Oh I was such a nerd about it. At first I just put 4 gallons in about 14 of diesel. Then more, more, more. I figure I ended up burning about 75% veg to 25%. Every time I would add more I would get MedMech to post it on the diesel forum (we had no power or internet, ect....) and I would funnel it right in! It ran perfectly (98 e300 Turbodiesel). I don't have the time to mess with WVO, which is a shame because I have an unlimited free source.

When it gets warm again, I may order a 55gal drum of SVO to get my fix I can get it for around $2.10 delivered and I have a pump for my tractors.
