Re: how many of u on gas?
Neither , both are a pain in the ass and not worth the hassle.
Duel fuel, car will never run right on one of the two. Straight gas, only my opinion, but id never own a car that runs on just gas, not a big fan.
If you doing this to save money on petrol, consider twice because the money that you spend in putting in the gas system, you most likely wont save that in fuel costs. To save money by doing this, you would need to be doing alot of k's and keep you car for another 5 years or more.
Just something to consider.
