What type of gasoline do most snowmobiles require?

Most snowmobiles require unleaded gasoline because it is specifically formulated to prevent engine knocking and protect the internal components of the engine from damage. Unleaded gasoline provides adequate performance and efficiency without the harmful effects associated with lead additives found in some older fuel types. Additionally, using unleaded fuel is environmentally friendly and aligns with regulations regarding emissions, further enhancing its suitability for snowmobiles, which are often used in natural and recreational areas.

In contrast, premium gasoline is not typically necessary unless specified by the manufacturer's requirements for higher-performance models. Diesel fuel is not suitable for snowmobiles as they are designed with gasoline engines, and using diesel could result in significant engine damage. Mixed fuel is specifically used in two-stroke engines that require a mixture of oil and gasoline, which does not apply to the majority of modern snowmobiles that operate on standard gasoline.
