The synthetic formulation of Formula 4-Stroke Synthetic Scooter Oil effectively resists shear, delivering consistent viscosity protection for outstanding wear protection and long equipment life.<\/p>\n<hr \/>\n<p><strong><span class=\"a_GcMg font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none\">Thermal Stability<\/span><\/strong><\/p>\n<p>Scooter engine operating temperatures fluctuate greatly, especially in air-cooled engines. Formula 4-Stroke Synthetic Scooter Oil resists breakdown at elevated temperatures, maintaining its protective viscosity for maximum wear control.<\/p>\n<hr \/>\n<p class=\"cvGsUA block-font-kerning-none block-font-feature-liga-off block-font-feature-clig-off block-font-feature-calt-off direction-ltr align-start para-style-body\"><strong><span class=\"a_GcMg font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none\">Transmission and Gearbox Compatibility<\/span><\/strong><\/p>\n<p class=\"cvGsUA block-font-kerning-none block-font-feature-liga-off block-font-feature-clig-off block-font-feature-calt-off direction-ltr align-start para-style-body\">In many scooter applications, the engine, transmission and gearbox share the same oil reservoir. Formula 4-Stroke Synthetic Scooter Oil is shear stable and resists thinning from mechanical activity, providing superior protection for transmissions and gearboxes.<\/p>\n<hr \/>\n<p class=\"cvGsUA block-font-kerning-none block-font-feature-liga-off block-font-feature-clig-off block-font-feature-calt-off direction-ltr align-start para-style-body\"><strong><span class=\"a_GcMg font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none\">Wet-Clutch Compatibility<\/span><\/strong><\/p>\n<p class=\"cvGsUA block-font-kerning-none block-font-feature-liga-off block-font-feature-clig-off block-font-feature-calt-off direction-ltr align-start para-style-body\">Some scooters use a frictional clutch to engage and disengage the engine from the drivetrain. In many cases, this clutch is immersed in the same oil used in the engine and transmission. Formula 4-Stroke Synthetic Scooter Oil is wet-clutch compatible. It contains no friction modifiers, offering smooth clutch operation and increased clutch life.<\/p>\n<hr \/>\n<p class=\"cvGsUA block-font-kerning-none block-font-feature-liga-off block-font-feature-clig-off block-font-feature-calt-off direction-ltr align-start para-style-body\"><strong><span class=\"a_GcMg font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none\">Rust and Corrosion Protection<\/span><\/strong><\/p>\n<p class=\"cvGsUA block-font-kerning-none block-font-feature-liga-off block-font-feature-clig-off block-font-feature-calt-off direction-ltr align-start para-style-body\">Scooters are often subjected to extended periods of inactivity and storage, exposing the equipment to internal rust and corrosion.
