Ummm, yes there is ... revised by ACEA 2016 / 2018. C5 is the 20 grade Euro oil spec. Mobil 1 ESP 0w20 X2 is C5.
C: Catalyst & GPF/DPF compatible Engine Oils for Gasoline & Diesel Engines - "Low SAPS"
Note: These Oils will increase the DPF/GPF and TWC life and maintain the Vehicle's Fuel Economy.
Warning: Some of these Categories may be unsuitable for use in certain Engine Types - consult the vehicle- OEM's owner's manual/handbook in case of doubt.
C1 Stable, stay-in-grade Engine Oil with Lowest SAPS-Level, intended for use as catalyst compatible Oil at extended Drain Intervals in Vehicles with all Types of modern Aftertreatment Systems and High Performance Passenger Car & Light Duty Van Gasoline & DI Diesel Engines that are designed to be capable of using Low Viscosity Oils with a minimum HTHS Viscosity of 2.9 mPaâ‹…s.
C2 Stable, stay-in-grade Engine Oil with Mid SAPS-Level, intended for use as catalyst compatible Oil at extended Drain Intervals in Vehicles with all Types of modern Aftertreatment Systems and High Performance Passenger Car & Light Duty Van Gasoline & DI Diesel Engines that are designed to be capable of using Low Viscosity Oils with a minimum HTHS Viscosity of 2.9 mPaâ‹…s.
C3 Stable, stay-in-grade Engine Oil with Mid SAPS-Level, intended for use as catalyst compatible Oil at extended Drain Intervals in Vehicles with all Types of modern Aftertreatment Systems and High Performance Passenger Car & Light Duty Van Gasoline & DI Diesel Engines that are designed to be capable of using Oils with a minimum HTHS Viscosity of 3.5 mPaâ‹…s.
C4 Stable, stay-in-grade Engine Oil with Low SAPS-Level, intended for use as catalyst compatible Oil at extended Drain Intervals in Vehicles with all Types of modern Aftertreatment Systems and High Performance Passenger Car & Light Duty Van Gasoline & DI Diesel Engines that are designed to be capable of using Oils with a minimum HTHS Viscosity of 3.5 mPaâ‹…s.
C5 Stable, stay-in-grade Engine Oil with Mid SAPS-Level, for further improved Fuel Economy, intended for use as catalyst compatible Oil at extended Drain Intervals in Vehicles with all Types of modern Aftertreatment Systems and High Performance Passenger Car & Light Duty Van Gasoline & DI Diesel Engines that are designed to be capable and OEM-approved for use of Low Viscosity Oils with a minimum HTHS Viscosity of 2.6 mPaâ‹…s.
SAPS: Sulphated Ash, Phosphorus, Sulphur
HTHS: High Temperature High Shear Viscosity
DI: Direct Injection
DPF: Diesel Particle Filter
GPF: Gasoline Particle Filter
TWC: Three-Way Catalyst
Ummm, no there is not. ACEA C specifications are specific to engines, not development. There are updated sequences within that same specification that you wrongly indicated as further development. C2 and higher does not mean it is better or more suitable for a car. C2 is lower HTHS for example than C3. Just because 3 is higher than 2 DOES NOT mean it is suitable for a specific car where ACEA C2 is specified. On that note, most European diesel, and when I say most, I mean 80% at least, are specified for ACEA C3. That does not mean they could use C4 or C5.
On this note, Hyundai has same language for ACEA A3 oils. I am not sure in which universe ACEA A5 is compatible with ACEA A3, but in this in which we live in, it is not.
By the way, I know all those shortcuts. I worked on development of C3 oil. People who employed me thought I should know those things.
