BMW B58 5W-40 Oil Change Guide – 340i, 440i & xDrive

BMW's B58 3.0-liter turbocharged inline-six is found in some of the most desirable modern BMW models, including the F30 340i, F32 440i, F33 440i Convertible, F34 340i Gran Turismo and F36 440i Gran Coupe.

Whether your BMW is rear-wheel drive or xDrive, regular engine oil and filter maintenance is one of the fundamentals of keeping the B58 properly serviced.

For compatible applications, the Liqui Moly Leichtlauf High Tech 5W-40 BMW B58 Oil Change Kit combines 7 liters of Liqui Moly Leichtlauf High Tech SAE 5W-40 with a Genuine BMW / UFI oil filter and applicable oil-service sealing components.

Why Oil Maintenance Matters on the BMW B58

The B58 is a turbocharged engine, meaning its lubrication system has to protect not only internal engine components but also the turbocharger.

Engine oil performs several critical jobs:

• Reduces friction between moving components
• Helps protect against engine wear
• Lubricates the turbocharger
• Carries contaminants toward the oil filter
• Helps control deposits
• Contributes to engine temperature management
• Provides lubrication immediately after startup

As engine oil accumulates mileage, time and repeated heat cycles, its ability to perform these tasks gradually deteriorates.

Replacing the engine oil and filter together provides the lubrication system with fresh oil and a new filtration element.

Why Liqui Moly Leichtlauf High Tech 5W-40?

Liqui Moly Leichtlauf High Tech SAE 5W-40 is a high-performance engine oil designed for demanding gasoline and diesel applications.

For compatible BMW B58 applications, one of its most important characteristics is its official BMW Longlife-01 approval.

Liqui Moly currently lists the following approvals for Leichtlauf High Tech 5W-40:

ACEA A3/B4
API SP
BMW Longlife-01
MB-Approval 229.5
Porsche A40
VW 502 00 / 505 00

Liqui Moly also describes the oil as tested for use with turbochargers and catalytic converters.

For owners preparing for maintenance, the BMW B58 Liqui Moly 5W-40 Oil Change Kit puts the primary service components together in one package.

What's Included in the B58 Oil Change Kit?

Oil Filter Brand: Genuine BMW / UFI

This kit does not use an unidentified generic filter.

The included cartridge-style filter is a Genuine BMW / UFI oil filter.

BMW OE Filter Reference: 11428583898

This gives owners a clear OEM reference when checking compatibility before ordering.

BMW B58 Vehicle Fitment

The kit is intended for compatible B58-powered applications including:

Always verify your BMW's year, model, engine, production date and VIN before ordering.

BMW 340i Oil Change

The F30 BMW 340i introduced the B58 engine to the 3 Series lineup, replacing the N55-powered 335i as BMW updated the model range.

Its turbocharged 3.0-liter inline-six delivers strong performance while retaining the smooth character associated with BMW's six-cylinder engines.

For compatible vehicles, the BMW 340i Liqui Moly 5W-40 Oil Change Kit provides 7 liters of Leichtlauf High Tech 5W-40 together with a Genuine BMW / UFI oil filter.

BMW 340i xDrive Oil Change

The 340i xDrive combines the B58 with BMW's all-wheel-drive system.

Although the drivetrain layout differs from a rear-wheel-drive 340i, the basic engine-oil service still involves selecting the correct oil specification, replacing the cartridge filter, installing fresh applicable sealing components and verifying the final oil level.

Owners should still verify exact vehicle fitment before ordering, particularly when dealing with production-date changes.

BMW 440i Oil Change

The 440i brought the B58 engine to BMW's 4 Series family.

Depending on configuration, the B58 can be found in the:

440i Coupe
440i xDrive Coupe
440i Convertible
440i xDrive Convertible
440i Gran Coupe
440i xDrive Gran Coupe

For compatible applications, the BMW 440i B58 5W-40 Oil Change Kit combines Liqui Moly engine oil with the corresponding Genuine BMW / UFI filter.

What Does BMW Longlife-01 Mean?

When choosing engine oil, viscosity and manufacturer approval should not be treated as the same thing.

5W-40 = SAE viscosity grade

BMW Longlife-01 = BMW engine-oil specification

This distinction is important because two engine oils can both carry a 5W-40 viscosity rating while meeting completely different manufacturer requirements.

Liqui Moly officially lists BMW Longlife-01 among the approvals for Leichtlauf High Tech 5W-40.

Therefore, oil selection should involve checking the required manufacturer specification for the particular BMW application rather than relying only on the viscosity printed on the bottle.

5W-40 and the BMW B58

SAE 5W-40 is a multigrade viscosity.

The first part of the designation relates to the oil's low-temperature viscosity characteristics, while the second describes its viscosity classification at operating temperature.

But viscosity alone does not establish whether a particular oil is appropriate for a specific engine.

For compatible applications covered by this package, the combination of SAE 5W-40 and BMW Longlife-01 approval is the relevant distinction.

Always confirm the oil requirements for your exact model, year and market before servicing the vehicle.

Why Turbocharged Engines Need Quality Lubrication

A turbocharger operates at extremely high rotational speeds and depends on engine oil for lubrication.

This makes oil condition especially important in a turbocharged engine such as the B58.

Correct lubrication contributes to:

• Turbocharger bearing protection
• Reduced internal friction
• Engine cleanliness
• Protection during high-temperature operation
• Reliable cold-start lubrication
• Protection of internal engine components

Regular oil maintenance cannot prevent every mechanical failure, but it is an important part of maintaining a turbocharged engine.

Why Replace the Oil Filter During Every Oil Change?

Fresh engine oil should be paired with a fresh filter.

During operation, contaminants become trapped within the filter media. Reusing an old filter means fresh engine oil immediately begins circulating through a filtration element that has already accumulated service time.

For this reason, replacing the oil filter at the same time as the engine oil is standard maintenance practice.

The complete Liqui Moly B58 oil service kit includes the appropriate filter for compatible applications.

Genuine BMW / UFI Oil Filter

The filter supplied with this package is identified as:

Filter Brand: Genuine BMW / UFI
Filter Type: Cartridge Oil Filter
BMW OE Reference: 11428583898

The BMW number is provided as an OEM cross-reference to help identify the component.

It should not be confused with a retailer SKU or the SayParts inventory number.

How Much Oil Comes With the Kit?

The package supplies:

5 liters + 1 liter + 1 liter = 7 liters

of Liqui Moly Leichtlauf High Tech SAE 5W-40.

An important point is that the quantity supplied with an oil-change kit should not automatically be interpreted as the exact refill amount that should be poured into the engine.

Always follow the appropriate BMW service procedure for your exact B58 application and verify the final engine-oil level after servicing.

Basic BMW B58 Oil Change Procedure

A typical B58 oil service starts by safely preparing the vehicle and draining the used engine oil.

The old cartridge oil filter should then be removed and replaced with the new Genuine BMW / UFI filter.

Replace the applicable O-ring and sealing components during the service. Apply a small amount of clean engine oil to the new filter O-ring before installation and ensure it is seated in the correct position.

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

Start the engine and allow the lubrication system to circulate the fresh oil.

Then:

• Inspect the oil-filter housing for leakage
• Inspect the drain area
• Verify that no warning messages are present
• Check the engine-oil level
• Correct the level if necessary
• Recheck the engine for leaks

Always follow the correct BMW service procedures and torque specifications for your particular vehicle.

What Should You Inspect During a B58 Oil Change?

An oil service also provides a useful opportunity to inspect other engine components.

Check for:

• Engine oil leaks
• Oil-filter housing leakage
• Coolant leakage
• Damaged coolant hoses
• Turbocharger oil-line leakage
• Damaged intake or charge-air connections
• Belt condition
• Electrical connector damage
• Fluid underneath the vehicle
• Abnormal contamination in the used filter

Finding developing problems during routine maintenance can help prevent them from becoming more expensive repairs.

B58 vs N55 – Don't Order by Chassis Alone

BMW model generations can contain different engines depending on year and model.

For example, an F30 chassis designation alone is not enough to determine the correct oil-service components.

The 335i is commonly associated with the N55 engine, while the later 340i uses the B58.

Similarly, the transition from the 435i to the 440i corresponds with significant powertrain changes.

This is why SayParts recommends checking:

Model → Year → Engine → Production Date → VIN

rather than ordering maintenance components based only on chassis generation.

340i vs 440i Oil Service

The 340i and 440i use the B58 engine in compatible configurations, despite belonging to different BMW model families.

The 340i belongs to the 3 Series, while the 440i belongs to the 4 Series.

Because compatible versions share the B58 powerplant, many engine-maintenance components can overlap.

However, never assume every component is interchangeable simply because two BMWs use the same basic engine family.

For this specific oil service, check compatibility with the Liqui Moly 5W-40 BMW 340i and 440i Oil Change Kit before ordering.

Common BMW B58 Oil Change Mistakes

Common avoidable mistakes include:

• Selecting engine oil based only on viscosity
• Ignoring BMW oil specifications
• Ordering parts based only on the chassis
• Confusing N55 and B58 applications
• Reusing an old oil filter
• Reusing aged sealing components
• Installing the filter O-ring incorrectly
• Automatically pouring the entire kit quantity into the engine
• Overfilling the engine
• Guessing torque specifications
• Failing to check for leaks after servicing
• Ordering without confirming exact vehicle fitment

Correct vehicle identification before purchasing parts eliminates many of these problems.
