Engine Oil

Diesel (3.0L V6 OM642 & 2.1L I4 OM651):

• Specification: MB-Approval 229.52
• Viscosity: SAE 5W-30

The single most important fluid for your diesel Sprinter is the engine oil. The MB 229.52 specification is a mandatory "Low SAPS" (Sulfated Ash, Phosphorus, and Sulfur) oil. This formulation is engineered specifically to protect the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems from contamination and clogging. Using a non-approved oil, such as a conventional heavy-duty diesel oil, will lead to rapid and irreversible damage to these expensive emissions components. The change interval is typically up to 20,000 miles, but this can be shortened by the van's service computer based on operating conditions.

Gasoline (2.0L I4 M274):

• Specification: MB-Approval 229.5
• Viscosity: SAE 5W-40 or 0W-40

The gasoline engine requires a full synthetic motor oil meeting the MB 229.5 standard. This spec ensures the oil can handle the high thermal stresses of the turbocharged, direct-injection engine while providing excellent lubrication and cleaning properties. Always verify the "MB-Approval 229.5" is printed on the bottle; do not confuse it with lesser specs like 229.3.

Engine Coolant

• Specification: MB 325.6 (Concentrate) or MB 326.6 (Pre-mixed 50/50)

Mercedes-Benz uses a specific Silicated Organic Acid Technology (Si-OAT) coolant, which is typically pink or violet in color. This advanced formula provides long-life protection for the mixed-metal components in the cooling system.

Common Pitfall: Never mix this coolant with other types. Adding green, orange, or yellow coolants (traditional IAT, OAT, or HOAT) can cause a chemical reaction that leads to gelling, blockages, and severe overheating. If a top-off is needed, use only distilled water in an emergency, and have the system flushed and refilled with the correct MB 325.6/326.6 fluid as soon as possible.

Automatic Transmission Fluid

• Specification: MB 236.15 (7G-Tronic) or MB 236.17 (9G-Tronic)
• Color: Often Blue/Green

The 2019 Sprinter was equipped with either a 7-speed or 9-speed automatic transmission, and they use different, non-interchangeable fluids. It is absolutely critical to verify which transmission your vehicle has before servicing. Using a generic "universal" ATF or the wrong specification will cause catastrophic failure. These are highly specific fluids engineered for the friction materials and hydraulic pressures of đỉnh-of-the-line Mercedes transmissions. The service interval is often around 60,000 miles and is crucial for smooth operation and longevity.

Drivetrain Fluids (4x4 & RWD)

Transfer Case (4x4 Models):

• Specification: MB 236.13 (an ATF-based fluid)
• Capacity: Approx. 1.8 Liters

The transfer case requires a specific fluid that provides lubrication for the chain and gearset. Do not substitute a generic gear oil.

Front & Rear Differentials:

• Front Axle (4x4): MB 235.7 / 235.74 (Typically SAE 75W-85)
• Rear Axle: MB 235.8 or MB 235.20 (Typically SAE 75W-90 or 75W-140 based on axle configuration)

Gear oil lubricates the hypoid gear sets in the differentials. The exact specification for the rear axle can vary depending on whether you have a standard or locking differential, and the axle's weight rating. Always cross-reference with your VIN or the tag on the differential housing. Using the wrong weight or a fluid without the proper friction modifiers (if required) can cause noise, chatter, and excessive wear.

Brake Fluid

• Specification: MB 331.0 (DOT 4+)

Mercedes-Benz specifies a "DOT 4+" brake fluid. This fluid has a higher wet and dry boiling point than standard DOT 4, providing an extra margin of safety under heavy braking conditions, such as descending a steep grade with a full load. The fluid should be flushed and replaced every two years, regardless of mileage, as it absorbs moisture from the atmosphere, which lowers its boiling point and can cause corrosion in the ABS/ESP hydraulic unit.

Power Steering Fluid

The 2019 Sprinter (VS30) is equipped with an Electric Power Steering (EPS) system. It does not have a hydraulic pump, reservoir, or fluid to check or change.

Diesel Exhaust Fluid (DEF)

• Specification: ISO 22241 (API Certified)

For diesel models, DEF (often sold under the brand name AdBlue®) is critical for the emissions system. It is a precise solution of 32.5% urea in 67.5% de-ionized water that is injected into the exhaust to neutralize NOx emissions. Only use high-quality, ISO 22241 certified DEF from a sealed container to avoid contaminating the sensitive SCR catalyst. The van provides ample warning before the DEF tank runs empty.

Windshield Washer Fluid

While any quality all-season washer fluid will work, Mercedes-Benz offers concentrated formulas (SummerFit and WinterFit) that are optimized for cleaning performance without clogging the spray nozzles.

Using the correct, manufacturer-specified fluid is the best insurance you can buy for your Sprinter. It ensures every component operates at peak performance and helps you avoid unexpected downtime.
