Full Tanks For Winter?

Post by Jonathan Seamons » Thu Oct 20, 2016 4:53 pm

Bit of advice please Guys.
Carerra with twin Volvo Petrol's.
Boat fuel tank is half full at the moment. Nearest petrol from us on the waterside is a 2 day trip or 35 miles there and 35 miles back.
Some people on the marina are saying that even on petrol engines tanks should be brimmed. I thought it was just the diesels at risk of water in the fuel and “The bug”.
I use an ethanol fuel stabilizer product already on the boat.
Its got a 275 litre tank so its a lot of trips with a Jerry can not to mention a quarter of a mile down a towpath .........
Just wondered your thoughts please ?

Having had petrol degradation issues in cars that have stood still for a few months in the past I would be inclined to keep the tanks as empty as possible so you can fill with fresh petrol when you are ready to use her next year. Depends if you want to use the boat during the winter really.

Usual wisdom is
Petrol - empty ('old' petrol can degrade and block carburettors )
Diesel - full (to expel air and to minimise condensation which can help to minimise occurrence of
diesel bug)
