Does petrol really go stale?

Petrol from the pump is a mix of many components (over 100) with different properties that determine the performance of the fuel. If left in an open container it will in time evaporate completely, but as it evaporates the make up of the fuel will change as different chemical components evaporate at different rates. This evaporation also happens in fuel cans and tanks and the process of degradation starts the moment the fuel is purchased.

Petrol will generally last for around 3 weeks at summer temperature in a vented fuel tank, after which time the performance will suffer, and it will be best to add fresh fuel to restore the performance. Petrol in a sealed container will last for more than 6 months before the performance suffers too much.

Fuel stored in underground garage tanks is unlikely to degrade much because of the rate of replenishment, except in remote, small garages which these days are rarely found.

How the petrol changes in the vehicles fuel tank.

The lighter components evaporate first, these are the chemicals that provide valuable octane benefits on starting from cold. These are very volatile and compose most of the fuel/air mix during initial start up, but when they are depleted by evaporation the mixture becomes lean, causing higher temperatures, detonation, pre-ignition and piston damage.

The fuel that remains when the volatile parts have gone has a higher density, as well as a higher octane, but as it is not as volatile, cold starting is impaired. Because fuel is metred by volume the mixture now becomes rich because of the extra amount of fuel in the denser liquid. This richness will cause plug fouling and blocked exhaust ports due to carbon deposits, but the lack of volatile octane will suppress full revs.

So, in short, marginal fuel will result in hard starting and lack of top end revs and power, but the vehicle will run once started.

Formation of Gums and Peroxides.

After several months storage at summer temperature the petrol will start to form peroxides and gums. The degradation will continue as the fuel ages and the peroxides which form will slowly attack the soft materials in the fuel system. The first to suffer will be the rubber and plastic fuel hoses, which will fall apart, followed by the fuel pump. Eventually even the harder plastic and metal parts of the fuel tank will be eroded as well as the fuel lines and injectors.

The 'gums' or 'varnish' are solid material which forms and lines the inside of the fuel tank, blocking the microscopic bores and jets, thereby effecting the functioning of the fuel injectors.

Stale fuel is the number one cause of stiff metering diaphragms and the primary cause of fuel pump replacement. Gums and varnish will quickly stick the piston rings of a running engine causing expensive failure.

If this engine is lucky enough to start it will run on ethanol with no added oil and rapid engine damage will occur, but more commonly the damage is done during storage while the phase separated fuel corrodes away the inside of the fuel system, causing expensive repair which is not covered by warranty.

Stale petrol is nothing new.

We had the problem of stale fuel long before the addition of Ethanol, its just that todays fuel turns bad much quicker than in the past, in fact, depending on temperature, light and humidity, the fuel can be unusable in as little as 30 days. The ethanol speeds up the process for two reasons, the affinity to water mentioned above, and the fact that ethanol is oxygen rich which speeds up the oxidation process which turns petrol stale.

How do we overcome the problem?

1. Keep you fuel fresh buy using it and topping up regally.

2.Purchase only enough fuel for 30 days use.

3.Use a fuel additive such as stable. If this is added correctly to fresh petrol at the time of purchase then your fuel should stay usable for up to 6 months. Remember that additives will never be able to rejuvenate old, stale petrol whatever they claim on the bottle.

4. You could try draining your fuel tank before storage, some manufacturers even recommend this.

How to recognise stale petrol.

As petrol ages it will change noticeably in colour, smell, and viscosity. New petrol, fresh from the garage, will have a pleasant 'tang' and will be almost clear, with just a slight colour, but as it ages it will develop an unpleasant smell more akin paint or varnish which will linger on materials or skin for a good while, whilst the colour will deepen considerably. The old fuel will also become much thicker, more akin to very light oil or diesel fuel. Really old petrol will have a very heavy and unpleasant smell and can be very dark in colour, whilst being very thick, more like a liquor.

What is the best solution?

The best solution by far is to keep the fuel fresh and if it has gone off it all needs to be thoroughly cleaned. In addition, the clean burning nature of the fuel will ensure that the internal workings of the engine stay clear of any gums, varnish, or carbon residues.
