Engine Oil

For your 2017 Mercedes-Benz Metris, equipped with the M274 2.0L turbocharged 4-cylinder gasoline engine, the factory-specified engine oil typically falls under Mercedes-Benz Specification MB 229.5. In some regions or for specific operating conditions, MB 229.3 may also be acceptable. It is crucial to use an engine oil that explicitly states compliance with these Mercedes-Benz approvals on the product label.

Regarding viscosity, common recommendations include 5W-40. However, always consult your owner's manual or the vehicle's service information system for the exact recommended viscosity grade for your specific climate and driving conditions. Using the incorrect viscosity can impact lubrication and fuel efficiency.

Capacity: The engine oil capacity for the M274 engine is approximately 7.0 to 7.5 liters during a filter change. Always fill to the appropriate level on the dipstick and do not overfill or underfill.

Intervals and Pitfalls: Mercedes-Benz generally recommends oil change intervals of 10,000 miles or one year, whichever comes first, for regular service. However, if your vehicle operates under severe conditions (e.g., extensive stop-and-go driving, towing, extreme temperatures), more frequent changes may be warranted. Never mix different types or brands of engine oil without verifying compatibility. Using non-approved oils can lead to premature wear, sludge formation, and potentially void your warranty. Always replace the oil filter with a new, high-quality filter designed for your vehicle.

Engine Coolant

mercedes-Benz specifies an ethylene-glycol-based coolant for the 2017 Metris that complies with Mercedes-Benz Specification MB 325.0 or MB 325.6 (for the corrosion inhibitor concentrate, which is then mixed with distilled water). This coolant is typically blue or blue-green in color. It is a Hybrid Organic Acid Technology (HOAT) or Silicate Hybrid Organic Acid Technology (Si-HOAT) type coolant.

Capacity: The cooling system capacity is approximately 9.5 to 10.5 liters.

Intervals and Pitfalls: Mercedes-Benz coolant is designed for long service life, often 10 years or 100,000 to 150,000 miles, but always check your maintenance schedule. The most critical pitfall is mixing different types of coolants. Never mix MB 325.0/325.6 coolant with conventional green coolants or Orange/Red OAT coolants (Organic Acid Technology). Mixing incompatible coolants can lead to chemical reactions, gel formation, corrosion, and severe damage to the cooling system and engine. Always use distilled water when mixing concentrate.

Transmission Fluid

The 2017 Mercedes-Benz Metris is likely equipped with either a 7G-Tronic (722.9) or a 7G-Tronic Plus (722.9) automatic transmission, or potentially a 722.6 transmission depending on the market and specific variant. For the 722.9 (7G-Tronic) transmissions, the required automatic transmission fluid (ATF) is specified under Mercedes-Benz MB 236.14. For the latest generation 7G-Tronic Plus and some newer applications, MB 236.15 fluid may be specified, which is a lower viscosity fluid. For the earlier 722.6 transmissions, MB 236.10 or MB 236.14 would be applicable. It is IMPERATIVE to verify the exact transmission code and corresponding fluid specification from your owner's manual or official Mercedes-Benz service documentation for your specific VIN.

Capacity: Transmission fluid capacity varies significantly between a simple drain-and-fill (typically 5.0-6.0 liters) and a complete system dry fill (which can be 9.0 liters or more). A complete flush and fill will require more fluid. Always ensure the fluid level is checked according to Mercedes-Benz procedures, often at a specific temperature.

Intervals and Pitfalls: Mercedes-Benz transmissions are considered "sealed for life" by some, but for optimal longevity, particularly in commercial or demanding applications, periodic fluid and filter changes are highly recommended. Intervals can range from 60,000 to 100,000 miles. Never use "universal" ATF or fluids that do not explicitly state compliance with the required Mercedes-Benz MB 236.xx specification. The wrong fluid can cause shuddering, hard shifts, premature wear, and catastrophic transmission failure. Always use genuine Mercedes-Benz fluid or an officially approved equivalent.

Differential Fluid

The 2017 Mercedes-Benz Metris is a rear-wheel-drive vehicle, meaning it has a rear differential. The factory-specified differential fluid is typically a hypoid gear oil meeting Mercedes-Benz specification MB 235.7. Other applicable specifications might include MB 235.74 or MB 235.61 for certain rear axle types or limited-slip differentials if equipped, though a limited-slip differential is uncommon on a Metris.

Capacity: The rear differential typically holds approximately 1.0 to 1.4 liters of gear oil. Always fill to the bottom of the fill plug hole.

Intervals and Pitfalls: Differential fluid is often considered a "lifetime" fill by some manufacturers, but in reality, it
