Did anyone try to converting NGas, it seems very efficient. Approximately 50mils for 2gge tank and it cost about 50cents. When I went to Brazil this year I saw most of cars are running NGas. Basically u use NGas first and when it runs out it will automatically change to regular gas.

What do you think guys!!!

I never understood why the US wouldn't encourage it. Globally it's very common and CHEAP!!

I'm with u, it also can be so clean air
