cng gas aka ngv is methane gas.

its lighter than air itself. if it leaks or explode it will not create a big fireball. it will disperse into air very quick since its lighter.

ngv gas is rated 110 RON. so knocking will happen in the engine.
It runs very lean and actualy quite damaging to the tepet and valve seal .

Need to run petrol time to time to lubricate the engine.

some stupid ppl go put cooknig gas tank which cant even hold more than 1k psi.

Ngv tank are rated till 4500psi and DOT tested and stamp to show its lifespan and expiry rate before its ship out for use.

sometimes u need the right info not just listening from pipu saying explode and dangerous.

but if ur a heavy user then it justifiable to use NGV. Else stick to petrol.

yeah what about it?
