Castrol EDGE Euro Car 5W-40 A3/B4 Motor Oil
Full Synthetic SAE 5W-40 European Motor Oil for Gasoline and Diesel Engines
Castrol EDGE Euro Car 5W-40 A3/B4 is an advanced full synthetic motor oil formulated for gasoline and diesel engines that require an SAE 5W-40 lubricant meeting ACEA A3/B4, API SP, or other compatible manufacturer specifications.
European automakers often require engine oils to meet specific performance standards beyond viscosity grade alone. Castrol EDGE 5W-40 A3/B4 carries approvals from BMW, Mercedes-Benz, Porsche, Renault, and Volkswagen, making it suitable for a range of European vehicles where one of these specifications is required.
The formulation is designed to provide wear protection under high pressure, reduce friction across varying engine speeds and operating conditions, maintain thermal stability and viscosity control throughout the drain interval, and help reduce engine deposits.

Why European Oil Specifications Matter
Two motor oils can both carry an SAE 5W-40 viscosity grade while meeting very different manufacturer requirements.
Castrol EDGE Euro Car 5W-40 A3/B4 carries approvals including BMW Longlife-01, MB-Approval 229.5, Porsche A40, Renault RN0700/RN0710, and VW 502 00/505 00. These approvals help buyers identify whether the lubricant is suitable for engines requiring those exact specifications.
When selecting a European 5W-40 motor oil, confirm the manufacturer specification in the owner's manual rather than choosing based on viscosity alone.
Storage
Store packages under cover. If outdoor drum storage is unavoidable, Castrol recommends storing drums horizontally to help prevent water ingress and protect package markings. Do not store the product above 60°C or expose it to hot sun or freezing conditions.
