BMW 328d & X3 xDrive28d 5W-30 Diesel Oil Change Guide – N47 Engine

BMW's N47 2.0L turbo-diesel engine powers several popular U.S.-market diesel models, including the F30 328d, F31 328d xDrive Wagon and F25 X3 xDrive28d. These engines combine strong low-end torque and fuel efficiency with modern emissions equipment, making correct engine-oil maintenance particularly important.

For compatible applications, the Liqui Moly Top Tec 4600 5W-30 BMW Diesel Oil Change Kit combines 6 liters of Liqui Moly Top Tec 4600 SAE 5W-30 with a MAHLE OX 404D oil filter and applicable service sealing components.

Why Oil Maintenance Matters on the BMW N47 Diesel

A modern turbo-diesel engine places substantial demands on its lubrication system.

Engine oil must lubricate internal components, protect the turbocharger, help control deposits and operate alongside emissions systems such as the diesel particulate filter (DPF).

For that reason, choosing oil for an N47-powered BMW involves more than simply looking for a bottle marked 5W-30.

The required oil specification and compatibility with diesel exhaust after-treatment systems are important considerations.

Why Liqui Moly Top Tec 4600 5W-30?

Liqui Moly Top Tec 4600 SAE 5W-30 is a modern low-SAPS engine oil carrying BMW Longlife-04 approval. Liqui Moly also lists ACEA C2/C3 and MB-Approvals 229.31, 229.51 and 229.52 among its current approvals and specifications.

The low-SAPS formulation is particularly relevant for compatible diesel engines equipped with particulate filters.

Liqui Moly highlights characteristics including:

• Excellent wear protection
• High lubrication reliability
• High shear stability
• Excellent engine cleanliness
• Rapid lubrication after cold starts
• Strong aging stability
• Turbocharger compatibility
• Diesel particulate filter compatibility

For owners preparing for maintenance, the complete BMW N47 diesel oil change kit provides the primary oil-service components together.

What's Included in the Kit?

Oil Filter Brand: MAHLE

Unlike a generic maintenance package, this kit uses a MAHLE oil filter.

MAHLE Filter Part Number: OX 404D
BMW OE Reference: 11428507683

This gives BMW owners a clear filter-manufacturer reference when verifying their service components.

BMW N47 Vehicle Fitment

This oil service package is intended for compatible N47-powered applications including:

Always verify the model year, engine, production date and VIN before ordering maintenance parts.

BMW 328d Oil Change

The F30 BMW 328d brought BMW's four-cylinder turbo-diesel technology to the U.S. 3 Series market.

Its combination of diesel torque and fuel economy makes it very different mechanically from gasoline-powered F30 models such as the 328i.

That difference matters when selecting engine oil.

For compatible N47 applications, the BMW 328d Liqui Moly Top Tec 4600 Oil Change Kit provides BMW Longlife-04 approved 5W-30 oil together with a MAHLE oil filter.

BMW 328d xDrive Oil Change

The 328d xDrive combines the N47 diesel engine with BMW's all-wheel-drive system.

Although xDrive changes the vehicle's drivetrain layout, engine-oil maintenance still centers around using the appropriate lubricant, replacing the oil filter and correctly installing new sealing components.

Do not confuse the 328d xDrive with gasoline-powered 328i xDrive models when purchasing engine-maintenance components.

BMW 328d xDrive Wagon Oil Change

The F31 328d xDrive Sports Wagon has become a particularly interesting BMW for enthusiasts because it combines wagon practicality, diesel efficiency and all-wheel drive.

Like the sedan, it uses the N47 diesel engine in compatible U.S.-market applications.

Owners preparing for routine maintenance can use the Liqui Moly 5W-30 BMW 328d diesel oil change kit to obtain the oil and MAHLE filtration components together.

BMW X3 xDrive28d Oil Change

The F25 BMW X3 xDrive28d also uses BMW's 2.0L turbo-diesel engine in compatible applications.

Because the engine is equipped with modern diesel emissions equipment, using an oil carrying the appropriate manufacturer approval is especially important.

The BMW X3 xDrive28d Top Tec 4600 5W-30 Oil Change Kit provides the same 6-liter Liqui Moly and MAHLE filter combination for compatible applications.

What Is BMW Longlife-04?

BMW Longlife-04, commonly abbreviated as BMW LL-04, is an engine-oil specification.

It should not be confused with viscosity.

5W-30 = SAE viscosity grade

BMW Longlife-04 = BMW oil specification

Two different engine oils can both carry a 5W-30 viscosity grade while meeting very different manufacturer specifications.

Liqui Moly officially lists BMW Longlife-04 among the approvals for Top Tec 4600 SAE 5W-30.

For a modern BMW diesel, checking the required specification is therefore more useful than selecting oil based solely on viscosity.

What Does Low-SAPS Mean?

Low-SAPS oils are formulated with controlled levels of sulfated ash, phosphorus and sulfur.

This is particularly relevant to vehicles equipped with modern exhaust after-treatment systems.

BMW diesel engines such as the N47 use emissions-control equipment that can include a diesel particulate filter.

Using an appropriate low-SAPS lubricant helps maintain compatibility with these systems.

This is one of the key reasons Top Tec 4600 differs from the Special Tec LL oils used in many of our gasoline BMW oil-change kits.

Why DPF Compatibility Matters

A diesel particulate filter captures particulate matter from the engine's exhaust.

Unlike ordinary carbon soot that can be addressed during regeneration, certain inorganic residues can accumulate over time.

For DPF-equipped applications, using an engine oil designed around the appropriate emissions-system requirements is therefore important.

Liqui Moly specifically positions Top Tec 4600 for compatible vehicles with diesel particulate filters.

Turbo Diesel Engines and Engine Oil

The N47's turbocharger also depends on engine oil for lubrication.

Turbochargers operate at high rotational speeds and significant temperatures, placing additional demands on the lubricant.

Proper oil maintenance supports:

• Turbocharger lubrication
• Internal engine wear protection
• Engine cleanliness
• Lubrication during cold starts
• Stable performance at operating temperature

Fresh engine oil cannot repair a mechanically damaged turbocharger, but maintaining the correct lubricant is an important part of preventative maintenance.

Why Use a MAHLE Oil Filter?

The filter is just as important as the engine oil during routine service.

This kit uses a:

MAHLE OX 404D Oil Filter

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

The filter captures contaminants circulating through the lubrication system while maintaining the required oil flow.

For this reason, replacing the filter whenever the engine oil is changed provides a fresh filtration element for the new lubricant.

BMW Oil Filter Reference

The relevant component references for this package are:

Oil Filter Brand: MAHLE
MAHLE Part Number: OX 404D
BMW OE Reference: 11428507683

The BMW number is an OEM cross-reference, while OX 404D identifies the MAHLE filtration component.

The SayParts BMW N47 Diesel Oil Change Kit combines this MAHLE filter with Liqui Moly Top Tec 4600.

How Much Oil Comes With the Kit?

The kit contains:

5L + 1L = 6 liters

of Liqui Moly Top Tec 4600 SAE 5W-30.

The amount supplied with an oil-change package should not automatically be interpreted as the exact amount that should be poured into every compatible vehicle.

Actual refill requirements can vary according to the specific engine and application.

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

Basic BMW N47 Oil Change Procedure

A typical N47 oil service begins by safely preparing the vehicle and allowing the used engine oil to drain.

The existing cartridge oil filter is removed from its housing and replaced with the new MAHLE OX 404D filter.

Applicable O-rings and sealing components should also be replaced.

Lubricate the new O-ring with clean engine oil and ensure that it is correctly positioned before reinstalling the filter housing.

After reinstalling the drain components, add the appropriate quantity of fresh engine oil.

Start the engine, allow the lubrication system to circulate the fresh oil and inspect the filter housing and drain area carefully for leaks.

Finally, verify the engine-oil level according to the correct BMW procedure.

Always follow the appropriate BMW service information and torque specifications for your specific vehicle.

What Should You Inspect During a BMW Diesel Oil Change?

Oil service is a good opportunity to inspect other areas of an aging diesel BMW.

Look for:

• Engine oil leakage
• Oil-filter housing leakage
• Coolant leakage
• Turbocharger oil-line leakage
• Damaged intake or boost hoses
• Abnormal contamination in the old filter
• Damaged sealing components
• Fluid underneath the engine
• Visible wiring or connector damage

If a leak is discovered, identify its actual source before replacing components. Oil can travel across engine surfaces before reaching the lowest visible point.

Diesel vs Gasoline BMW Oil Change Kits

Do not assume that an oil kit designed for a gasoline BMW is appropriate simply because both products use 5W-30.

For example, Liqui Moly Special Tec LL 5W-30 and Liqui Moly Top Tec 4600 5W-30 share a viscosity grade but carry different approvals and are designed around different application requirements.

For this N47 diesel package, the key combination is:

Liqui Moly Top Tec 4600 5W-30

BMW Longlife-04

Low-SAPS formulation

MAHLE OX 404D oil filter

This illustrates why viscosity alone should never be the only selection criterion.

Common BMW N47 Oil Change Mistakes

Avoidable mistakes include:

• Choosing engine oil based only on 5W-30 viscosity
• Ignoring BMW Longlife approval requirements
• Using an inappropriate oil for a DPF-equipped diesel
• Confusing the 328d with the gasoline 328i
• Reusing the old oil filter
• Reusing aged filter seals
• Incorrectly installing the filter O-ring
• Overfilling the engine
• Guessing torque specifications
• Failing to check for leaks after service
• Ordering components without confirming the VIN or engine

Correct vehicle identification and proper service preparation prevent many of these problems.
