BMW B46/B48 0W-20 Oil Change Guide – 230i, 330i, 430i & 530i

BMW's modern B46 and B48 2.0-liter turbocharged four-cylinder engines are used across a wide range of BMW models, including the 230i, 330i, 330e, 430i and 530i.

These engines combine turbocharging, direct injection and modern emissions technology, making correct engine-oil selection and regular filter replacement especially important.

For compatible applications, the Liqui Moly Top Tec 6600 0W-20 BMW Oil Change Kit combines 6 liters of Liqui Moly Top Tec 6600 SAE 0W-20 with a MAHLE OX 813/2D oil filter and applicable service sealing components.

Why Oil Maintenance Matters on BMW B46 & B48 Engines

The B46 and B48 are modern turbocharged engines that place significant demands on their lubrication systems.

Engine oil must protect internal components while also lubricating the turbocharger and maintaining stable performance across a broad range of operating temperatures.

Fresh, specification-correct engine oil helps support:

• Turbocharger lubrication
• Internal engine wear protection
• Cold-start lubrication
• Engine cleanliness
• Stable lubrication at operating temperature
• Reduced internal friction
• Protection during high-load operation

The oil filter is equally important because it removes contaminants from the oil as it circulates through the engine.

For this reason, engine oil and the oil filter should be treated as a complete maintenance system rather than separate components.

Why Liqui Moly Top Tec 6600 0W-20?

Liqui Moly Top Tec 6600 SAE 0W-20 is formulated for modern, fuel-efficient engines requiring a low-viscosity lubricant.

One of its most important characteristics for compatible BMW applications is its official:

BMW Longlife-17 FE+ Approval

Liqui Moly currently lists BMW Longlife-17 FE+, ACEA C5/C6, API SQ and ILSAC GF-7A among the specifications and approvals for Top Tec 6600 0W-20.

Liqui Moly also highlights characteristics including excellent wear protection, high lubrication reliability, engine cleanliness, high shear stability and suitability for turbochargers and catalytic converters.

For owners preparing for maintenance, the complete BMW B46/B48 Liqui Moly 0W-20 Oil Change Kit puts the primary oil-service components together in one package.

What's Included in the Oil Change Kit?

Oil Filter Brand: MAHLE

This kit uses a MAHLE cartridge-style oil filter, rather than an unidentified generic filtration component.

Manufacturer: MAHLE
MAHLE Part Number: OX 813/2D
BMW OE Reference: 11428575211

MAHLE documentation cross-references OX 813/2D to BMW OE number 11428575211.

BMW B46/B48 Vehicle Applications

Compatible applications can include:

Always verify the vehicle's year, model, engine, production date and VIN before purchasing service components.

BMW 230i Oil Change

The BMW 230i combines a compact chassis with BMW's turbocharged 2.0-liter four-cylinder engine.

For compatible B46/B48 applications, choosing an engine oil carrying the appropriate BMW specification is more important than simply selecting any bottle labeled 0W-20.

The BMW 230i Liqui Moly Top Tec 6600 Oil Change Kit provides 6 liters of 0W-20 oil together with a MAHLE OX 813/2D filter for compatible applications.

BMW 330i Oil Change

The BMW 330i is one of the most common applications associated with the modern turbocharged four-cylinder BMW platform.

Whether servicing a rear-wheel-drive 330i or compatible 330i xDrive, oil maintenance should include both fresh engine oil and a new filter.

For compatible applications, the BMW 330i 0W-20 Oil Change Kit with MAHLE Filter provides the primary service components together.

BMW 330e Oil Change

The BMW 330e combines a turbocharged gasoline engine with an electric drive system.

Although it is a plug-in hybrid, the internal-combustion engine still requires routine engine-oil and filter maintenance.

Hybrid operation can create different engine-use patterns compared with a conventional gasoline vehicle, but correct oil specification remains important.

Always confirm the exact production date and engine configuration when ordering components for a 330e.

BMW 430i Oil Change

Compatible 430i applications include multiple body styles, such as the Coupe, Convertible and Gran Coupe, as well as xDrive configurations.

The shared engine family can result in overlapping maintenance components, but body style or model designation alone should never be used to guarantee fitment.

For compatible vehicles, the BMW 430i Liqui Moly 0W-20 Oil Change Kit combines Top Tec 6600 with the MAHLE filtration component required for this package.

BMW 530i Oil Change

The G30-generation BMW 530i also uses BMW's turbocharged 2.0-liter four-cylinder architecture in applicable configurations.

Despite being part of the larger 5 Series family, its engine-maintenance requirements can overlap with other BMW models using related B46/B48 engines.

This is why searching by engine family and OEM component reference can be useful in addition to searching by model.

For compatible vehicles, the BMW 530i Top Tec 6600 0W-20 Oil Change Kit provides a convenient oil-and-filter maintenance package.

What Is BMW Longlife-17 FE+?

One of the most important things to understand when shopping for BMW engine oil is that viscosity and manufacturer approval are not the same thing.

0W-20 = SAE viscosity grade

BMW Longlife-17 FE+ = BMW engine-oil specification

Two oils can both carry a 0W-20 viscosity grade without carrying the same BMW approval.

Liqui Moly officially lists BMW Longlife-17 FE+ approval for Top Tec 6600 SAE 0W-20.

This is why simply searching for "BMW 0W-20 oil" is not always sufficient.

The correct oil should be selected according to the specifications required for the particular engine and vehicle.

What Does 0W-20 Mean?

0W-20 describes the engine oil's SAE viscosity grade.

The 0W portion relates to low-temperature viscosity characteristics, while 20 identifies its high-temperature viscosity grade.

Modern engines can be designed around lower-viscosity oils to help reduce internal friction and improve efficiency while still providing the required lubrication performance.

However, 0W-20 alone does not establish BMW compatibility.

The manufacturer's required specification must also be considered.

BMW LL-17 FE+ vs BMW LL-01

This distinction becomes particularly important when comparing newer BMWs with some of the older models we've covered.

Many earlier BMW applications use oils carrying BMW Longlife-01 (LL-01) approval.

This Top Tec 6600 package is centered around:

BMW Longlife-17 FE+

Therefore, don't assume that a BMW oil is interchangeable simply because both products come from the same manufacturer.

For example:

Liqui Moly Leichtlauf High Tech 5W-40 → BMW LL-01

Liqui Moly Top Tec 6600 0W-20 → BMW LL-17 FE+

They serve different application requirements.

Why the Turbocharger Makes Oil Maintenance Important

BMW's B46 and B48 engines use turbocharging to generate strong performance from a relatively compact 2.0-liter engine.

The turbocharger depends on engine oil for lubrication.

This means the oil has to perform reliably in an environment involving:

• High turbocharger speeds
• Significant operating temperatures
• Frequent temperature changes
• Cold starts
• Stop-and-go driving
• Extended highway operation
• High engine loads

Using the appropriate oil and maintaining sensible service intervals are fundamental parts of turbocharged-engine maintenance.

Why Use a MAHLE Oil Filter?

Engine oil is only one half of an oil service.

The filter removes contaminants from the lubricant as it circulates through the engine.

This kit uses:

MAHLE OX 813/2D

with:

BMW OE Reference 11428575211

MAHLE is a major automotive filtration and engine-component manufacturer.

Using a properly specified filter helps maintain the required filtration performance and oil flow characteristics.

The SayParts BMW B46/B48 Oil Change Kit therefore combines Liqui Moly oil and MAHLE filtration rather than requiring the owner to source the primary service components individually.

Understanding the Part Numbers

Three different identifiers may appear when purchasing this kit:

BMW OE: 11428575211

MAHLE: OX 813/2D

SayParts: SP-BMW-B46B48-LM6600-0W20-6L-MAHLE

These numbers serve different purposes.

The BMW number is the OEM component reference.

OX 813/2D identifies the MAHLE filter.

The SP number identifies the complete SayParts maintenance kit.

Keeping these references separate makes it easier to verify components and vehicle compatibility.

How Much Oil Is Included?

This package contains:

5L + 1L = 6 Liters

of Liqui Moly Top Tec 6600 SAE 0W-20.

However, 6 liters is the quantity supplied with the kit and should not automatically be interpreted as the exact engine refill capacity.

The exact amount required can vary according to engine and vehicle configuration.

Follow the appropriate service procedure for your BMW and verify the final engine-oil level after completing the service.

Basic BMW B46/B48 Oil Change Procedure

A typical oil service begins by safely preparing the vehicle and draining the used engine oil.

Remove the existing cartridge oil filter and install the new MAHLE OX 813/2D filter.

The applicable O-ring should also be replaced. Lightly lubricate the new O-ring with clean engine oil before installation and make sure it is correctly positioned.

After reinstalling the required drain components, refill the engine with the appropriate quantity of fresh oil.

Once the service is complete:

• Start the engine
• Allow oil to circulate
• Inspect the filter housing
• Inspect the drain area
• Check for leaks
• Verify the engine-oil level
• Correct the level if necessary

Always use the appropriate BMW service procedure and torque specifications for your exact vehicle.

What Should You Inspect During an Oil Change?

Routine oil maintenance is also an opportunity to visually inspect the engine bay and underbody.

Pay attention to:

• Oil-filter housing leakage
• Engine oil leaks
• Coolant leaks
• Turbocharger oil-line leakage
• Coolant hose condition
• Intake and charge-air connections
• Accessory belt condition
• Fluid underneath the vehicle
• Damaged electrical connectors
• Abnormal contamination in the old oil filter

A visible leak should be properly diagnosed rather than assuming that the component nearest the oil is responsible.

Common BMW B46/B48 Oil Change Mistakes

Several common mistakes are easy to avoid:

• Choosing oil based only on 0W-20
• Ignoring BMW Longlife specifications
• Assuming every B46/B48 application uses identical service components
• Ordering only by chassis code
• Reusing the old oil filter
• Reusing worn sealing components
• Incorrectly positioning the filter O-ring
• Automatically pouring all 6 liters into the engine
• Overfilling the engine
• Guessing torque specifications
• Failing to inspect for leaks
• Ordering without checking the VIN or production date

Correct vehicle identification before ordering is one of the easiest ways to prevent fitment problems.
