have seen a lot of people search for the holy grail of fuel line that will stand up to Bio. See them pay a LOT of money for that fuel line only to be dissapointed.

I use the cheapest stuff I can get and NEVER had a problem.
The braided clear line I use is Cheap as chips and hardens with oil and goes soft with bio..... But it takes a while to do it.
In the meantime I have an annual maintence thing I do between Christmas and new year. Changing the soft line is part of that schedule.  There is probably only half a meter of the stuff on my vehicle in 3-4 pieces so it's not a big deal or time consuming to change.

Stuff lasts 14-18 months so I know if I change it every 12 months, I'll never have a problem and never Have.

I had good luck with urethane tubing for B99 for a few years.  Not terribly expensive. No hardening or softening, just turns amber color slowly over the years.
