Red Line 10W40 Engine OIl $10.95 Per quart
Red Line 10W40 Is the best choice for engines that typically run high oil temperature. Use in engines for daily drivers operated in very hot weather on a regular basis. Also use in high-performance engines that see street as well as frequent racetrack duty. Thicker oil film at operating temperature than a petro-based 20W-50. While Red Line Synthetic Engine Oils are derived from Race Oils and are used by many racers, they were formulated specifically for street use in all kinds of passenger cars. Red Line Engine Oils outperform all petroleum-based oils and all other synthetics on the market today.
Red Line Engine Oils are designed to provide highest performance, best durability, ultimate protection and outstanding cleanliness along with lowest friction.
Red Line uses the most stable synthetic lubricant base stocks available and formulates products for wear protection and friction reduction across a wide range of engine operating conditions. Red Line lubricants are unique because they contain polyester base stocks, the only lubricant base stock type that withstands the incredible heat present in the hot sections of jet engines.
This high-temperature stability makes Red Line Engine Oils a necessity for proper lubrication of high-performance engines, turbo-charged engines, or any engine that runs high engine oil temperature. Red Line is not just for high-performance and racing. Ordinary cars and trucks that see “daily driver” duty benefit greatly when their engines are lubricated with Red Line engine oils. More performance, better fuel economy and increased durability come with use of our oils in daily drivers.
Because of the robust polyester base stock and high-performance anticorrosive additive package in Red Line oils, they are ideal for use in street-driven vehicles at extended drain intervals. Red Line recommends oil changes for engines that are in good condition and do not see frequent starts without warm-ups or short-trips at between 10,000 and 18,000 miles, or every 12 months, whichever is shorter.
