I had a 6.0 that got that good of fuel millage on almost every tank. Only because it broke down on almost every tank and was on a flatbed for at least a hundered miles to get to the dealer I bouget it from.
Could it potentially be worth it if you ran the propane and actually saw an increase like this in mileage or at least similar to this. If so, what kind of propane system would you need and what affects on the motor would the propane cause? What about compressed natural gas as an option, that might be cheaper than propane? Hell if its possible, I have a decent sized stainless tank we took off of a truck at work I might be able to use?
Around here diesel goes about $4.09/gal ($29.21/MMBTU)
Propane goes about $2.79/gal ($29.36/MMBTU)
CNG goes for around $1.50/gge ($12.50/MMBTU)
That's retail at a filling station set up for fueling motor vehicles.
CNG has an advantage because its not taxed. That will certainly change, at least in commercial filling stations.
Propane and CNG are just auxiliary fuel. By themselves they'd never run a diesel as their cetane rating is too low. In a diesel you used the No.2 injector as a spark plug to blowtorch the aux fuel into burning.
The guy is not being honest with us (or himself) because he is not telling us the propane flow rate.
CNG requires tanks and piping rated for either 3,000 or 3,600 psig. Don't know about propane. To make CNG you need a compressor that looks a lot like a scuba air compressor but with a bigger aftercooler.
There is (or was) a home CNG compressor called a PHYLL that would take a day or two to fill a 10 gallon equivalent CNG tank. It needed 240 V power and a regular residential gas service. A big (more commercial style) Ingersoll-Rand compressor needs a 480V 3 phase service and 50 psi gas service. It will fill up a 10 gallon equivalent tank in about 12 hours.
If I had an economical source of either gaseous fuel I'd use it in a spark-ignition engine. It would be simpler.
He should be in the area of about 20% LP, much more and it will cause trouble. so take 40mpg x 20% and thats about 32. take 32 x 20% and thats about 26. But its hard to stay at 20% without computer controls. There is a system out there, I install them but Im not going to advertise on here. We see roughly 20-30% increase in mpg with it to give you an idea.
I have a 2004 6.0 CCSB with a 4” lift on 315/75r16s and hand calculated I am looking at 13-13.5 all year long. No matter if it’s highway or city, summer or winter fuel. The truck is bulletproofed and has just about every popular 6.0 mod. Straight pipe exhaust and all that. Is this what everyone...
I've had this truck for close over two years now and have done a lot of work to it, new exhaust from turbo back (3"), Tymar intake with high flow Donaldson element, new tires, stock burn TS performance chip and a bunch of other stuff that probably never affects mileage. I log my fillups every...
I have been doing a small test concerning fuel efficiency. I have only recently began using a fuel additive (Diesel Kleen) within the last 1000 to 1500 miles. I plan on switching to Opti-Lube Summer and XL
1st photo is while driving at 70 mph on flat ground holding 23 mpg. This has not been...
Greetings, my name is Thaddeus and I am pleased to meet you all.
In short I will be purchasing a 99-02 F250 crew cab 7.3L in the near future as my brother has a 99 and I love it.
So I joined this forum to ask you pro's for recommendations for the best possible fuel economy.
I am a calm...
