80-100mpge with Mercedes 300D Veggie/WVO Single Tank

[alohaspirit]

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

Good way to go in your climate. Mine, B100 3 seasons, blend down to avoid gelling in winter.

just a few notes:

i installed everything myself

currently running on about 80% waste veggie oil

filtered oil is a must

clean filters are a must

if your car is bogging, one of your filters is probably clogged

a lot of the problems i had in the beginning was from a dirty gas tank
(its best to remove the tank strainer and clean it out as best as possible)
im still getting small things in my filter so i couldve done a better job

I use to have a 240d , however it was difficult to start as is on the #2 stuff. Ive sen those kits,but imagined by time it paid for itself I would need to go ten thousand miles or so.

Whats the break even and pay back point on your system?

Right now Diesel is $4.50-5.50 in Hawaii

Ok, I'm a little confused
I thought to run waste veggie oil, that you had to refine it into biodiesel?

I had no idea you could simply take WVO and filter it and run it in your tank?

Is this the same as running new veggie oil in a separate tank (like the old greasel kits), where you dont turn on the veggie tank till the engine is warm, and then shut if off before you stop to avoid gelling in the engine?

Or do you run this WVO just like biodiesel?
