I get around 22-24 mpg in my 300D on regular diesel
The other day I mixed 10 gal WVO + 3.077 gal of Diesel =
97.8 MPGe
(this is the mpg I actually pay for at the pump)
single tank system:
(weather never falls below 65F)
30 plate heat exchanger
inline fuel pump
glow plug heater (on a manual switch)
free waste veggie oil filtered to 1 micron
im glad i finally made this a reality
car is running good. i can go 60mph uphill which is a big plus for me
