• The number of miles that your car will be traveling every year, this accompanied with your car propane kits usage will determine how much money saved.
• The original fuel economy of the vehicle, what if you switch and the fuel economy is actually not even as good as it was before
• The initial cost to convert from regular to car propane kits
• Lastly, the vehicle resale value after you convert this car, this being if you plan on ever selling your vehicle

During and after the conversion there are many things to think bout as well, fuel tank and other components will add weight to the vehicle which will also slightly increase the consumption of fuel used during each mile. Propane costs for the fleet types of vehicles typically range from 5 all the way up to 30 percent less than conventional regular gasoline. In he end many states will offer tax incentives for using cleaner fuels, this will further reduce costs and may be a huge determining factor in whether or not to buy the car propane kits!

There are a slew of engine upgrades that are unnecessary to run on hydrogen alone. An example would be that hydro is very susceptible to the pre ignition of an engine this would mean the car propane kits would not work proper in this situation, during pre ignition special care has to be taken and is considered ultimately necessary because backfire and such can create bombs. Hydro is way tougher on injectors than regular fuels because it is much more drier and leads to way faster wear on the injectors themselves!
