Japanese lubricant manufacturers were first to introduce low-viscosity engine oils in the market, in response to requirements by Japanese automakers. The adoption of low-viscosity engine oils is now becoming more widespread in the United States and Europe, to meet the requirements of newer engines of American and European automakers.
Eurol, the largest independent lubricant manufacturer in The Netherlands, based in Nijverdal, has introduced two low-viscosity engine oils recently, Eurol Elance FE 0W-20 and Eurol Ultrance ECO 0W-20.
Eurol Ultrance ECO 0W-20 is a full synthetic mid-SAPS* engine oil for passenger cars, vans and sport utility vehicles (SUVs) equipped with aftertreatment devices, with or without turbochargers. Eurol Ultrance ECO 0W-20 is available in one and five litre bottles, 20 litre Bag in Box, 60 litre drum and 210 litre drum.
Eurol Elance FE 0W-20 is a full synthetic mid-SAPS engine oil, formulated to comply with the Renault RN17 FE specification. Eurol Elance FE 0W-20 engine oil is suitable for specific gasoline and diesel engines (Euro 6d from mid-2018) from Renault and Dacia and for vehicles for which ACEA C5** is recommended. This product is available in one litre, 20 litre Bag in Box and 210 litre barrel.
Renault RN17 and RN17 FE are the latest service fill specifications for Renault’s gasoline and Euro 6 diesel engines. RN17 (ACEA C3) is for 5W-30, while RN17 FE (ACEA C5) is for 0W-20. FE denotes fuel efficiency.
In June 2018, Eurol introduced Elance 5W-30, a fully synthetic, long-life engine oil for petrol and diesel engines that meets Renault RN17, API SN, and ACEA C2 and C3.
“Renault, like most OEMs, are very keen to ensure they protect the environment as much as possible. So in order to do this, they brought out these new technologies, GPFs in particular, for the global marketplaces. And this new specification is compatible with those,” said Damien Browne, Lubrizol’s product manager, Consumer Engine Lubricants, in Lubrizol360.com.
The most important performance features of the RN17 specification are oxidation and piston cleanliness, said Joanne Jones, technology manager, Consumer Engine Lubricants, for Lubrizol. According to Jones, RN17 brings extra requirements in terms of sooted valve train wear performance, alongside the ACEA specifications which include soot performance, sludge performance, and wear performance, specifically for diesel engines. The addition of soot usually changes the wear behavior within a valve train, she said. “Renault decided they needed extra protection for their specification as the hardware design was slightly different to that contained within the basic ACEA sequences.”
“It is likely to become a very large volume and important specification going forward for Renault,” she added.
