Does low test gas eat the gaskets in carburetor?

Low octane gasoline does not eat gaskets. Gasoline is a mixture of hydrocarbons, and the octane rating is a measure of its resistance to knocking. The higher the octane rating, the more resistant the gasoline is to knocking. Low octane gasoline can cause knocking, which can damage an engine, but it will not damage the gaskets.

Gaskets are made of a variety of materials, including rubber, cork, and metal. Rubber and cork gaskets are the most common type of gasket used in carburetors, and they are not affected by low octane gasoline. Metal gaskets are less common, but they can be damaged if they come in contact with low octane gasoline. However, this is not a common occurrence.
