ACEA A/B Classification:

ACEA A1/B1 - Purpose: Petrol and diesel engines, light truck/particularly useful in engines that use oil with low friction and viscosity (Ford and Mazda) with a HTHS of 2.9 to 3,5MPa.s.
They are not suitable for certain types of motor, in case of doubt, please read the instructions.

ACEA A3/B3 - Purpose: Petrol engines of passenger cars and diesel light truck (extended oil change)/for engines, which use oils with low viscosity/engines operating in difficult conditions. In case of doubt, please read the manual.

ACEA A3/B4 - Purpose: Petrol and diesel engines with direct injection (common rail)/can also be used in the same situation as oil A3/3 as well, but these oils are recommended especially for an extended run.

ACEA A5/B5 - Purpose: Gasoline engines with high labor and diesel passenger cars and light commercial vehicles (using low viscosity oils with a HTHS of 2.9 to 3,5MPa.s.). Recommended when there were longer intervals in the exchange of oil and the extended run. They are not suitable for certain types of engine, in case of doubt, please read the manual.

ACEA C Classification:

ACEA C1 - Purpose: Catalytic converters in vehicles with DPF, FAP and TWC - engines of cars and diesel light trucks, as well as gasoline engines that require oils with low values of SAPS (low SAPS) and the HTHS higher than 2,9MPa.s.
They are not suitable for certain types of motor, in case of doubt, please read the instructions.

ACEA C2 - Purpose: catalytic converters in vehicles with DPF, FAP and TWC - engines of cars and diesel light trucks and petrol engines that require oils with average values SAPS (mid SAPS). For vehicles that can use oils with a low friction/low HTHS viscosity of greater than 2,9MPa.s.
They are not suitable for certain types of engine, in case of doubt, please read the manual or consult with a specialist.

ACEA C3 - Purpose: Catalytic converters in vehicles with DPF, FAP and TWC - engines of cars, gasoline and diesel light trucks, which require oils with average SAPS value (mid SAPS) and the HTHS higher than 3,5MPa.s.
They are not suitable for certain types of motor, in case of doubt, please read the instructions.

ACEA C4 - Purpose: engines of cars, gasoline and diesel light trucks, which require oils with low values of SAPS (low SAPS) and the HTHS higher than 3,5MPa.s.
They are not suitable for certain types of engine, in case of doubt, please read the
manual.
