Start at 70/30 WVO/RUG. As the seasons progress toward higher average temperatures decrease RUG to as little as 10%. Add Power Service Diesel Kleen and Biocide.

Put some of your filtered WVO in the refrigerator and or freezer to see what to expect at low temps.

I carry a couple gallons of diesel in a jug in my trunk. I will run the car out of diesel and add a gallon to get me home. Then fill-up with blend.

When running experimental fuels always carry spare filters and tools to change them.

I added an electric pump back at the tank outlet. I recommend this for anyone experimenting with fuels.

If you haven't cleaned the screen in your tank it would be a good idea to clean it before you start experiments. Ask for the Orings at the MB dealer. One for the screen and one for the sending unit.
