What You'll Learn
Ethanol in chainsaw fuel can destroy car engines
Ethanol is a gas additive that is now commonly found in the gas pumped from almost every gas station. The percentage of ethanol in the blend is indicated by the E number, for example, E10 means the gas mixture contains 10% ethanol. While ethanol fuel won't do much harm to car engines, it can cause issues when used in outdoor power equipment with small engines, such as lawn mowers, chainsaws, trimmers, and leaf blowers.
Ethanol is an excellent solvent with the ability to dissolve plastic, rubber, fiberglass, and more. This can lead to serious problems in small engines, such as those found in chainsaws. If the rubber parts in the fuel system are not made with ethanol-resistant materials, the ethanol can soften them, causing a gooey mess that clogs the carburetor. Additionally, ethanol can dissolve resin from fiberglass, commonly found in older built-in boat gas tanks, leading to clogged carburetors and filters.
To avoid these issues, it is recommended to use ethanol-free gas in small engine equipment. Some states, such as Massachusetts and Maine, require 10% ethanol in gasoline, making it difficult to avoid. However, there are options to mitigate the risks. One option is to use fuel additives that can help clean injectors and carburetors, such as Sea Foam. Another option is to adjust the carburetor for the fuel blend being used, ensuring it doesn't run lean. Using higher octane fuel, such as 93 octane instead of 89, can also provide extra insurance against detonation, a common concern with ethanol-blended fuels in 2-stroke engines.
It is worth noting that ethanol blends actually run cooler than straight gasoline, and some people have been using them without issue for decades. However, it is important to change the fuel lines when using ethanol blends as they can be damaged over time. Overall, while ethanol in chainsaw fuel may not immediately destroy car engines, it can cause significant damage to small engines, leading to costly repairs. Therefore, it is recommended to follow the manufacturer's guidelines and use ethanol-free fuel in outdoor power equipment with small engines.

Chainsaw fuel additives may not be suitable for cars
Secondly, chainsaw fuel additives often contain ethanol, which can be problematic for car engines. Ethanol has been known to dissolve rubber components in fuel systems, leading to clogged carbs and filters. Unless the car's fuel system is made with ethanol-resistant materials, it is advisable to avoid using ethanol-blended fuels or additives.
Additionally, some chainsaw fuel additives are designed to address specific issues common in chainsaws, such as carbon build-up or varnish in the carburetor. These additives may not provide any significant benefits to a car engine that is generally healthier and less prone to such issues. In such cases, the additive may simply be an unnecessary expense without any noticeable improvement in performance.
Furthermore, the use of fuel additives in cars should be approached with caution as some additives may not be suitable for all vehicles. It is essential to refer to the car manufacturer's recommendations and choose additives that are compatible with the specific make and model of the car. Using the wrong additive can potentially cause more harm than good.
Lastly, while chainsaw fuel additives can help maintain and improve the performance of chainsaws, they are not always necessary for cars. Proper maintenance, such as using high-quality fuel and regular servicing, can often be sufficient to keep a car's engine in good condition without the need for additional additives. In conclusion, while chainsaw fuel additives may offer benefits for chainsaws, they may not provide the same advantages for cars and could potentially cause issues if used incorrectly or with incompatible engines.

Chainsaw fuel is not meant to be left in the machine for long
It is not advisable to leave chainsaw fuel in the machine for extended periods, as it can cause operational issues and damage to the equipment. One of the primary concerns is the presence of ethanol in the fuel. Over time, ethanol can dissolve rubber components in the fuel system, leading to clogged carburetors and filters. This issue is particularly prevalent in chainsaws due to the small size of their carburetors.
Leaving fuel in the chainsaw for prolonged periods can result in starting problems, difficulty keeping the machine running, and a loss of power. These issues are often attributed to the settling of the "hi-test" oil in the gas-oil mixture, which becomes challenging to mix adequately in the small chainsaw tank. Additionally, old fuel can lose its volatility, making it harder to ignite and potentially causing carbon build-up in the engine.
To mitigate these problems, it is recommended to drain the chainsaw's fuel tank if the machine will be sitting for longer than a month. Some users opt to use fuel additives to address issues related to ethanol and old fuel. Sea Foam, for example, is known for its ability to clean injectors and carburetors, removing carbon and varnish deposits. However, others argue that these additives may not be necessary and can be expensive.
Instead of relying solely on additives, some users choose to use ethanol-free fuel in their chainsaws. This type of fuel does not evaporate like ethanol-blended gasoline and can be left in the machine for extended periods without causing harm. Additionally, proper storage practices are essential. Some users recommend leaving small-engine tanks dry when storing equipment for long periods, especially during winter months when usage decreases.
In conclusion, while chainsaw fuel additives may not necessarily destroy cars, it is generally recommended to avoid leaving fuel in the chainsaw for extended periods. Proper fuel management and storage practices can help prevent operational issues and maintain the longevity of the equipment. Regular maintenance, such as cleaning the carburetor and using fresh fuel, can also contribute to the overall health of the chainsaw's engine.

Chainsaw fuel stabilizers are used for seasonal storage
Fuel stabilizers are used to preserve the quality of gasoline or other fuels when stored for extended periods. They are suitable for all kinds of gasoline and diesel engines, including two-stroke motors as found in chainsaws.
Gasoline and diesel fuel are perishable, so before storing chainsaws for a month or more, it is a good idea to add a small amount of fuel stabilizer to the tank. This will help keep the fuel from becoming stale or oxidized and clogging up small ports in the fuel system. It will also help with water accumulation and allow old fuel to burn acceptably.
There are different types of fuel stabilizers available, including Sta-Bil, Star Tron, and Stabil. Sta-Bil, for example, has a specific product for non-leaded gasoline and another for ethanol gasoline. It is recommended to follow the directions on the bottle, but generally, a small amount of stabilizer is added to the fuel tank, and then the fuel is topped off. The engine is then started and allowed to run for 10 minutes so the stabilizer gets mixed with the fuel.
Some people choose not to use fuel stabilizers, opting instead to run their chainsaws dry and store them without fuel. This is because fuel stabilizers are not a miracle additive and fuel that is newer will always burn cleaner and easier. However, failing to use a stabilizer can mean poor performance or even engine failure after several months of storage.
In addition to fuel stabilizers, there are other fuel additives available that serve different purposes. For example, Sea Foam is a fuel additive that helps clean injectors and carbs, removing carbon and varnish build-up.

Chainsaw fuel can be used in cars without causing damage
Additionally, some high-performance chainsaw fuels contain lead, which can build up on piston crowns, valves, and exhaust ports. This build-up can cause problems if cylinder head temperatures are not high enough to burn off the lead during engine operation. To avoid this issue, it is recommended to maintain cylinder head temperatures of around 375 F.
Another consideration is the octane rating of the fuel. While higher octane ratings are associated with increased performance, they may not be necessary for all applications. For example, a user reports that they use 91 or 93 octane fuel in their chainsaw without issues, and Stihl, a power tool company, recommends a minimum of 89 octane and a maximum of E10 for their products.
Some chainsaw users also opt for pre-mixed fuels designed specifically for chainsaws, such as the Stihl High-Performance Mix or the Husky premixed fuel. These fuels eliminate the need to mix oil and gas separately and may be less likely to cause compatibility issues with the engine components.
In summary, chainsaw fuel can generally be used in cars without causing damage, but it is important to consider the specific fuel requirements of the chainsaw and the car, as well as the potential effects of ethanol and lead content on the engine components. Proper fuel storage and maintenance practices are also crucial to ensure the longevity of both the chainsaw and the vehicle.
