Basics of BMW B58 Oil: Function & Needs
All internal combustion engines need quality engine oil to work at their best. Lubrication, protection, cooling, and cleaning are the four main things it does. Different metals, like steel, aluminum, magnesium, and sometimes titanium, interact with each other inside the engine. Friction is made when metals rub with each other, and without engine oil, it makes the surfaces hot and wear down.
Engine oil is spread out all over the engine. Aside from the oil pan where it stays, it covers the crankshaft, connecting rods, and other parts. It’s also pumped to the cylinder head to keep the valve train from wearing out. High-end engine oils work well in an engine like the B58, which generates a lot of heat and pressure. They are very good at making a strong layer of lubrication on the inside of an engine. They also keep working even when the temperature is very high or very low.
BMW B58 Oil Consumption
The BMW B58 engine typically uses 1 liter of engine oil per 1,500 miles, but the extent varies depending on driving patterns and engine health. While BMW acknowledges this as normal for certain models, overconsumption may lead to underlying problems. These problems can be worn-out piston rings or valve seals. Checking engine oil levels and following the maintenance schedule regularly is strongly recommended. It helps uphold peak engine performance and ensure long-term durability.
Types of Engine Oils
If your car has an ICE (internal combustion engine), you can get one of three main kinds of engine oil. The BMW B58 is no different. The three types are fully synthetic, synthetic blend, and conventional. To understand what kind of oil the BMW B58 needs, you must first understand these types of oils.
Full Synthetic Oil
Full synthetic oil is renowned for its superior quality and durability. It stands out as the best option for BMW B58 engines. It ensures exceptional performance and top-notch protection. Full synthetic engine oil features a uniform molecular structure and improved lubricating properties. It delivers unparalleled protection for high-performance engines.
Pros
- Offers superior lubrication and protection, especially at high temperatures and under extreme conditions.
- Longer oil change intervals compared to conventional and synthetic blend oils.
- Provides better fuel efficiency and engine cleanliness.
Cons
- Generally more expensive than conventional and synthetic blend oils.
Synthetic Blend Oil
The unique mix of conventional and synthetic base oils makes synthetic blend engine oils. These engine oils are a good mix of performance and value for money. They protect engines better and make them run better than conventional oil. Despite this, they stay less expensive than the full synthetic choices.
Pros
- Offers some benefits of synthetic oils at a lower cost.
- Provides better protection against engine wear and breakdown compared to conventional oil.
Cons
- It’s not as robust as full synthetic oils.
- More frequent oil changes will be required than full synthetics.
Mineral Oil
Mineral oil, also known as conventional oil, comes from crude oil. However, it’s not widely used in modern cars. This is because it doesn’t offer the same level of performance and protection as synthetic oils. Mineral oil isn’t as stable in hot temperatures. Mineral oils are more susceptible to degrade under high temperatures. It effectively means that it breaks down faster and can cause more wear and tear on your engine over the long term.
Pros
- Generally cheaper than synthetic options.
- Suitable for older engines with looser tolerances.
Cons
- Prone to break down at high temperatures.
- Typically, it requires more frequent oil changes.
Explained: BMW B58 Oil Terminologies
Certain standards are used to judge the quality of the engine oil. These factors describe certain qualities of oils and how well they work in different situations. You need to know these things to choose the best BMW B58 engine oil for your expensive BMW. It keeps engines in good shape and makes sure they work well.
Viscosity
Viscosity is the measure of an oil’s resistance to flow. Viscosity is represented by a combination of numbers and letters, such as 0W-20 or 5W-30. The number preceding the ‘W’ (which stands for “winter”) indicates the oil’s viscosity at low temperatures, while the number following the ‘W’ represents its viscosity at high temperatures.
- Lower numbers indicate thinner, less viscous oils that flow more easily at cold temperatures.
- Higher numbers indicate thicker, more viscous oils that maintain their viscosity better at high temperatures.
When selecting the BMW B58 oil, it is important to consider the viscosity grade, which should specify your BMW’s needs.
BMW LL (Longlife) Specifications
BMW LL (Longlife) specifications are standards that BMW has established for motor oils used in its vehicles. These specifications ensure that the engine oil has BMW’s stamp of approval and meets the performance, durability, and compatibility requirements with its engines.
There are several BMW LL specifications, each denoted by a number. For example:
BMW LL-17FE+ — This specification is BMW’s latest standard and its first recommendation. It indicates that the engine oil meets the most up-to-date requirements for BMW engines, including the B58.
The “FE+” in LL-17FE+ indicates that the oil meets the latest fuel economy standards. Oils meeting this specification are formulated to provide excellent engine protection, fuel efficiency, and compatibility with emission control systems. BMW recommends engine oil with LL17FE+ 0W-20 rating for B58 engines.
BMW LL-04—This specification is for long-life oils designed for diesel engines, but it has been approved for use on gasoline engines. It is usually considered an alternative to the LL-17FE+. Oils meeting LL-04 are formulated to meet the specific requirements of BMW gasoline engines, including the B58.
They provide excellent engine protection and compatibility with emission control systems. LL-04 oils have low ash content to prevent harm to exhaust gas recirculation (EGR) systems and particulate filters. BMW specifies LL04 0W-30 & 5W-30 rated engine oils as an alternative for BMW B58 engines.
BMW LL-12 — This is another alternative specification for long-life oils. It is designed for BMW diesel engines with exhaust gas recirculation (EGR) systems and particulate filters. Like LL-04, LL-12 oils have low ash content. They prevent harm to emission control systems and provide extended oil change intervals. LL12 0W-30-rated engine oils can also be used on BMW B58 engines.
These specifications outline various performance characteristics, including viscosity, volatility, shear stability, and compatibility with emissions control systems. BMW recommends using motor oils that meet or exceed the specific LL specifications recommended for your vehicle.

Drain the Oil — Allow the old oil to drain completely into the drain pan. This may take a few minutes. Once you see no continuous drip of oil, reinstall the drain plug with a new crush washer and tighten it to 19 ft. lb (25 Nm).
Remove the Oil Filter — When removing the oil filter during an oil change on a BMW B58 engine, start by locating the oil filter housing. It is accessed on top of the engine, but you must first remove the engine cover and the DME cover. Visit our article to learn more about oil filters, the reasons why the oil filter gets damaged during removal, and how to avoid it.
Replace the Oil Filter — Once the oil filter cap is removed, carefully remove the old oil filter from the oil filter cap. Wipe down the area around the housing to ensure it’s clean. Install the new oil filter into the housing, ensuring it’s properly seated.
Tighten the Oil Filter Cap — Use the 1 ¼ socket to screw in the oil filter cap and tighten it to 19 ft. lb (25 Nm).
How much oil does a B58 take?
The BMW B58 engine, found in various models, typically requires approximately 6.9 qt to 7.4 qt (around 6.5 to 7 liters) of engine oil for a complete oil change. However, it’s always best to refer to your vehicle’s owner’s manual to confirm the exact oil capacity for your particular model. It can vary slightly depending on factors such as engine configuration and year of manufacture.
Add new oil — Locate the oil filler cap on the top of the engine and remove it. Then, carefully use a funnel to add the recommended amount of new engine oil. A best practice during an oil change is to fill the engine oil to a level slightly below its fill point. For this example, if the fill point for the BMW B58 engine is 6.9 quarts, initially filling it to around 6.4 quarts is advisable. This allows for proper oil circulation and prevents overfilling.
Check for Leaks and Clean Up — Start the engine and let it run for a few minutes. Check underneath the vehicle for leaks around the oil drain plug and oil filter housing. Turn off the engine and check the oil level again. Top up if necessary. Clean up spilled engine oil, dispose of the old oil, and filter properly.
Reset the Maintenance Indicator — If your BMW has a maintenance reminder system, reset it to indicate that the oil change has been performed.
How do I reset the oil change indicator in my BMW B58?
The process for resetting the oil change indicator may vary depending on the specific BMW model and year. Generally, you can reset it through the vehicle’s onboard computer system using the dashboard controls. Refer to the owner’s manual for precise instructions.
Maintenance Tips
Maintaining the health of your BMW B58 engine is crucial for ensuring optimal performance, reliability, and longevity. Here are some tips to help you keep your B58 engine in top condition:
Regular Inspections
Routinely inspect the engine and its components for signs of leaks, wear, or damage. If you notice unusual noises, vibrations, or warning lights on the instrument cluster, they could indicate underlying issues that need attention. Address any problems quickly.
Follow the Manufacturer’s Maintenance Schedule
Follow BMW’s recommended maintenance schedule, which is included in your warranty and maintenance booklet. This schedule includes regular oil changes, filter replacements, spark plug replacements, and other scheduled maintenance tasks.
Use High-Quality Engine Oil
Choose a high-quality synthetic engine oil that meets BMW’s specifications for the BMW B58 engine. Use the recommended viscosity grade and look for oils with BMW Longlife approval. Regularly check the oil level, top up as needed, and never exceed the recommended oil change intervals.
What is the best oil for a tuned B58 engine?
Since a tuned engine typically operates under higher stress and temperatures, a synthetic oil with a higher viscosity index and better thermal stability would be ideal. Look for oils that meet BMW’s LL-17FE+ (LL17FE+ 0W-20), LL-04 (LL04 0W-30 & 5W-30), or LL-12 (LL12 0W-30) specifications. They are formulated to meet the specific requirements of BMW engines, including the B58. Tuning places additional stress on the engine, which causes the oil to degrade faster. Usually, an oil change every 5,000 miles can extend the engine’s health.
