Millers Oils CRX 75w-90 NT+ Competition Fully synthetic transmission oil

Competition fully synthetic transmission oil. A blend of full synthetic base oils incorporating new “Nano Technology” additive chemistry to significantly reduce internal frictional and power losses. Competition grade transmission oils which are available in various viscosities and are formulated using a unique combination of improved chemistry and lower friction NANODRIVE additives to massively reduce friction vs a standard oil.

Designed for the lubrication of competition gearboxes. Manual transmissions, synchromesh, non-synchromesh, sequential gearboxes, transfer gearboxes, transaxles and hypoid differentials without limited slip which require API GL4 or GL5 performance.

Recommended for modern transmissions where full synthetic oil is specified, especially for high performance road and track day applications. Hewland, Xtrac, Glebe Transmissions, ZF, Tran X, Elite Transmissions.

Note: Does not contain friction modifiers. For plate type Limited Slip differentials use CRX LS 75w90 NT.

SHIPPING IS FREE* for orders of £60 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 £4.99 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.
