40 WT SAE (15W40) is for use where temperatures may be high and when a wide range in RPMs and speeds will be encountered.
Oil Formulated for Racing
Red Line Synthetic Racing Oil is globally known as the ultimate racing lubricant and a key factor in getting a win! Formulated with the most thermally-stable synthetic base stocks available, this racing-blend oil contains fewer detergents to improve lubricity and reduce detonation. The low-temperature properties of this multi-grade racing lubricant allow a 2-4 percent increase in power compared to an oil of similar viscosity. Each reduction in viscosity grade allows 1-2 percent more power while providing much more protection. Additional features include improved startup protection, lower oil temps, no less than 2200 ppm of zinc, and phosphorus for protection against wear.
Note: Frequent oil changes are necessary. This oil is not suitable for street use.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
