RAVENOL USVO® RHP Racing High Performance 75W-90 Gear Oil is a modern, PAO (poly-alpha-olefin) based fully synthetic racing gear oil with USVO® Technology. It was developed for use as a manual and differential oil for use in racing vehicles and is particularly recommended for use in manual transmissions and rear axle with integrated locking differential.

The special additive package guarantee limited slip properties, a high load carrying capacity, stable viscosity, optimum wear protection, low foaming, proper lubrication and actually lowers the temperature of the transmission. The special formulation offers excellent thermal and shear stability, even under the most arduous and stressful conditions. 

RAVENOL RHP 75W-90 Gear Oil was tested at the Nürburgring and our partner circuit, the Hockenheimring. It is used and recommended by Opel Motorsport and our British Touring Car Championship partner team BTC Racing. It was also used by former WRC Co-driver Nicky Grist (who has partnered WRC legends such as Juha Kankkunen and Colin McRae) in his Toyota Celica at the Eifel Rally in Germany, who had this to say about it: "My Celica is all built and I run the car as a shakedown recently, and the gearbox has a much better gear change now that we have changed it over to RAVENOL."


RAVENOL RHP 75W-90 Gear Oil is designed for use in both synchromesh and non-synchromesh competition and motorsport gearboxes, as well as for very high performance road and track day applications. Especially suitable for high performance sequential transmissions, as well as for use in FWD applications where both a synchromesh gearbox and limited slip differential are using a common lubricant.


RAVENOL RHP 75W-90 Gear Oil offers:

  • A stable high-pressure lubricating oil film even at high temperatures.
  • Excellent shear stability for longer fluid life.
  • Outstanding thermal stability even when very highly stressed
  • An excellent aging resistance and high oxidation resistance.
  • Exceptional wear protection, with excellent EP characteristics.
  • Very low foaming tendency even at high speeds.
  • Compatible with all non-ferrous metals and all types of sealing materials.
  • Extended oil change intervals are possible, thanks to excellent shear stability
  • Small amount of friction modifier in the formulation ensures suitability for use in FWD applications where both synchromesh gearbox and limited slip differential are present and share a common lubricant.

All deliveries sent with DHL Parcels are supplied on a signature required service. If you have asked for the parcel to left in a safe place, we will convey this instruction to the courier but cannot guarantee this will be done as the service is a POD service and items left without signature are at the discretion of the driver. Please note that DHL Parcels may use sub-contract transport companies - we cannot therefor guarantee that specific instructions, especially requests for the driver to call beforehand, will be carried out. Please bear in mind that these drivers often have a hundred or more deliveries to make in one day!

If the customer requests delivery to be left in a 'safe place' we cannot be held responsible for loss.
