AMSOIL Briggs & Stratton Synthetic 4T Racing Oil (GBS2960)

AMSOIL Briggs & Stratton Synthetic 4T Racing Oil was jointly developed by Briggs & Stratton engineers and AMSOIL to help maximize horsepower while handling the intense heat and shearing forces inside competition four-stroke engines. It’s specially engineered for high-revving, air-cooled racing engines without the shortcomings of automotive, PAG or conventional “karting” oils.

Key Benefits

• Formulated to reduce harmful heat

• Maximizes horsepower (combines the performance of a lite oil with the protection of a heavier oil)

• Inhibits foam to maintain a durable lubricating film at high rpm

• Resists corrosion between races and during storage

• Tested and validated by Briggs & Stratton and AMSOIL

Applications (Specifications / Approvals)

Use Briggs & Stratton Synthetic 4T Racing Oil in stock and modified small-displacement air-cooled racing engines used in kart, junior drag, quarter midget and other racing applications. It is recommended for any four-stroke air-cooled competition engine, whether single- or multi-cylinder, splash- or pressure-lubricated, including Briggs & Stratton V-Twin engines requiring the listed viscosity and lubricating properties. Synthetic 4T Racing Oil is recommended for alcohol- and gasoline-fueled engines. Compatible with mineral oils.

Recommendations

Do not mix with other oils when converting to Synthetic 4T Racing Oil. Drain the existing oil from the engine and refill with Synthetic 4T Racing Oil. Run engine at idle–low speeds for 2–3 minutes. Drain oil and refill with Synthetic 4T Racing Oil.

Change / Drain Interval (Service Life)

• Follow the original equipment manufacturer (OEM) or engine builder’s recommendations.

Note: Always confirm the correct oil requirements for your specific engine and racing class.
