Motor oil Castrol EDGE 5W-30 ACEA C3 BMW LL-04, synthetic, 4 L

Castrol EDGE 5W-30 ACEA C3 BMW LL-04 is a full synthetic engine oil formulated for modern petrol and diesel engines that require a low-SAPS formulation and BMW LL-04 approval. Supplied in a 4 L container, this oil is engineered to provide consistent lubrication across a wide temperature range, protect critical engine components from wear, and help maintain the performance of exhaust after-treatment systems. The formulation supports engine cleanliness and stable viscosity to assist fuel efficiency and reliable start-up protection.

Advantages

The oil delivers high film strength and reduced friction under high load, helping to minimise wear and extend engine life. Its low-SAPS chemistry is compatible with diesel particulate filters and catalytic converters, supporting emission system longevity. The synthetic base and advanced additives ensure good flow at low temperatures for faster oil circulation on cold starts and stable viscosity at high operating temperatures to preserve oil film and engine protection.

Suitable for

• Passenger cars with petrol engines requiring ACEA C3 or BMW LL-04 specification
• Diesel vehicles equipped with diesel particulate filters and catalytic converters
• Engines that benefit from low-SAPS lubricant to maintain emission control systems
• All-season use where a 5W-30 viscosity grade is recommended by the manufacturer

Key specifications

• Viscosity grade: SAE 5W-30
• Specification class: ACEA C3
• Manufacturer approval: BMW LL-04 compatible formulation
• Type: Fully synthetic motor oil
• Container size: 4 litres
• Low-SAPS (reduced ash, sulphur and phosphorus) additive system

How to use

Check the vehicle owner’s handbook to confirm that ACEA C3 and BMW LL-04 compatible 5W-30 oil is suitable for your engine. Warm the engine to operating temperature, then switch it off and allow a few minutes for the oil to drain back to the sump before checking the level. Drain the old oil and replace the oil filter if required, then refill with the specified quantity of Castrol EDGE 5W-30 4 L until the correct level is reached. After refilling, start the engine, let it idle briefly and recheck the level, topping up if necessary. Dispose of used oil and filter according to local regulations.

Recommendations

Use this oil for vehicles explicitly requiring ACEA C3 / BMW LL-04 grade 5W-30 and follow the manufacturer’s service intervals. For optimal performance, pair with the correct oil filter and avoid mixing with oils of significantly different specifications.
