My golf 5, built in 2003 has got further after every refueling, since I have installed the Fuelsaver. In average I drove about 540km with a consumption of 7.5 l/100km during the cold season. After the first refueling, it changed to 596km and after the second and the third time 616km and 641km. This is 100km further, 18.5%.
In the warm season, I’m interested to see whether it makes a difference. Summer LPG has a different mixing ratio, and my average consumption was 6.5 l/100km so far. (19/02/2014)
