What's the best way to deal with fuel and the storage of a car over a period of inactivity? Empty the tank or fill it up and use additives to help prevent corrosion?

Overwinter I would suggest a full tank, it leaves the smallest area of metal for condensation to form which is what corrodes the tank, adding a good stabiliser won’t hurt. For longer periods you may want to consider emptying.
However the best way is to drive it when you can, there’s always an odd day where it’s possible..but still keep the tank topped off!Last edited by trunt; 6 February 2023, 03:08.Terry Hunt, Wilmington Delaware

I've just finished a restoration, the first classic car I've had so the first full bare metal resto. Got all the fettling to sort now plus the horror of it getting dirty. What have I done!Comment

You have to also look at the new fuel with the ethanol content, as over a short period of time it will separate. Leaving pure ethanol at the bottom. So when you try to start the car it wont start. Its good idea to stir the tanks regularly. This can be done by just getting the fuel pumps working, providing the system has a fuel return.Comment

It’s called phase separation which takes quite a few months to occur and for it to happen it requires the absorption of water. Keep your tank dry and that’s not going to happen over winter. However, Yes, get non ethanol fuel if you can. I cannot get any and therefore have successfully stored cars with full tanks of E10 for many years now.Originally posted by bullstarz View PostLast edited by trunt; 6 February 2023, 23:26.Terry Hunt, Wilmington Delaware
