04 Interstate Veggie Oil Conversion

[Free Pony]

Hey has anyone here run their rig on veggie oil? I’ve run my 1980’s Mercedes W123 engines on it and my ‘82 VW Vanagon (with Jetta engine) and I was doing a mix of diesel and veg - 20/80 in summer and 80/20 in winter. I’d BJ love to hear your experiences!

From my understanding, the newer diesels do not respond that well with veggie oil.
Older ones did pretty darn well I hear- but I have heard more poor results with newer ones.

For newer ones I'm pretty sure there are all kinds of warnings against biodiesel above 20%, and even 20% is something that should only be used in an emergency. Maximum approved biodiesel content for regular use is no more than 5%.

Here's a link to what appears to be an official Mercedes brochure on the topic, although it's not on an official Mercedes site: http://www.sprinter-rv.com/wp-conten...iesel_rev5.pdf
