【Explained】What Type of Oil Does a BMW 328i Take? (The Complete Guide by Model Year)

BMW 328i requires full synthetic motor oil with specific BMW Longlife approval codes that vary by generation: E90 models (2007-2011) with N52 engines need 5W-30 or 0W-30 meeting BMW LL-01 approval with 6.9 quarts capacity, while F30 models (2012-2016) with N20/N26 turbocharged engines can use lighter 0W-20 or 5W-30 meeting LL-01, LL-14 FE+, or LL-17 FE+ specifications with 5.3 quarts capacity. The BMW Longlife approval code stamped on the oil bottle is more critical than brand choice, as it ensures proper additive packages and performance standards for your specific engine.

BMW 328i Oil Requirements by Generation

The BMW 328i spans two distinct generations with fundamentally different engines, each requiring specific oil formulations to maintain optimal performance and longevity.

E90 328i Oil Type (2007-2011)

The E90 generation 328i features the naturally aspirated N52 3.0-liter inline-six engine, requiring BMW Longlife-01 (LL-01) approved oil^[1]. This specification ensures proper protection for the magnesium-aluminum composite engine block and VANOS variable valve timing system. The recommended viscosities are 5W-30 or 0W-30 full synthetic, with 5W-30 being the most common dealer choice.

These engines operate without turbochargers, running lower oil temperatures and pressures than newer models. The LL-01 specification provides the necessary detergents and anti-wear additives for BMW’s extended 10,000-mile service intervals, though many enthusiasts change oil at 5,000-7,500 miles for added protection.

F30 328i Oil Type (2012-2016)

The F30 generation marked a dramatic shift to the turbocharged 2.0-liter N20/N26 four-cylinder engine, introducing new oil requirements^[2]. While LL-01 remains approved, BMW also introduced fuel economy-focused LL-14 FE+ and LL-17 FE+ specifications for these models. The turbocharger’s extreme temperatures demand superior thermal stability and oxidation resistance.

The F30 accepts 0W-20, 0W-30, 5W-30, or 5W-40 viscosities, with dealers increasingly using 0W-20 for improved fuel economy. This thinner oil reduces internal friction while maintaining adequate protection through advanced additive packages specific to turbocharged applications.

N52 Engine Oil Type

The N52 engine’s all-aluminum construction with magnesium insert requires oils meeting strict corrosion protection standards^[3]. BMW LL-01 specification ensures compatibility with the engine’s Valvetronic system and Double-VANOS technology. Common approved oils include Castrol Edge 5W-30, Mobil 1 European Formula 0W-40, and Liqui Moly Leichtlauf High Tech 5W-30.

The N52’s relatively simple design without forced induction allows for wider viscosity tolerance, though 5W-30 remains optimal for most climates. According to Autvex maintenance experts, this engine demonstrates exceptional longevity when proper oil specifications are maintained.

N20 Engine Oil Type

The N20 turbo engine operates under significantly higher stress than the N52, with oil circulating through the turbocharger bearing at temperatures exceeding 400°F^[2]. BMW approves LL-01, LL-14 FE+, and LL-17 FE+ specifications, with the FE+ variants optimized for fuel economy through reduced viscosity.

The twin-scroll turbocharger requires immediate oil pressure at startup, making 0W-20 or 0W-30 grades particularly suitable for cold climates. The direct injection system also introduces fuel dilution concerns, making regular oil changes crucial for long-term reliability.

BMW Oil Specifications and Approval Codes

Understanding BMW’s complex oil approval system ensures you select products meeting stringent engineering requirements rather than generic “European” formulations.

BMW Longlife-01 (LL-01) Specification

BMW LL-01 represents the cornerstone specification introduced in 2001 for extended drain intervals^[1]. This approval requires oils to maintain viscosity stability, resist oxidation, and provide adequate wear protection for 10,000-15,000 miles under various driving conditions. The specification includes strict limits on sulfated ash, phosphorus, and sulfur content to protect emissions equipment.

LL-01 oils typically feature robust additive packages including zinc dialkyldithiophosphate (ZDDP) for anti-wear protection, though levels have decreased from earlier LL-98 specifications. The approval process involves extensive BMW testing including high-temperature deposits, fuel economy, and compatibility with seals and gaskets.

BMW Longlife-14 FE+ (LL-14 FE+) Specification

The LL-14 FE+ specification targets fuel economy improvements through reduced viscosity while maintaining protection^[2]. Introduced for turbocharged engines, this approval allows 0W-20 viscosity oils with friction modifiers optimizing efficiency. The “FE” designation means Fuel Economy, with the plus sign indicating enhanced performance characteristics.

These oils achieve approximately 1-2% better fuel economy compared to LL-01 equivalents through reduced internal engine friction. However, the thinner base oil requires more sophisticated additive technology to maintain protection under high-stress conditions.

BMW LL-01 vs LL-04 Comparison

While LL-01 suits most BMW 328i applications, understanding LL-04 helps avoid confusion:

Specification	Sulfated Ash	Best For	DPF Compatible	328i Usage
LL-01	Standard	Gas engines	No	All 328i models
LL-04	Low-ash	Diesel engines	Yes	Not recommended

LL-04’s reduced ash content protects diesel particulate filters but may compromise valve train protection in gasoline engines lacking DPF systems.

Full Synthetic Motor Oil Requirements

BMW mandates 100% full synthetic oil for all 328i models due to superior thermal stability, oxidation resistance, and flow characteristics^[3]. Synthetic base stocks maintain viscosity across wider temperature ranges while resisting breakdown under turbocharger heat stress.

Conventional oils cannot meet BMW’s extended drain specifications or protect sophisticated variable valve timing systems. Semi-synthetic blends similarly fall short of requirements, potentially voiding warranties if used.

BMW 328i Oil Approval Codes

When selecting oil, verify the bottle displays appropriate BMW approval codes:

• LL-01: Universal approval for all 328i engines
• LL-14 FE+: Fuel economy option for F30 models
• LL-17 FE+: Latest specification for newer turbo engines
• API SN/SP: Supplementary American standard
• ACEA A3/B4: European performance classification

Multiple approvals on one product indicate broader compatibility, though BMW-specific approval takes precedence.

Oil Viscosity Requirements by Model Year

Viscosity selection significantly impacts engine protection, fuel economy, and cold-start performance across different 328i variants.

BMW 328i 5W-30 Applications

The 5W-30 viscosity represents the most versatile option for BMW 328i engines^[4]. This grade suits:

• All E90 328i models (2007-2011)
• F30 328i in moderate climates
• Year-round use in most U.S. regions
• High-mileage engines requiring thicker oil film

BMW dealers stock 5W-30 as their primary service fill, with brands like Castrol Edge Professional TWS 5W-30 meeting LL-01 requirements.

BMW 328i 0W-30 Applications

The 0W-30 grade offers superior cold-start protection while maintaining high-temperature performance^[1]. Benefits include:

• Faster oil circulation at startup
• Reduced cold-weather wear
• Improved fuel economy versus 5W-30
• Suitable for all 328i engines with LL-01 approval

Northern climate drivers particularly benefit from 0W-30’s improved flow at temperatures below 0°F.

BMW 328i 0W-20 Usage

Modern F30 328i models increasingly use 0W-20 for maximum fuel efficiency^[2]. This ultra-light viscosity requires LL-14 FE+ or LL-17 FE+ approval, ensuring adequate protection despite reduced thickness. BMW specifies 0W-20 for:

• 2013-2016 F30 328i seeking optimal mpg
• Vehicles under warranty requiring fuel economy compliance
• Moderate climate operation without extreme loads

Some owners switch to 0W-30 or 5W-30 after warranty expiration for perceived better protection.

BMW 328i 5W-40 Compatibility

The 5W-40 viscosity provides enhanced high-temperature protection for specific applications^[4]. Consider 5W-40 for:

• High-mileage engines with increased clearances
• Aggressive driving or track use
• Hot climate operation
• Engines consuming oil between changes

Popular LL-01 approved options include Mobil 1 European Formula 0W-40 and Liqui Moly Synthoil 5W-40.

BMW 328i Oil Type for Cold Weather

Cold weather operation demands careful viscosity selection. For temperatures consistently below 20°F:

• Best choice: 0W-20 or 0W-30 with appropriate approval
• Acceptable: 5W-30 with strong cold-flow properties
• Avoid: 5W-40 unless specifically formulated for cold

The “W” (winter) rating indicates cold-flow capability, with lower numbers providing better sub-zero protection.

Specific Model Year Oil Requirements

Each model year may have unique requirements based on production changes and technical service bulletins.

2007 BMW 328i Oil Type

BMW 328i xDrive Oil Type

All-wheel drive xDrive models share identical oil requirements with rear-wheel drive variants. The xDrive system uses separate fluid for the transfer case and doesn’t affect engine oil specifications. However, xDrive models may experience slightly higher oil temperatures due to increased drivetrain losses, making quality synthetic oil even more critical.

Both E90 and F30 xDrive models follow standard specifications for their respective engines.
