I bought a nice big Ford Super crew F150 over a year ago. It came as a dual fuel vehicle. I can run regular gasoline and I can run propane. When I bought it, I though “that’s cool, but I’ll never use it”. I would have to say that things have changed a little bit.
Gas at the lowest right now (5/15/2007) is about $3.25 a gallon. Propane when I fill up at the local U-Haul store is $2.23 a gallon ($1.91 in Las Vegas). You might thing “man, that’s way less” but there is a difference in performance and gas millage.
When I run Gas, I get about 14 – 15 MPG. That calculates out to about .22 cents a mile. When I run on Propane, I only get about 11 MPG. Propane per mile cost me about .20 cents per mile. (less when I filled up in Las Vegas). There is no difference on the highway or in the city (actually, it’s like that with gas also with this truck).
Propane has a considerable drop in performance also. I feel like I have a squishy gas pedal because there really isn’t a good throttle response. But, I do like to run it for several reasons. Besides the fact that it costs less to run (not by much), I also like to know that it’s a clean burning fuel AND it is runs my vehicle at an unbelievable cool temperatures. The water temp hardly even reaches the cold line on my gauge when I am on Propane. When I switch back to gas, it’s up to the middle of the gauge. Propane does have some strange smell you can pick up some times.
With Gas prices rising, I am sure propane will make a considerable positive dent in my pocket book. As long as they don’t raise the price of propane any time soon, I will be happy.
This month I am going to try and run totally on propane. I have heard that because it’s not a carbon based fuel that your engine oil does not darken with time and miles. I just got the oil changed and I would like to see me put 1 – 3 thousand miles on it and then test it out. I will report back on that soon.
Anyhow, if you have a car that support propane call around and see what the cost per gallon is. I have found good luck with U-Haul centers. Just ask them for their costs on Highway propane.
