RED LINE 20WT High Performance Synthetic Racing SAE20 (5w-20)

Red Line Racing Oils have a global reputation as the ultimate racing lubricant.

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.

  • To reduce the chance of detonation, Red Line race oils contain very few detergents and are not recommended for street use.
  • Remember to change these oils more frequently than regular motor oils

Redline Race 20WT engine oil is for drag racing, circle track qualifying, and racing engines designed for low-viscosity oils. Many drag racers run this oil for 10 to 12 passes before changing, with no sign of shear or loss of viscosity. Redline 20 WT Race Engine Oil offers ultimate protection and power for high performance engines.

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.
