propane
With the high cost of fuel has any one had any experiences with propane injection? If you have what kind of system and do you have any increase in mileage? I pull a large 5th wheel and have the power but would really like to break out about the 9-10 range if possible. I know that horsepower needs to be fed and maybe the propane would do it. Thanks.

This may sound like preaching, you can increase your mileage without any added expense. I transport RVs and when I first started I thought it was great to be able to run 70 or 75 out west. What I only found out through experimentation is that I would only get 10 mpg at 65 and as low as 7 mpg at 75.
I did a lot of reasearch and trials and found that on the 7.3l PSD with an automatic (E4OD or 4R100) if I ran based on my Tach instead of Speedo. Set your crusie or foot at 2k rpm and you should find your mpg go up to 12-14 depending on the weather of course. It is about 62 mph.
I have found that I would rather spend 5 minutes an hour driving than spending more money on fuel. Even as a transporter that is about 1 hr per day (loaded) but my savings on a west coast delivery (about 2300 miles) is in the area of $300. Mileage is what makes my money, not time, so I gain alot for the little time I loose.
just a thought.

I have seen some ads in Diesel Power that claim 18 on fuel and 26 with propane, but I keep asking: "Why isn't the trucking industry doing it if it works so good?" I've priced some propane systems and all told they go for about $1500 for the parts. Now that does not include installation or any other mods that might be needed or "strongly suggested" such as head studs. There is a forum lower down for this subject, that might be a good place to check out...
