I'm gonna throw this out there for discussion.
Just got some info as follows
They suggest 25% propane(liquid) to 75% diesel ratio.
We have a 250 gal. diesel tank so in order to get an equivalent capacity of propane so as to run both fuel sources empty from full simultaneously, at a 25% rate we would need 65 gal. of propane. It is 4.64 pounds to the gal. for propane so it would take a 300lb tank to hold 65 gal., to cover a full load of diesel. Since we never run till empty a 150 or 200 lb tank would be sufficient. Don't know how big that is, but I'm gonna look into it.
This fella told me a gentleman in Wis. with a 12 liter. Cat went from 6.5 to 12.9 with a 25 to 75% mixture. Also a OTR trucker customer estimated he saved 14000 bucks last year in fuel costs. They also boast of 20% gains or better in HP while simultaneously lowering engine temps. by 5 to 10%.
The tank could be mounted in our P/U, our toad, in the front of the bed under the cap if too large for a bay?
Thinking out loud. Currently 250 gal fuel tank at 5mpg gets us 1250 miles. If we add an additional 65 gal of propane for a new combined fuel capacity of 315 gal it could potentially get us 3000+ miles and the propane is also less per gal., currently 2 bucks.
At 2.77 a gal. it is currently 700 bucks for 250 gal. of diesel +130 for the 65 gal. of propane=830 bucks to go say 3000 miles= 28 cents a mile for fuel.
Currently it would take 600 gal. of diesel at 5 MPG and at 2.77 a gal that comes out to 1662 dollars or 55 cents a mile. If their predictions on the increases in mileage are correct that would be a 50% decrease in fuel costs per mile.
Is this worth looking into?
He told me they were interested in setting up a DD 2-stroke, I suggested our bus as a test platform, he was receptive.
What say you?
