WOC OEMOFFICIAL

Clarity in an evolving Dexos™ market.

The European automotive aftermarket is navigating significant confusion regarding GM and Opel "Dexos2™" specifications. Wolf Oil Corporation solves this not by forcing a premature transition, but by offering a clear, segmented product architecture that protects existing volume while capturing the high-value future market across both diesel and petrol applications.

The Diesel Volume Protector

There are millions of legacy Opel and Vauxhall diesel vehicles on European roads that were engineered specifically for the higher High-Temperature High-Shear (HTHS) viscosity (≥ 3.5 cP) provided by a 5W-30 grade.

By maintaining the 5W-30 dexos2™ as a dedicated, active product, WOC serves the massive existing aftermarket demand. This prevents the confusion of forcing workshops into a Dexos D 5W-30 transition before they are ready, ensuring that mechanics have the exact, trusted, OEM Official formulation they need for the cars in their bays today.

The WOC Guarantee: Dexos 2 is not discontinued in Europe, and WOC guarantees its supply.

The Petrol Volume Protector

Parallel to the diesel fleet, a vast number of standard turbocharged gasoline direct-injection (TGDI) engines require the robust protection of a 5W-30 viscosity.

The 5W-30 dexos1™ Gen 3 serves as the volume protector for the petrol segment. It delivers critical Low-Speed Pre-Ignition (LSPI) protection, enhanced oxidation resistance, and sludge prevention for millions of GM and Opel petrol engines. This ensures workshops have the exact, OEM-approved 5W-30 petrol solution without compromising on the latest Gen 3 performance standards.

The Future-Ready Diesel Standard

The future of GM and Opel light-duty diesel engines (such as the 3.0L Duramax and newer European variants) strictly requires ultra-low viscosity oils to achieve stringent fuel economy and emissions compliance targets.

The 0W-20 dexos™D positions WOC for this future. It captures the growing market of modern diesels that demand a lower HTHS viscosity while maintaining robust protection for advanced exhaust after-treatment systems. It is the ultimate expression of WOC's molecule engineering capability, ready for the vehicles rolling off the production line today.

The Modern Petrol Solution

As European emission standards tightened, Opel and GM introduced modern, downsized TGDI engines designed specifically around ultra-low viscosity oils to maximize fuel efficiency.

The 0W-20 dexos1™ Gen 3 perfectly covers these modern petrol applications. It provides distributors with the exact right formulation for the newest GM petrol engines, ensuring that workshops do not compromise on LSPI protection while achieving the strict fuel economy and CO₂ emission targets engineered into the vehicle.
