TECHNICAL FEATURES
0W20: Lightest road car motor oil produced by Red Line. Offers increased fuel economy and is very popular in small engines and hybrids.
0W30: Better flow at extremely cold temperatures compared to 5W30 and 10W30. Suitable for use where a 5W-30 is recommended.
0W20: Popular in Audi, Porsche and Mercedes-Benz applications. Better flow at extremely cold temperatures compared to 5W40 and 10W40.
5W20: The lightest multigrade street engine oil available from Red Line. Excellent performance in weather where cold starting and short running duration are concerns.
5W30: Provides the quickest starts and fastest oil pressure rise. Will reduce turbo lag and can provide more power and better fuel economy properly maintained engines. Thicker oil film at operating temperature than a petroleum 10W-40. Best choice for engines operated in extreme cold weather.
5W40: Reduces turbo lag and can provide more power and better fuel economy properly maintained engines, while providing 25% thicker oil films than a petroleum 5W40 or 10W40.
10W30: Best all-weather viscosity grade for gasoline engines in cars and light trucks that are driven on the street on a daily basis. Reduces turbo lag and provides more power and economy while providing thicker bearing oil films at operating temperature than a petroleum 10W-40. Best choice to replace a 5W-30 or 10W-30, petroleum-based or other-brand synthetic oil if maximum durability is preferred.
10W40: Best choice for engines that typically run high oil temperature or for engines in daily-driven vehicles regularly operated in hot weather. Best choice for high-performance engines that see street/strip or track activity. Features a thicker oil film at operating temperature than a petro-based 20W-50.
15W50: The ultimate high-temperature protection in Red Line engine oils recommended for street use. Provides 25% more viscosity in bearings than petroleum 20W-50s. Not recommended for use in cold climates where temperatures are at or below 10_F or -12_C or in production engines that see sustained oil temperatures below 225_F.
15W40 Diesel: Highly resistant to thermal breakdown. Provides double the detergent and acid-neutralizing ability of conventional petroleum diesel engine oils for maximum engine cleanliness. Ideal for diesels that run high oil temperature, such as those operated in hot weather or those in light truck applications where heavy loads are carried or towed. Best choice in medium and heavy-duty diesel truck engines when maximum durability is required. When used at extended drain intervals, it is an excellent value for long-haul, fleet use.
20W50: The ultimate high-temperature protection in Red Line engine oils recommended for street use. Provides 25% more viscosity in bearings than petroleum 20W-50s. Not recommended for use in cold climates where temperatures are at or below 10_F or -12_C. or in production engines that see sustained oil temperatures below 225_F.
