12.7 mpg on a 170mile run?

So hadn’t ever really worked it out but was with a friend just now and he sat and worked out my mpg on lpg (don’t know why) and I found it very low - I’m not talking what the dash says I’m talking facts. We drove 170 mile 164 of it motorway the rest town and used 61litres of gas which translates to 12.7 mpg... is that normal? Current stable:

No direct experience but given LPG provides substantially lower MPG than petrol this figure does not surprise me at all since with petrol you’d probably only get 15 or 16 MPG?

LPG has a 20% lower calorific value so you will use more for the same power output. So to go from 15 /16 mpg down to 12/13 mpg is about right. 2007 Vogue TDV8 in Zermatt Silver with Charcoal
