Red Line's synthetic motor oils are designed to provide the highest protection, cleanliness and superior drain intervals with the lowest friction for your gasoline, diesel, motorcycle or marine engine. Red Line uses the most stable components available and formulate their products for wear protection and friction reduction across a wide range of engine operating conditions. Red Line's products are unique because they contain polyol ester base stocks, the only lubricants which can withstand the tremendous heat.

Offers improved fuel economy and popular for small engines and hybrids. It features a thicker oil film at operating temperature than a petro-based 5W-20. Suitable for use where a 5W-20 is recommended.
