EnerG Lubricants has received Mercedes-Benz approval under the MB 229.71 category for its EnerG G1 Sonic PLUS 0W-20 engine oil. Mercedes-Benz issued the certificate on 22 June 2026 to NDTH Energy, the New Delhi company behind the brand. This EnerG product also meets the API SQ and ACEA C6 performance grades.
The approval is EnerG's third from Mercedes-Benz. The brand earned its first two approvals for the MB 229.51 and MB 229.52 categories in November 2024 for the EnerG G1 Xtreme PLUS 5W-30. At the time, EnerG had partnered with the German additive maker GAT GmbH and launched a co-branded GAT x EnerG product range. With MB 229.71 now added, EnerG sits alongside HPCL as one of only two Indian-origin lubricant brands on the Mercedes-Benz-approved list for engine oils.
The MB 229.71 specification covers thin, low-viscosity 0W-20 oils for modern petrol and diesel engines. The earlier MB 229.51 and MB 229.52 categories, both built around the ACEA C3 standard, cover thicker 5W-30 oils for broadly the same engine types.
A Mercedes-Benz approval is demanding to earn and maintain. The oil has to pass the carmaker's own laboratory and engine tests, not simply match a specification on paper. It is not permanent either. The certificate is valid for up to five years and remains active only while the product stays listed on the Mercedes-Benz operating fluids website. EnerG, therefore, has to continue meeting the specification to retain the approval.
The company also holds a Volvo approval, received in August 2025. Its EnerG G Force XL 15W-40 heavy-duty engine oil carries Volvo's VDS-3 global certification, which placed NDTH, the parent company, among a small group of manufacturers worldwide cleared against Volvo's standards for commercial vehicle engines. Those standards cover longer oil-change intervals, lower engine wear and improved fuel efficiency.
