Just acquired an A33 Cefiro with 40L LPG tank. Did all the fluid changes but I noticed it consumes a lot of LPG. Approx 4km/l. What needs to be checked?
Maybe it's just the large engine (3.0L V6)? You can have the LPG system checked with it's installer. IF the air/fuel setting is on the rich side it could explain your car's gas guzzling ways.
