RAVENOL USVO VollSynth Turbo VST 5W-40 Engine Oil is a PAO (Polyalphaolefin) based, fully synthetic low friction engine oil with our state-of-the-art unique USVO® and CleanSynto® technologies. It has full OEM approval from Mercedes-Benz, Porsche, Volkswagen, BMW and Renault, and is recommended for petrol and diesel engines with and without turbo-charging, direct injection and catalytic operation.

The USVO® technology makes it possible that the product has no shear losses during the entire oil change interval and is extremely stable to oxidation. This improves engine protection, efficiency and performance, engine cleanliness and extends oil drain intervals to the maximum recommended by the manufacturer. The high quality base oils also help the oil reach critical lubricating points faster, minimising friction and wear and providing excellent cold start characteristics. You can also view the results of an independent test HERE.

RAVENOL USVO VST 5W-40 Engine Oil utilizes the positive properties of tungsten to smooth the surface structure of the motor, significantly improving mechanical efficiency. This guarantees optimal operation in all driving conditions, extreme stop and go in heavy traffic to high speed driving on motorways.

USVO Technology

Ravenol has made it their mission to master the technological challenges of the future of lubricants and have therefore developed the ultimate in automotive lubrication technology......USVO® 

What is USVO® technology?

Lubricant requirements for modern vehicles are becoming increasingly demanding, with unwanted changes in viscosity quickly causing serious problems. To counter this, Ravenol has developed the USVO® lubricant technology to provide a very high viscosity stability at both high and low temperatures. To achieve this only the highest quality fully synthetic base oils and additives are used. USVO® stands for Ultra Strong Viscosity Oil.


• EXCELLENT HIGH TEMPERATURE VISCOSITY (HTHS AT 150 °C)Barely any viscosity loss during operation, which means that the lubricant film is permanently maintained during operation.
• EXCELLENT PERFORMANCE AT LOW TEMPERATURES (CCS AT -30 °C)The lubricant is always flows freely so that direct engine lubrication is guaranteed even for cold starts.
• VERY GOOD OXIDATION STABILITYOxidation stable lubricants have increased resistance against reacting with oxygen and temperatures. This increases the lubricant service life, which permanently prevents deposits (sludge) and maintains the lubrication properties.
• VERY LOW LOSSES DUE TO EVAPORATIONOnly a few components of the oil evaporate at the high operating temperatures. As a result, the engine oil level drops only slightly and the environment is not additionally polluted by the gases.
• HIGH VISCOSITY INDEXA high viscosity index illustrates a reduced temperature-dependent viscosity change compared to a low viscosity index.
• VERY LOW POUR POINTThe pour point is the lowest temperature above which an oil is liquid. As a result, lubrication is guaranteed, even at the lowest temperatures. Even if we never get temperatures this low in the UK, the lower the pour point, the better the quality of the lubricant.

Properties of the RAVENOL-USVO® qualities

Thanks to their technical properties, RAVENOL USVO® lubricants optimise engine performance and noticeably reduce fuel consumption at the same time. This benefits the environment, as lower fuel consumption leads to reduced CO2 emissions.

CCS = Low temperature viscosity

PP = Temperature of loss of fluidity

MRV = Low temperature viscosity when pumping through

SSI = Mechanical shear strength

Have found this particular Ravenol oil to be highly compatible with my old and original 1997 VW Mk3 Golf GTI 2.0l 16v car! Have only 68,450 miles on the clock and this German oil is perfect and made for the job! Will never use any other make of oil other than Ravenol in future to keep the heart of my engine in tip top shape!!!

Always great to see someone really caring for their car!

Quality product and a very professional quick service
31 August 2020  | 

Very pleasantly surprised by the quality of this product and indeed the time it took to the oil to arrive. Our Subaru Turbo sailed through emissions and when I drive her last night in the power mode she certainly picked up her skirts very strongly. I am very pleased with this package.

Been using this for a while, the Clean Synto stuff really does keep the engine running well and the mechanic always says its shiny and clean inside (just like the outside )
