Portugal guy with Alfa Romeo

Hello, my name is Gil, i'm from Portugal and i've known this forum for a few years but i never registered until now
I have a Alfa Romeo 156 2003 1.6 twin spark with LPG. I have always been interested in efficiency in general, and this forum always popped up when i was doing my aerodynamics and driving research

I'm looking forward to see more of your threads and to learn more about fuel and aerodynamic efficiency

Hello Daox and thank you
LPG it's a bit frustrating because it's really hard to get constant values of L/100km, but the average it's around 9.5 L/100 km(i know it's a bit high...)

I'm not used to LPG as a motor fuel because here in Brazil it's meant to be a stationary and industrial fuel, and CNG is used for road-legal applications instead. But just to compare, what's the usual fuel-efficiency while operating on gasoline?

I never did a complete fuel up on gasoline so i only have the on board computer values for comparison. In a Euro trip i did 6.4 l/100km in 3 weeks and 7500km's in the onboard computer, with the LPG system i got a average (on that same trip) of 9.4 l/100km

The fuel consumption increase with LPG seems to be higher than with ethanol. Well, considering that sometimes Italian ethanol made out of grape leftovers from wineries is imported here in Brazil to keep the regulatory stocks out of the sugarcane season, it does surprise me that grape-based ethanol didn't become popular in Portugal. I know, most of the leftovers are actually turned into some distillates used to "fortify" the wine like it's done with the world-famous Porto wines and the Spanish Xerez...
