Audi A2 1.4 petrol/LPG Gas

Bought this kind of petrol a2 to see how low the consumption can be with these. It already has a gas conversion kit installed.

On first test noticed that its very handy to have two fuel systems while testing. If you are trying to do avg speed test and there comes cars or road constructions or jams. You can just take notes on km readings and switch to other fuel source. When you are able to bumb the speed up where wanted just switch back to first source. You can even take out the acceleration parts of the equations.

Did my first test I drove total of 87,7 km which I used petrol 68,4km distance and the gas system 19,3km. Fillup was 4,08 liters, which is very little and there migth be of course some error in it. Test speed was set to 120 km/h--->
5,9l/100km @120 km/h. Not bad for the car with current 17" s line wheels. Which will be switched tomorrow for a1 winter wheels 185/60R15 with hubcaps.

Car already has KW lowering spring kit.

Which of you have experience in the gas systems how accurate the filling would be with gas system if you only drive so little as with now on the petrol like 68 km?

It has be my experiences reliable gas refills quantities are hard to accomplish.

On the bright side you may be able to weigh it accurately.

I guess it's nearly the same engine which used to be fitted in the Brazilian VW Kombi from 2006 to 2013.
