I'm running reg gas/WVO mix at about 80% WVO on an 84 300td. Filtered a couple times down to 10 microns, then mix the gas with it. Runs great! Smooths out the diesel vibration, smooth as silk, purrs like a kitten. Power is the same. Ran into a problem tho because the mix cleans out the system of all the diesel gunk built up over the years. Got tired of replacing the filters so I removed the fuel tank and cleaned it. Able to replace the small inline filter in about 7.5 minutes now tho. Love the veggies!
