The chandlery shop is run by a guy called kieth who happens to be a boater he moors close by my boat in the marina and he is out on his boat Misty Dawn at every opportunity,and he knows his stuff on boat equipment,the best thing about buying gas oil from Sawley is it is FRESH no water from condensation as the tanks are under ground and they sell huge ammounts per day,this is important for boaters who have diesel fired c/heating systems with very fine jets.You may pay a little more per litre but it is the best for your boat.Try stopping at Sawley one day and have a walk around it has everything you could want,so the morale of this story is dont knock it till youve tried it!
