Synthetic Motor Oil, Gear Oil, ATF & Additives

Red Line

Red Line Synthetic Oil began in 1979 developing lubricants for the racing industry and now makes more than 100 products for automotive, motorcycle, marine and industrial use. Its motor oils, gear oils and powersports oils are built on a polyalphaolefin (PAO) and ester synthetic base with Red Line’s own additive chemistry, and the company describes its approach as PAO and ester engineered with proven performance. The high-performance motor oils carry enhanced ZDDP levels across 16 viscosities, from 0W20 to the 70Wt nitro oil; the gear oils include MTL and MT-90 manual transmission fluids and the ShockProof line for differentials and race gearboxes; the automatic transmission fluids cover domestic and import applications from street to racing; and WaterWetter, the cooling additive Red Line introduced, anchors its coolant products. The range also includes SI-1 fuel system cleaner and diesel additives, CV-2 and assembly greases, RL-600 DOT 4 brake fluid and power steering fluid. Most of what we carry is sold by the case — quarts and gallons packed as Red Line ships them — alongside 5-gallon pails and PowerPack kits.

All 130 products are chosen by specification, not by vehicle — oils, fluids and chemicals are selected by SAE viscosity, by API or GL rating and by container size, so they do not appear in the Part Finder. Every product page carries a Specifications list — match it to what your service manual calls for. Red Line does not publish a written consumer warranty; its technical line is (707) 745-6100.
