ACEA C5 is a low-viscosity, mid-SAPS engine oil standard introduced in 2016 for modern gasoline and light-duty diesel engines fitted with emissions hardware like catalytic converters, DPFs, and GPFs. High-SAPS oils leave ash deposits that permanently block DPFs and poison catalysts. C5’s restricted sulphated ash, phosphorus, and sulphur levels prevent that. Its low HTHS viscosity (2.6 to 2.9 mPa·s) also reduces internal friction, which supports the fuel economy targets these engines were designed to meet. In some engines, particularly Jaguar Land Rover, oil also controls timing components hydraulically. The wrong oil can cause deposit buildup that makes those systems stick.
Where C5 Sits Relative to C6 and C7
ACEA C6 shares C5’s HTHS range but adds mandatory protection against Low-Speed Pre-Ignition (LSPI) and timing chain wear, both relevant concerns in turbocharged gasoline direct injection (GDI) engines. ACEA C7 pushes fuel economy further still with an even lower HTHS floor of 2.3 mPa·s, targeting the latest generation of ultra-efficient powertrains.
Which vehicles require ACEA C5
Several major manufacturers have written ACEA C5 into their official oil requirements. These are just some of the popular vehicle makers that require it:
- Jaguar Land Rover: STJLR.51.5122 and STJLR.03.5006, covering the AJ133 V8 and AJ126 V6 engines found in the F-Pace, F-Type, and XF.
- Volkswagen / Audi: VW 508 00 (gasoline) and VW 509 00 (diesel), for current eco-focused models. Owners can check the VW 508 00 approved oil list to find verified products that meet this factory standard.
- Mercedes-Benz: MB-Approval 229.71 and 229.72.
- BMW: Longlife-17 FE+, for the latest gasoline and light-duty diesel engines.
- Ford: WSS-M2C947-B1, WSS-M2C952-A1, and WSS-M2C962-A1.
- Volvo: VCC RBS0-2AE.
- Others: Fiat 9.55535-GSX, Chrysler MS-12145, and GM Dexos D.
Specific models that commonly require ACEA C5-aligned oils include the Honda Jazz Mk4 (2020 onward); and Land Cruiser Prado with the 2.8L turbo diesel, as well as select Hyundai and Kia models such as the Kona and Santa Fe. Very important: always confirm your vehicle’s exact oil specification in the owner’s manual before purchasing. Using the wrong ACEA grade, even a high-quality oil that meets a different spec, can damage your DPF or catalytic converter and shorten engine life.
Motor Oils that Meet ACEA C5
ACEA C5 oils are widely available from most major lubricant brands. If your vehicle calls for a European spec, it’s worth narrowing the list before looking at general-use options. Check out the best 0W-20 motor oil brands once you’ve confirmed what your engine actually requires. Here are the standout choices for European applications and what sets each apart.
Motul 8100 ECO-clean 0W-20
Motul 8100 ECO-clean 0W-20 Full Synthetic Motor Oil
Motul 8100 ECO-clean 0W-20 is a 100% synthetic ACEA C5/C6 oil built for modern engines that demand low-viscosity, mid-SAPS lubrication. It carries direct OEM approvals from BMW, Mercedes-Benz, and Jaguar Land Rover, making it a straightforward choice if your manufacturer requires one of those specs.
- Viscosity: SAE 0W-20
- HTHS: ≥ 2.6 mPa·s
- SAPS: Mid-SAPS (ash ≤ 0.8%, phosphorus 0.07–0.09%, sulphur ≤ 0.3%)

Technical Specifications for ACEA C5
ACEA C5 defines a stable, stay-in-grade oil for high-performance gasoline and light-duty diesel engines equipped with emissions hardware including Three-Way Catalysts (TWC) and Diesel or Gasoline Particulate Filters (DPF/GPF).
Key Physical and Chemical Parameters
The specification’s defining characteristic is its HTHS viscosity range of 2.6 to 2.9 mPa·s. High Temperature/High Shear (HTHS) viscosity measures oil film strength under the extreme conditions inside a running engine. Keeping it within this range reduces internal friction, which directly supports fuel economy and lower CO2 output. As a mid-SAPS oil, C5 restricts the chemical compounds most damaging to emissions hardware. Sulphated ash is capped at 0.8% m/m to prevent non-combustible deposits from blocking DPFs. Phosphorus is held between 0.070% and 0.090% m/m to avoid catalytic converter poisoning. Sulphur is limited to 0.3% m/m. Evaporative loss via the Noack test must stay at or below 13%, ensuring the oil doesn’t cook off under sustained heat. Total Base Number (TBN) must reach at least 6.0 mgKOH/g, which reflects the oil’s capacity to neutralize acidic combustion byproducts over its service life.
Performance and Durability Testing
Fuel economy improvement must reach at least 3.0% compared to a reference oil, typically measured using the M111 fuel economy test. Valvetrain wear is evaluated through the Sequence IVB test using a Toyota 2NR-FE engine, with cam wear limits set at 120 µm for outlet and 100 µm for inlet. Diesel engine wear is measured via the OM646LA test, with cylinder wear capped at 5.0 µm and bore polishing at 3.0 µm. Engine cleanliness is assessed through piston cleanliness tests using the VW TDI diesel platform and the EP6CDT gasoline direct injection engine. Low-temperature sludge resistance is tested via the Sequence VH, and black sludge performance through the M271 EVO test. C5 oils must also demonstrate oxidation stability and compatibility with biofuels to maintain protection across extended drain intervals.
Closing Notes
If your car requires ACEA C5, the right oil is required. Using the wrong grade risks clogging your DPF, poisoning your catalytic converter, damaging timing components, and voiding your warranty. Always check your owner’s manual for the exact specification, not just the viscosity on the cap. Then flip the bottle over and confirm it explicitly lists ACEA C5 or your manufacturer’s approval code. Any full synthetic 0W-20 won’t do. The approval on the label is what matters.
