Laying up your Austin 7 for a few months.

 

Petrol.

Modern petrol has ethanol which will become less volatile more quickly than older petrol and will erode old fuel systems. We recommend draining the whole system. Alternatively add Ethanolmate if you do not already have it in the petrol and make sure it reaches the carburettor.

 

Water.

If you have antifreeze of a reasonable strength it will protect the water system and can be left in the system. Otherwise drain all the water out and leave the filler cap on the bonnet or on the driverís seat to remind you not to start the engine until you have replaced the water.

 

Oil

Oil will deteriorate over time but not just for a few months.  If laying-up for longer and if it has oil that has done some considerable miles, drain and put fresh oil in.

 

Engine

Even if there is petrol still in the tank, it is not advisable to keep starting the engine for a few minutes in, say, the garage as it will not get to a high temperature just turning without a load and will encourage condensation.  Instead turn it over on the starting handle or on the starter motor before recharging the battery every month.

 

Tyres

Tyres will develop a flat spot if they are left standing in the same place for long. So either jack the whole car up and put it on axle stands or over inflate the tyres to 35-40 p.s.i.

New cars coming off the production line, usually have the tyres over-inflated so they do not flat-spot while waiting for delivery.

 

Battery

Batteries will naturally discharge slowly even when disconnected. Disconnect the battery and keep it fully charged either by the use of a battery charger that has the facility to automatically keep the battery fully charged or make a note in your diary to put the battery on charge every month. Do not discharge and recharge it, as advised in some publications, this will only harm a car battery. They are not designed to be fully discharged, known as deep cycling, as in caravan batteries.
