So Big Matt here is saving a nice chunk of coin here (over $200/month) by using straight vegetable oil collected from restaurants.
Here’s how …
* ~$1.60 in propane per 15 gallons of fule (and an hour of his time to burn off excess water from the oil.)
* ~$11 per month in filter replacements. (He buys 2 $16 filters every few months)
So if Matt is using about 60 gallons of fuel per month – $240 total at $4/gallon diesel- he’s saving ~$228.40 per month or $2,740.80 per year.
***Note that Matt made an initial investment of ~$1000 – to convert his diesel truck to run on veggie oil.
