My 3b runs smoother and may "tach" a LIL faster on bio diesel.
It most likely only feels faster since the engine is running that much smoother.
The smell from the exhaust is appealing to me to for many reasons.
1st, it smells like COL Sanders is cooking. MMM
2nd, the bio exhaust doesn't stink up pedestrian laden service and delivery parking zones. (ie in front of hospitals/starbucks etc.)
This allows me to leave the bj running on short trips w/o choking anyone. (key removed, steering wheel locked, bulldog on front seat)
Making bio is a fairly simple chemical process.
Here are the BASICS:
Test used oil for fat concentration. This determines the amount of lye required.
Heat 40 gallons of waste oil to 120* in an old hot water heater.
Add lye and 10 gallons of methanol to the heated oil.
This will remove the glycerin from the mix.
(Glycerin makes used veggie oil thicken at room temperature)
Add h20 to the mix. Stir. Let mix sit overnight.
Remove h20. (repeat this step if desired)
The h20 will help remove any remaining particle matter.
Your now have Bio Diesel.
