What kind of return on investment (ROI) can i expect?
Return on Investment. How long will it take to pay for the system? This number depends on a few factors such as how much driving you do, your vehicles average mpg, the cost of diesel, and cost of your alternative fuel. But the basic formula is – (miles driven monthly)/mpg to equal fuel consumed. Then multiply “fuel consumed” by cost of diesel. This gives you your cost of diesel per month. Divide cost of Alternative fuel setup by monthly diesel cost and that will give you your approximate ROI. Be sure to include any hidden costs such as filtering system, collection costs, installation, etc. Ex- 3,000miles per month divided by 15mpg=200gallons. 200gallons times 4.25 local diesel cost =$850/month. $5,000(system TOTAL cost) divided by 850=5.8 or just about 6 months.
