BMW X1, X2, 228i & M235i 0W-20 Oil Change Guide – Liqui Moly Top Tec 6600

Modern BMW turbocharged engines require more than simply choosing an oil with the correct viscosity. The manufacturer approval, oil-filter specification and exact vehicle application all matter when performing routine maintenance.

For compatible BMW X1, X2, 228i xDrive Gran Coupe and M235i xDrive Gran Coupe applications, the Liqui Moly Top Tec 6600 0W-20 oil service package combines 6 liters of premium synthetic engine oil with a MANN-FILTER oil filter corresponding to BMW OE reference 11428593186.

For owners preparing for their next service, the Liqui Moly Top Tec 6600 0W-20 BMW X1 X2 228i M235i Oil Change Kit provides the primary oil-service components in one convenient package.

Why Regular Oil Changes Matter on Modern BMW Turbo Engines

Modern BMW 2.0-liter turbocharged engines operate under demanding conditions.

Engine oil is responsible for lubricating internal components while also protecting the turbocharger, controlling deposits and maintaining reliable lubrication across a wide range of operating temperatures.

Fresh, specification-correct engine oil helps support:

• Turbocharger lubrication
• Internal engine wear protection
• Cold-start lubrication
• Engine cleanliness
• Stable lubrication under high temperatures
• Reduced internal friction
• Protection during high-load operation
• Efficient engine operation

The oil filter is equally important because it captures contaminants as oil circulates through the lubrication system.

For this reason, replacing the engine oil and oil filter together should be considered standard maintenance practice.

Why Liqui Moly Top Tec 6600 0W-20?

Liqui Moly Top Tec 6600 SAE 0W-20 is a modern low-friction engine oil developed for vehicles requiring current low-viscosity lubricant specifications.

One of the most important characteristics for compatible BMW applications is:

BMW Longlife-17 FE+

This is an official BMW oil specification and should not be confused with the SAE viscosity printed on the bottle.

Liqui Moly currently lists specifications and approvals including:

BMW Longlife-17 FE+
ACEA C5 / C6
API SQ
ILSAC GF-7A
MB-Approval 229.71 / 229.72

Liqui Moly also describes Top Tec 6600 as providing excellent wear protection, engine cleanliness, lubrication reliability and high shear stability, while being tested for turbochargers and catalytic converters.

For compatible vehicles, the BMW Liqui Moly Top Tec 6600 0W-20 Oil Change Kit combines this oil with the appropriate MANN-FILTER filtration component.

What's Included in the Oil Change Kit?

Oil Filter Information

Brand: MANN-FILTER
BMW OE Reference: 11428593186
Type: Cartridge Oil Filter

This is an important distinction because BMW uses different oil-filter configurations across related engine families and vehicle platforms.

BMW X1 Oil Change

The BMW X1 combines a compact crossover platform with BMW's turbocharged four-cylinder engine technology.

Compatible applications can include:

BMW X1 sDrive28i
BMW X1 xDrive28i

Regular oil maintenance is particularly important for a turbocharged engine because the engine oil also contributes to turbocharger lubrication.

For compatible vehicles, the BMW X1 Liqui Moly Top Tec 6600 0W-20 Oil Change Kit provides 6 liters of oil together with a MANN-FILTER oil filter.

Always confirm exact year, engine and production date before ordering.

BMW X2 Oil Change

The BMW X2 shares many mechanical concepts with the X1 but is offered with its own model and performance configurations.

Compatible applications can include:

BMW X2 sDrive28i
BMW X2 xDrive28i
BMW X2 M35i

Even when two BMW models share a related engine architecture, oil-filter fitment should never be assumed solely from engine displacement.

The BMW OE reference 11428593186 is therefore an important identifier when confirming the correct filter.

For compatible applications, the BMW X2 0W-20 Oil Change Kit with MANN-FILTER provides the primary components required for routine oil service.

BMW X2 M35i Oil Change

The X2 M35i is the performance-oriented member of the X2 family.

Its turbocharged engine places particular importance on reliable lubrication under changing engine speeds, temperatures and loads.

Using the appropriate oil specification is therefore more meaningful than simply purchasing any oil labeled 0W-20.

Liqui Moly Top Tec 6600 carries BMW Longlife-17 FE+ approval, making the manufacturer specification immediately identifiable when checking compatibility.

BMW 228i xDrive Gran Coupe Oil Change

The BMW 228i xDrive Gran Coupe uses BMW's compact transverse-engine architecture rather than the traditional longitudinal layout found in many other BMW models.

This distinction matters when ordering maintenance parts.

A BMW 228i should not automatically be assumed to use the same oil filter as another BMW simply because both vehicles have turbocharged 2.0-liter engines.

For compatible vehicles, the BMW 228i xDrive Gran Coupe Liqui Moly 0W-20 Oil Change Kit combines Top Tec 6600 with the appropriate MANN-FILTER oil filter.

BMW M235i xDrive Gran Coupe Oil Change

The BMW M235i xDrive Gran Coupe offers a higher-performance version of BMW's compact turbocharged drivetrain.

Oil quality and correct specification remain fundamental regardless of performance level.

Engine oil must provide lubrication for:

• Internal engine bearings
• Camshaft and valvetrain components
• Timing components
• Pistons and cylinder surfaces
• Turbocharger bearings
• Other oil-fed internal components

For compatible M235i xDrive Gran Coupe applications, the BMW M235i Liqui Moly Top Tec 6600 Oil Change Kit provides both the oil and MANN-FILTER component required for the service package.

BMW Longlife-17 FE+ Explained

One of the most common mistakes when shopping for engine oil is focusing only on viscosity.

Consider these two terms:

0W-20

This describes the oil's SAE viscosity grade.

BMW Longlife-17 FE+

This identifies a BMW engine-oil specification.

They do not mean the same thing.

Two different bottles can both say 0W-20, while only one may carry the BMW specification required for a particular application.

Therefore:

0W-20 ≠ automatically BMW LL-17 FE+

Liqui Moly Top Tec 6600 specifically carries BMW Longlife-17 FE+ approval.

This is one of the main reasons checking manufacturer approval is important when selecting engine oil.

What Does 0W-20 Mean?

The 0W-20 designation describes the lubricant's SAE viscosity characteristics.

The 0W portion relates to low-temperature viscosity behavior.

The 20 portion describes its viscosity grade at operating temperature.

Modern engines can be engineered around lower-viscosity oils to help reduce internal friction while maintaining the lubrication performance required by the manufacturer.

However, viscosity alone does not determine vehicle compatibility.

Always verify the required manufacturer specification as well.

BMW LL-17 FE+ vs LL-01

BMW owners may encounter several different Longlife specifications when shopping for oil.

Two common examples are:

BMW Longlife-01 (LL-01)

and

BMW Longlife-17 FE+ (LL-17 FE+)

They should not be treated as interchangeable simply because both are BMW specifications.

For example, some of the older BMW oil-service applications may use products such as Liqui Moly Leichtlauf High Tech 5W-40 carrying BMW LL-01 approval.

The kit covered in this guide instead uses:

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

Always follow the specification appropriate for the exact vehicle.

Why Turbocharged Engines Depend on Engine Oil

Turbochargers operate at extremely high rotational speeds.

The turbocharger relies on engine oil for lubrication, meaning oil quality and condition directly affect one of the most demanding lubrication environments in the vehicle.

Proper oil maintenance helps provide:

• Turbocharger bearing lubrication
• Heat management
• Wear protection
• Deposit control
• Reliable lubrication during cold starts
• Protection during high-load driving

Oil changes cannot prevent every mechanical problem, but correct lubrication is one of the fundamentals of turbocharged-engine maintenance.

Why Replace the Oil Filter With Every Oil Change?

Fresh oil should be paired with a fresh oil filter.

As the engine operates, the filter captures contaminants circulating through the lubrication system.

Reusing the existing filter means fresh oil immediately begins circulating through a filtration element that has already accumulated service time and contaminants.

This kit therefore includes a new:

MANN-FILTER Oil Filter

with BMW OE reference:

11428593186

For compatible applications, the complete BMW X1 X2 228i M235i oil service kit supplies both the engine oil and filtration component together.

MANN-FILTER vs Generic Oil Filters

An oil filter may appear to be a relatively simple component, but its design affects filtration performance, oil flow and sealing.

This package uses a MANN-FILTER cartridge filter, rather than an unidentified generic filtration component.

The relevant identification is:

Filter Brand: MANN-FILTER
BMW OE Reference: 11428593186

This information also makes it easier for customers to verify the component before installation.

Understanding the Part Numbers

Different numbers associated with the package have different purposes.

BMW OE Reference

11428593186

This identifies the corresponding BMW oil-filter application/reference.

SayParts Kit SKU

SP-BMW-LM6600-0W20-6L-MANN-93186

This identifies the complete SayParts oil-change package.

The BMW OE reference and SayParts SKU should not be treated as the same number.

How Much Oil Comes With the Kit?

The package contains:

1 × 5L Liqui Moly Top Tec 6600

plus

1 × 1L Liqui Moly Top Tec 6600

for a total of:

6 Liters

An important distinction is that the quantity supplied with an oil-change kit does not automatically equal the exact refill capacity of every compatible engine.

Do not simply pour all six liters into the engine without checking the appropriate service information.

Follow the correct BMW procedure and verify the final oil level after servicing.

Basic BMW Oil Change Procedure

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

The existing cartridge oil filter is then removed.

Install the new MANN-FILTER oil filter and replace the applicable O-ring and sealing components.

Before installation, lightly lubricate the new filter O-ring with clean engine oil and make sure it is positioned correctly.

After reinstalling the required drain components, add the appropriate quantity of fresh Liqui Moly Top Tec 6600.

After filling:

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

Always use the correct BMW service procedure and torque specifications for your exact model.

What Else Should You Inspect During an Oil Change?

Routine maintenance provides a useful opportunity to inspect other areas of the vehicle.

Look for:

• Engine oil leaks
• Oil-filter housing leakage
• Coolant leakage
• Damaged coolant hoses
• Turbocharger oil-line leakage
• Damaged intake connections
• Accessory belt wear
• Fluid underneath the engine
• Damaged wiring or connectors
• Abnormal contamination in the old filter

Finding a developing problem during routine maintenance can help prevent a relatively small issue from becoming a more expensive repair.

Don't Order BMW Oil Filters by Engine Size Alone

This is particularly important with modern BMWs.

Two vehicles may both use:

2.0-liter engines

and both may require:

0W-20 engine oil

while still using different oil filters.

We already have another Top Tec 6600 BMW kit associated with BMW OE filter reference:

11428575211

This package uses:

11428593186

That difference is important.

Do not assume that two BMW oil-change kits are interchangeable simply because they both contain Liqui Moly Top Tec 6600 0W-20.

Always verify:

Year → Model → Engine → Production Date → VIN → OE Filter Reference

Common BMW Oil Change Mistakes

Avoid these common mistakes:

• Selecting engine oil based only on viscosity
• Ignoring BMW Longlife specifications
• Assuming all BMW 2.0L turbo engines use the same filter
• Ordering by engine displacement alone
• Ordering by model name without checking the year
• Confusing different BMW OE filter numbers
• Reusing the existing 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 after service
• Ordering without checking VIN or production date
