Guys, Gals can anyone shed any light if there is any difference in LPG quality from different suppilers like Asda, Morrisons, Shell etc..
For some reason I notice better miles per fill up from Shell than Asda. Where Shell is selling LPG at 47.9 and Asda at 41.9
It most likely to be my driving but on various occasions its done this, i only fill up from Shell occasionally as its open 24 hours and Asda is not and its the closest one to me (2miles) the Asda one is about 9 miles (Still works out cheaper going to Asda)
