AMSOIL Gasoline StabilizerFights Gasoline Deterioration For Sure-Starts Every Time

Today’s gasoline formulas are not designed for long periods of inactivity. By month two of storage, serious degradation has begun and when it comes time to bring the vehicle or equipment back into service, fuel lines and carbs or injectors can be gummed up. Fight stale fuel with AMSOIL Gasoline Stabilizer. This Stabilizer’s potent anti-oxidant formula keeps gasoline fresh over extended periods of storage.

Is it Better to Drain Gas Tanks or Keep Them Full of Stabilized Fuel?

The answer is to keep the tank full of fresh gasoline treated with AMSOIL Gasoline Stabilizer. Here’s why:

  • Empty or partially filled fuel tanks can be vulnerable to condensation during shifts in the weather. This can add moisture to the fuel and contribute to the formation of gummy deposits. In steel fuel tanks, this condensation can form rust.
  • When equipment is drained and completely run out of gas for storage, what’s left is a dried out environment for gasket material, seals and o-rings. These items can shrink, crack and degrade over time. A far better solution is to thoroughly run stabilized fuel though the engine before long term shut down.
  • The dry environment of an engine completely emptied of gas leaves engine internals vulnerable to corrosion. The anti-oxidant formula of AMSOIL Gasoline Stabilizer protects engine surfaces from corrosion.

What is Worst Way to Store Gas-Powered Equipment?

The absolute worst way to store equipment is with non-stabilized fuel in the gas tank and fuel system. Gasoline starts to degrade after 30 days. After a few months, the gasoline will be completely stale. The degraded fuel can clog carburetors, fuel injectors and fuel lines with gummy deposits. When it comes time to start the engine again, operation will be poor (if it starts at all). Small engine repair shops love this storage method because repairs resulting from stale gasoline make up a large percentage of their annual work orders.

Oildepot Tip: Stabilize Gasoline During the Season as Well

The practice of adding gas stabilizer is definitely not just for off-season storage. We stabilize every can of fuel that we bring home for our snow blower or lawn equipment. As it can sometimes take longer than a month to consume a complete batch, we want to be sure that the fuel is always fresh. If you have a motorcycle, boat or snowmobile that is only used from time to time, stabilizing the gasoline is a smart maintenance practice. This advice does not apply to cars and trucks that run on a regular basis, but it certainly could apply to hobby cars that only run every few weeks.

For in-season gas stability, we use AMSOIL Quickshot Small Engine Gas Additive. It provides mid-term gas stability, fuel system cleaners and additives that neutralize potential ethanol problems. We use AMSOIL Gas Stabilizer when the equipment is about to be stored for the off-season. Gas Stabilizer is certainly fine for “in-season” use as well.
