Maybe someone else has thought of this and can throw in their two cents. I'm thinking about starting to use some vegetable oil to decrease the amount of diesel I buy a week. But I have a couple of questions. I don't really want to put a tank in the bed b/c of my toolbox and gooseneck hitch. What would be a safe percentage of vegetable oil vs. diesel? I live in mississippi and gelling won't be a problem again till november or december. I'd like to just add both to the tank and burn them together if they'll mix. My second question is, do you think that it would affect the injector warranty, or special policy (whichever you prefer). Any and all input will be appreciated.

I've always heard 20% but thats just my .02

Its not really the gelling you need to worry about. Its actually the temp of the oil. To get a complete burn and not gunk up the injectors, the oil need to be a BARE MINIMUM of 100F, preferred 160+ F.

I run Veggie in my Jetta, and while it will run on the oil before it gets to my preferred temp, I try to avoid it so i dont have to pull and clean my injectors after a few K miles.

Also make sure to filter it down ( i go down to 2 micron) enough to no clog up your filters. Water separation is key as well.

I need to do a good write up for it seeing as i am going to convert my 6.5TD to run the 'erl as well

Thanks poopface. But if I'm only running a percentage of wvo, and not straight, do you think the temp issue is still a concern?

i havent tried to mix the two, but its probably worth testing in a bucket just to see if they actually mix. If there is a huge difference in the weight of the two, one would just sink to the bottom and they would still be separate.

I think if they were to mix together well, the temp issue wouldnt be as much of a concern since the engine temp will raise the fuel temp when it passes over/ gets to the IP.
