hi Daniel, i have no trouble with the high flow i don't use the trigger set like i do filling up a truck, just harder to fill all the way as larger diamiter nozzle. the one i mostly use uses different storage tanks but diesel fuel is same same price too. but not sure about other servos on the hwy never needed to refill on my trips as always less than 1,200. when i do trip to melb i'll take a 20L jerry, refill with that at gf's as it will use around that to her place then will just drive to melb. will prob do same when go to SA. but will use my ChemTech diesel power, does not give you more power though, more an insurance. but i'd say use BP keep all recepts as they say they stand by there fuel. i know a guy that used only Caltex kept all recepts had a motor go south on him needed a compleat rebuild was found fuel was at falt, Caltex covered that as he kept all fuel recepts like i do, this was a while back.
