GM (OPEL) SPECIFICATIONS
The manufacturer requires for all vehicles the European specifications ACEA A3-98 and B3-98 with different viscosimetric grades - SAE 0/5/10 W - 30/40 with oil change at 15 thousand km or 1 year with Euro 2 engines (manufactured before 2001) and 30 thousand km or 1 year with Euro 3 engines.
In 2002 Opel also introduced the Opel Long Life Service Oils (starting from the Vectra model year 2002), a variable oil change interval that can reach 30 thousand km or 2 years for petrol engines (specification GM-LL-B-025) and 50 thousand km or 2 years for diesels 2.0 and 2.2 DTI (GM-LL-A-025).
The cars that use Opel Long Life Service Oils must pass ACEA specifications A3, B3, B4 and Opel tests B040 2095 HTHS >2.9 and B040 2098 for lubricants with HTHS >3.5.
This lubricant qualification system has been developed with the support of independent German laboratories who perform engine tests (for wear, deposits and F.E.) or tribological ones, using Opelís procedures.
