  • Provides sustained engine power throughout the race
  • Visible spark plug and piston crown deposits to enable fine race tuning - high levels of deposits and good tones giving excellent readability on all unleaded fuels.
  • Wet weather throttle lubrication - Castrol POWER1 XR 77 is formulated to prevent throttle slide sticking during wet conditions
  • Ease of mixing with racing petrol - and minimal effect on the octane rating of high performance fuels allowing maximum engine compression

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.

How long will it take to get my order?
