Not from such a poorly-defined starting point, no.

I'm calling Rule #75 on this one..

I would say the saving in the cost of LPG by the use of CNG would be around 100% of the cost of LPG.

Are you questioning the financial viability of a full conversion to LPG from diesel, or for a supplemental conversion to operate LPG over Diesel. Are you wanting to use a full CNG conversion on a diesel motor or a supplemental CNG system?

Is this conversion going to be for a Vehicle, Boat, Generator, Irrigation Pump?

Is this a new motor or and old motor.

If it is an old motor will it be rebuilt to spec prior to the conversion?

There are lots more questions that need to be satisfied before you can acheive a reasonable answer.

Please refer to these previous threads on this subject.
