GinJer, our narrowboat, is only a few weeks old, including the engine. We've only filled once with diesel and so the time is approaching to fill up again. A few questions, I've tried to look at previous answers but cant find any definate answers.
Do we need to routinely use diesel additives or do we use none unless there is a problem, how would we know we have a problem with the diesel?
Ive heard we need to sign a disclaimer on the percentage used for heating / cruising charged at diffrent rates, how do we decide?
Do you recommend buying diesel from marinas or from the passing traders on boats?
