The Mercedes — Benz M130.981 is a 5,987 cc, V8, naturally aspirated petrol engine produced between 1998 and 2002. It features a 32 — valve, DOHC configuration with Bosch LH — Jetronic fuel injection and electronic ignition. This high — displacement engine delivers smooth, linear power delivery and refined performance, characteristic of Mercedes — Benz's flagship luxury sedans and coupes of the era.
Fitted to the W220 S — Class (S 500), R170 SLK — Class (SLK 55 AMG), and C215 C…
All production years 1998–2002 meet Euro 3 emissions standards (VCA UK Type Approval #VCA/EMS/5681).
The Mercedes-Benz M130.981 is a 5,987 cc V8 naturally aspirated engine engineered for flagship luxury sedans and coupes (1998–2002). It combines 32-valve DOHC architecture with Bosch LH-Jetronic fuel injection to deliver seamless, high-torque performance. Designed to meet Euro 3 standards, it balances grand touring refinement with strong, linear power delivery.

The Mercedes-Benz M130.981 was used across Mercedes-Benz's W220/R170/C215 platforms with longitudinal mounting. This engine received platform-specific tuning-adapted throttle response in the R170 and revised cooling layouts in the W220-and from 2000, updated camshaft profiles and bearing materials per SIB 07.0123, creating service part interchange limits. All adaptations are documented in OEM technical bulletins.
The M130.981's primary reliability risk is camshaft wear on early builds, with elevated incidence in high-RPM operation. Internal Mercedes quality reports from 1999 indicated a significant portion of pre-2000 engines required cam replacement before 180,000 km, while VCA data shows a notable share of emissions failures linked to misfires from worn lobes. Sustained high speeds and extended oil intervals increase lobe and follower stress, making oil quality and adherence to MB 229.1 specification critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M130.981 offers smooth, powerful performance but early models (1998-1999) are prone to camshaft wear. Later revisions (post-2000) with upgraded components significantly improve durability. Regular maintenance, strict use of 20W-50 MB 229.1 oil, and timely camshaft upgrades are essential for long-term reliability.
Key issues include camshaft lobe wear (especially pre-2000), coolant leaks from aging hoses and manifolds, distributor cap/rotor failure causing misfires, and vacuum leaks from hardened hoses. These are documented in Mercedes service bulletins and are manageable with preventative maintenance.
This 6.0L V8 was used in flagship models: the W220 S-Class (S 500), R170 SLK-Class (SLK 55 AMG), and C215 CL-Class (CL 500) from 1998 to 2002. It replaced the M119 V8 and was succeeded by the twin-turbo M113 engine.
Limited tuning potential exists. ECU remapping is rare due to analog fuel injection (LH-Jetronic). Performance gains are typically achieved through exhaust, intake, and ignition upgrades. However, the engine's high-displacement nature and robust internals allow for modest increases, but over-revving without proper maintenance risks camshaft damage.
Fuel consumption is high by modern standards. In an S 500, expect ~18.0 L/100km (city) and ~12.0 L/100km (highway), or approximately 15–20 mpg UK. Real-world figures depend heavily on driving style, but this V8 prioritizes performance and refinement over economy.
Yes. The M130 series is an interference engine. If the timing chain fails or jumps, pistons can collide with open valves, resulting in catastrophic internal damage. Regular inspection of the chain and tensioner is crucial to prevent expensive repairs.
Mercedes specifies 20W-50 oil meeting MB 229.1 specification. This high-viscosity oil is essential for maintaining oil pressure and protecting camshafts and bearings under high-RPM operation. Oil changes should be performed every 15,000 km or annually to ensure optimal lubrication and longevity.
