..pay for his valves, I guess he can listen to you.....= )
Oil companies brag about their shelf life, but if you read the fine print you'll see that they recommend 30 to 60 days max. Keep in mind we are talking about modern gaoline, made since 2005, not 3 or more years ago, when the blends were different and did not contain ethanol.

From Chevron:
Boats With In-Board Engines: Follow the general storage recommendations. Seal/close the tank vent if possible.

Boats With Outboard Engines: Follow the recommendations for small-engine equipment (below).

Boat fuel tanks are more likely to be contaminated with water for obvious reasons. Check the fuel tank before storing the boat. Pump out any water and dispose of it in an environmentally responsible way.

Water removal is particularly important for boats used in salt water and for boats fueled with gasoline oxygenated with ethyl alcohol. Salt water corrodes some metals. So does the alcohol-water layer that separates if gasoline containing ethyl alcohol is contaminated with more than one percent water.

Formulation changes that have occurred in the past five years — the addition of oxygenates and the reduction in benzene and other aromatics — have made gasolines more subject to microbial growth. Even if no water is detected, add a biocide to the gasoline in the fuel tank. Follow the label directions. The best mixing is achieved if the biocide is added to the tank before it is filled with gasoline. Biocide additives are available at marinas and boat supply stores.

Small-Engine Equipment

This section applies to outboard motors, jet skis, snowmobiles, and lawn-and-garden equipment.

The owner’s manuals of much small-engine equipment recommend that the gasoline be less than 30 days old. They also recommend that the equipment not be stored with gasoline in the fuel tank. The tank should be emptied and the equipment run until the fuel line and carburetor also are empty. Both recommendations are intended to protect essential fuel system parts from gum deposits. While Chevron gasoline is stable for much longer than 30 days, it is Chevron’s policy to defer to the recommendations of the equipment manufacturer.

Follow the fuel and storage recommendations in the owner’s manual for your equipment.

Even if it is not recommended, draining the fuel from the equipment is the preferred practice when it is easy to do.

If fuel is left in the equipment, follow the general storage recommendations.

Equipment with a two-stroke-cycle engine requires fuel that is a mixture of gasoline and oil. While this mixture is as stable as gasoline, Chevron recommends not preparing more than you can use in a month or two because disposing of any excess is not easy. The gasoline-oil mixture should not be added to the fuel tank of a gasoline-fueled four-stroke-cycle vehicle.
