Hi Zxcv
Biodiesel is probably a good idea in its own right but the main reason why farmers / ranchers / heavy equipment operators drive personal diesel powered vehicles is because they have access to off road diesel fuel. ‘Off road’ means little or no tax.
The problem with off road diesel is that it has a pink or purple dye in it. I have never heard of anyone getting caught using off road diesel in a personal rig but the penalties are reported to be severe.
A product that might sell very well would be a chemical additive that would deactivate the colored dye. You could mix it in with the bio-diesel.
No this is not quite right. The reason farmer/ranchers use deicil is two fold.
1. It is historically cheaper than gasoline. Sure they can get the offroad taxless stuff, but they can only use than in heavy equipment (its tens of thousands of dolars in fines if you get caught with died diesel in a road vehicle, and they do check).
2. Since they use it in heavy machinery, they often use it in road vehicles. This is because they have it around, plus they need the power that a big diesel pickup has. Diesel also gets better mpg.
If bio-diesel was available farmers, ranchers, and contracters would use it in a heartbeat. Better to support local farmers than foreign bomb carrying arabs.
