Hi i have full time lpg[propane] on my 89 f150 i did notice a difference between the lpg and petrol but it wasnt that big of an issue.
Out here in australia lpg stations are pretty well covered all around the country,but there is still a lot of remote areas,i always plan my trips around the available stations and i get fairly good mileage.
My system went on in 99 and i drove for a few year using dual fuel then finally ditched the petrol side,took out the tanks etc and been on lpg since and not looked back.

 

Not sure whether you are still watching this forum. I have a question about propane truck, need help.

 

Start a new Thread with your question/problems and all the truck info and I / we will try to help

 

Man, old old thread... But to answer the question for future seakers, it was propane only. Started on propane, ran on propane. Worked wonderfully above like 15F - below that, the vaporizer can freeze before the engine generates enough heat.

 

Thanks for the reply, Macrobb!

Recently, many of my friends are switching to gas. Most likely because of the benefits. But here I am also interested in how good it is?
