Red Line's 40 WT SAE (15W40) Racing Oil is for use where
temperatures may be high and when a wide range in RPMs and speeds
will be encountered. Red Line's Racing Oils have a global
reputation as the ultimate racing lubricant--many teams who have
found that the improved performance and equipment durability is the
key to winning. Red line's oils are made with the most thermally
stable synthetic base stocks available and provide the best
high-temperature lubrication and a higher film strength than any
petroleum or synthetic on the market today. Although Red Line
racing oils are categorized as straight grades, their
low-temperature properties make them exceptional multigrades,
allowing 2-4% more power than an oil of similar viscosity, while
providing much more protection. Each reduction in viscosity grade
allows 1-2% more power. To reduce the chance of detonation, Red
Line's race oils contain very few detergents and are not
recommended for street use. Red Line Synthetic Motor Oils are
designed to provide the highest degree of protection and
cleanliness for your engine. Red Line uses the most stable
synthetic components available and formulates their products for
wear protection across a wide range of operating conditions. Red
Line lubricants contain polyol ester basestocks, the only
lubricants which can withstand the tremendous heat of modern jet
engines, which makes our motor oil a necessity to properly
lubricate a turbocharger or hot-running engine. The synthetic
basestocks have a natural multigrade property, which means that
large amounts of unstable polymeric thickeners are not required to
manufacture our multigrades. Red Line Synthetic Motor Oils will
provide better protection than a petroleum oil of the next higher
viscosity grade under high shear conditions.
The quality of the product is as expected and delivery was fast. Will be visiting Autoplicity.com in the near future.

Did not receive any confirmation emails. However contacted them VIA chat and they provided me with information. Shipping is on the slower side.
