Using an upper cylinder lubricant can offer several benefits:

Lubrication:

E85 & Methanol has a lower lubricity compared to gasoline, which can lead to increased wear on engine components, especially in the upper cylinder area. The addition of an upper cylinder lube can help improve lubrication, reducing friction and wear on critical engine parts.

Valve Protection:

E85 & Methanol's lower lubricity can lead to increased valve seat and valve guide wear. An upper cylinder lube can help protect the valves and valve seats by providing a protective layer and reducing metal-to-metal contact.

Improved Performance:

By enhancing lubrication and reducing friction, an upper cylinder lube can contribute to improved engine performance. This may result in better acceleration, smoother operation, and potentially better fuel efficiency.

Preventing Corrosion:

E85 & Methanol is hygroscopic, meaning it readily absorbs moisture from the atmosphere. This moisture can lead to corrosion in the fuel system and engine. An upper cylinder lube may contain additives that help prevent or mitigate this corrosion, enhancing the durability of engine components.

Reduced Maintenance:

By protecting the engine from wear and corrosion, the use of an upper cylinder lube with pump E85 & methanol can potentially extend the life of engine components and reduce maintenance requirements.

Emission Reduction:

A smoother-operating engine with reduced wear is likely to have lower emissions. Additionally, some upper cylinder lubricants contain combustion-enhancing additives that may lead to more complete and cleaner combustion.

Cold Start Protection:

During cold starts, when engine components experience more wear due to reduced lubrication, an upper cylinder lube can offer added protection and reduce the impact of cold-start wear.

However, it's crucial to use an upper cylinder lubricant that is specifically formulated for use with methanol or other alcohol-based fuels. Not all upper cylinder lubes are suitable for use with alternative fuels, and using the wrong product may lead to undesirable effects or damage to the engine. Always follow the manufacturer's recommendations and use products that are compatible with the specific fuel being used. Additionally, keep in mind that some engines may have special lubrication requirements for running on methanol, and consulting with a qualified mechanic or the engine manufacturer is advisable.
