I would like to know how the LPG engine and fueling system works. I want to know if the tank in the back trunk is safe and what kind of fuel is used. I’d also like to know if normal gas from a gas station can be used.

Hello, I'm Danny.

LPG fuel system is Liquid Propane Gas. It is the same type used like on an outdoor BBQ. That tank can be filled at most gas stations everywhere. Those tanks are safe as long as not being exposed to spark/flame. No, you cannot use gasoline with an LPG system as they are not compatible. Hope this answers your question and thanks for using 2CarPros.

Thank you very much, your response was very helpful! Two more things though; the LPG tank in the back trunk has to be filled up straight from the tank and not the normal gas tank at the side of the car? Also, can a LPG fueled car be turned into a regular fueled car?

Hello again.

Yes the LPG tank has to be refilled directly on the tank itself. Cars can be converted back to regular gasoline but it requires a different intake and fuel system. The cheapest way to do that would be sourcing the parts from an auto salvage yard. Hope this helps and thanks again for using 2CarPros.

Thank you so much! Is the LPG tank safe? It seems dangerous to practically have a gas tank in the back trunk of your car.

Hello again.

Yes, they are safe. Like I said earlier just as long as not near flame/sparks. Just make sure it's mounted properly to keep from rolling around. Thanks again for using 2CarPros.

I actually did not realize or remember that I already asked that question, my apologies. Thank you very much for your assistance thus far, it has truly brought me clarity on a subject that I knew next to nothing about. The service that you and the numerous staff of 2CarPros provide is excellent and well deserving of a multitude of praise. Again, thank you very much!
