I have a dual fuel powered dodge 5,9 it runs on regular fuel and on a mix off propane/butane.
The tank (230 litre) is mounted at back of 6.5" bed.
It`s starts on regular fuel and than it`s switching over about 10 seconds too the propane/butane mix.
The system has his own computer and is using his own fuelinjectors(no change you have a backfire).The gasmilage is the same as where you run regular fuel and defently no powerloss.
The reason ive done it is because the price for a litre fuel.
1 litre regular octane 98 cost 1,29 euro/1,72 dollar
1 litre propane/butane octane 102 cost 0,40 euro/0,53 dollar
so i am saving a lot of money.
