Unless the engine has been built from the bottom up to specifically run on gas you won't get any where near the mileage you normally get from the same engine without gas.

You are right Axle. There are a lot of things that have to be done to a gas engine in order to get the best out of it but they are rarely if ever done during a normal gas conversion because they would more than double the cost of the conversion. If you did go that far, the engine would no longer be suitable for petrol.
Some of the changes include a higher compression ratio, a different cam grind and major changes to the ingition timing at idle and maximum advance.
If the engine has copper/lead bearings, they will be eaten away. We had some of those eaten bearings on display in the classrooom at Ultimo TAFE in
Sydney when I was doing a gas licence course.
I used three gas cars over an eighteen year period for commuting to work. I did not do anything else to the engines except harder exhaust valve seats in two of them and advancing the ignition by two degrees at idle. They really needed about ten more and some taken off at the top.
They were all down on power and higher in consumption in comparison to petrol but I saved a fortune on running costs because of the price difference. Gas prices were always much higher out of
Sydney and I would have not used gas had I been commuting in country areas.
