BMW B58 5W-30 Oil Change Guide – M240i, 340i, 440i & More

BMW's B58 3.0L turbocharged inline-six has become one of the brand's best-known modern engines. Found in models ranging from the M240i, 340i and 440i to the M340i, 540i, X3 M40i and Z4 M40i, the B58 combines strong performance with everyday usability.

Proper lubrication is an essential part of maintaining these engines. For compatible applications, the Liqui Moly Special Tec LL 5W-30 BMW B58 Oil Change Kit combines 7 liters of Liqui Moly Special Tec LL SAE 5W-30 with an OE-quality oil filter and applicable service seals in one convenient maintenance package.

Why Regular Oil Changes Matter on the BMW B58

The B58 is a turbocharged engine, meaning its lubrication system has to protect not only conventional internal engine components but also operate under the elevated thermal demands associated with turbocharging.

Fresh engine oil helps reduce friction, control wear and carry contaminants toward the oil filter.

As oil accumulates mileage and heat cycles, its condition gradually deteriorates. Regular oil and filter replacement therefore remains one of the fundamentals of preventative B58 maintenance.

Why Liqui Moly Special Tec LL 5W-30?

This service package uses Liqui Moly Special Tec LL SAE 5W-30.

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

Liqui Moly also lists Special Tec LL 5W-30 with ACEA A3/B4, API SL, MB-Approval 229.5 and VW 502 00/505 00. The manufacturer highlights high lubrication reliability, engine cleanliness, shear stability and rapid lubrication after cold starts.

This is why choosing engine oil should involve more than simply matching 5W-30 on the bottle.

For owners preparing for service, the complete Liqui Moly 5W-30 B58 oil change kit provides the primary maintenance components together.

What's Included in the B58 Oil Change Kit?

Having the oil, filter and applicable seals together simplifies preparation for routine BMW maintenance.

BMW B58 Applications

The B58 engine family appears across numerous BMW chassis and model lines.

Compatible applications include:

Always verify the year, engine, production date and VIN before ordering because B58 applications span several generations and engine revisions.

BMW 340i B58 Oil Change

The F30 BMW 340i was one of the first major BMW models to introduce the B58 to a wide enthusiast audience.

Its 3.0L turbocharged inline-six replaced the N55 used in the earlier F30 335i.

That distinction is important when purchasing maintenance components.

A customer searching simply for an "F30 oil change kit" could encounter products intended for different engines. Engine identification should therefore take priority over chassis alone.

For compatible applications, the BMW 340i Liqui Moly 5W-30 Oil Change Kit combines the oil and filtration components needed for routine service.

BMW 440i B58 Oil Change

The F32 440i Coupe, F33 440i Convertible and F36 440i Gran Coupe also use BMW's B58 engine family.

These models replaced earlier 435i variants powered by the N55.

Again, the model designation matters. A 435i and 440i may belong to the same general 4 Series generation, but they should not automatically be assumed to use identical engine-service components.

For compatible B58-powered models, the BMW 440i 5W-30 Oil Change Kit provides 7 liters of Liqui Moly Special Tec LL together with the applicable oil filter and service seals.

BMW M240i Oil Change

The F22/F23 M240i is another popular B58-powered BMW.

It should not be confused with the earlier M235i, which uses an N55 engine.

This difference is especially important when ordering filters and other engine-specific maintenance parts.

Confirm that the vehicle is genuinely a B58-powered M240i before purchasing a B58 service kit.

BMW M340i Oil Change

BMW continued development of the B58 into later generations, including the G20 M340i.

The M340i uses a newer evolution of the B58 platform, demonstrating how widely BMW has developed and deployed this engine family.

Because B58 versions can differ by model year and chassis, owners should verify compatibility using vehicle information rather than assuming that every part labeled "B58" fits every B58-powered BMW.

BMW X3 M40i & X4 M40i Oil Change

The B58 isn't limited to sedans and coupes.

BMW also uses the engine in performance-oriented SUVs such as the G01 X3 M40i and G02 X4 M40i.

The same basic maintenance principles apply: use the correct lubricant, replace the filter during the oil service, install fresh sealing components where applicable and verify the final engine-oil level.

BMW Z4 M40i B58 Oil Change

The G29 Z4 M40i is another B58-powered application.

Its engine architecture is closely related to other modern B58 applications, but model-specific compatibility should still be verified before ordering service components.

The SayParts BMW B58 Oil Change Kit is designed to make that routine maintenance process more convenient for compatible vehicles.

What Does BMW Longlife-01 Mean?

BMW Longlife-01, commonly abbreviated as BMW LL-01, is an engine-oil specification.

It is separate from SAE viscosity.

For example:

5W-30 = viscosity grade

BMW Longlife-01 = manufacturer oil specification

This distinction matters because two different oils can both carry a 5W-30 viscosity rating while meeting different manufacturer requirements.

Liqui Moly Special Tec LL 5W-30 carries BMW Longlife-01 approval, making it relevant to compatible BMW applications requiring that specification.

Turbocharged Engines and Oil Maintenance

Turbocharging places additional demands on engine lubrication.

A turbocharger operates at extremely high rotational speeds and temperatures, and engine oil plays an important role in its lubrication.

This makes proper oil condition particularly important on performance-oriented turbocharged engines such as the B58.

Fresh oil cannot repair a worn turbocharger or damaged engine component, but correct lubrication and regular servicing form an important part of preventative maintenance.

Why Replace the Oil Filter With Every Oil Change?

The engine oil and oil filter work as a system.

As oil circulates through the engine, the filter captures contaminants before the lubricant continues through the lubrication circuit.

Installing new engine oil while retaining an old filter leaves an already-used filtration element in service.

For routine maintenance, replacing the oil and filter together provides a cleaner starting point for the next service interval.

BMW B58 Oil Filter Reference

An important BMW OE filter reference associated with these applications is:

BMW OE: 11428583898

A newer/superseding reference may also appear in current parts catalogs:

BMW OE: 11425B4C845

These are manufacturer component references and should not be confused with retailer-specific kit numbers.

The Liqui Moly B58 Oil Change Kit available from SayParts combines the applicable filtration component with the engine oil needed for the service package.

How Much Oil Comes With the Kit?

The package contains:

5L + 1L + 1L = 7 liters

of Liqui Moly Special Tec LL SAE 5W-30.

However, the amount supplied in a service kit should not automatically be interpreted as the exact refill capacity for every compatible BMW.

Different B58 revisions and vehicle applications can have different service requirements.

Always follow the correct service procedure for your exact vehicle and verify the final oil level after filling.

Basic BMW B58 Oil Change Procedure

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

The old cartridge oil filter is removed and replaced along with the applicable sealing components.

After reinstalling the drain components correctly, fresh engine oil can be added according to the appropriate procedure.

Once filled, allow the lubrication system to circulate the fresh oil and inspect the filter and drain areas carefully for leaks.

Finally, verify the engine-oil level using the appropriate procedure for the vehicle.

Always follow BMW service information and correct torque specifications for your exact application.

What Should You Inspect During a B58 Oil Change?

Oil service is also a useful opportunity to inspect the engine compartment and underside of the vehicle.

Look for:

• Engine oil leaks
• Oil around the filter housing
• Coolant leakage
• Damaged hoses
• Damaged electrical connectors
• Unusual contamination in the old oil filter
• Fluid underneath the engine
• Damaged or incorrectly seated seals

Remember that the lowest visible oil spot isn't necessarily the original source of a leak. Fluid can travel across components before dripping.

N55 vs B58: Know Which Engine You Have

This is particularly important for BMW owners.

Several model transitions correspond with BMW's move from N55 to B58 power.

Examples include:

Although these vehicles may share related chassis platforms, their engines are different.

Always order engine-maintenance components according to the actual engine installed in the vehicle.

How Often Should You Change B58 Engine Oil?

Oil-service intervals depend on more than mileage alone.

Important factors include:

• Mileage
• Time since the previous service
• Short-trip frequency
• Driving style
• Operating temperature
• Climate
• Performance driving
• Track use
• Vehicle age
• Maintenance history

A B58 used primarily for gentle highway driving experiences different operating conditions from an M240i or M340i regularly driven aggressively.

Maintenance strategy should reflect actual vehicle usage.

Common BMW B58 Oil Change Mistakes

Some easily avoidable mistakes include:

• Ordering parts without verifying the B58 engine
• Confusing N55 and B58 applications
• Choosing oil based only on viscosity
• Reusing the old oil filter
• Reusing aged sealing components
• Incorrect O-ring installation
• Overfilling the engine
• Guessing torque specifications
• Failing to inspect for leaks
• Assuming every B58 application uses identical service components

Correct vehicle identification before ordering prevents many of these problems.
