Difference between Domestic LPG and Auto LPG

can we use domestic lpg instead of auto lpg?

Thanks vidhur

Your information is quite useful. I have a further query. what is the difference between wagonr's duo and CNG model. I actually want to purchase a car with CNG and LPG both.  

Beside it If you can suggest me a second hand car which can be used with CNG/LPG both. I have a low budget of Rs 2 L and I want the running cost to be minimum as I have to travel a lot in and outside delhi. Or u suggest me to take a diesel car.

wagonr duo is the one with lpg and wagonr cng is the one with cng...there is no such car that can run on both lpg and cng...

you have pretty decent budget for used car...

whats your daily running that would be helpfull in suggesting you a diesel or cng/lpg..??...
