BMW M440i Convertible Engine Oil Guide
The BMW M440i Convertible was produced from 2021 to 2026. This model typically uses 0W-40 full synthetic engine oil — a specification common to most BMW M44-series vehicles.
Selecting the correct oil viscosity for your BMW M440i Convertible is essential. Using a grade that is too thin reduces protection at operating temperature, while too thick an oil impairs cold-start flow and reduces fuel economy. Always match the exact grade shown for your specific model year.
The recommended oil change interval for the BMW M440i Convertible is every 10,000 miles or 12 months. Under severe driving conditions — track use, towing, or frequent cold starts — shorten this interval by 25–30%.
When servicing your BMW M440i Convertible, always replace the oil filter at every oil change. Using a premium filter — such as the Mann or Mahle filters specified for European engines — ensures proper oil pressure.
Oil change costs for the BMW M440i Convertible at a US dealership or independent European specialist typically range from $120 to $200 for a full synthetic service. DIY oil changes cost approximately $30–$65 in parts (oil + filter) and take about 30 minutes with the right tools.
Always consult your vehicle's owner's manual to confirm the exact specification for your specific trim and engine variant, as some BMW M440i Convertible configurations may have different requirements.
BMW engines require BMW Longlife-approved full synthetic oil. Using non-approved conventional oil can damage the variable valve timing (VANOS) system and void your warranty.
BMW engines may consume small amounts of oil between services. Check the oil level via the iDrive display or dipstick every 1,000 miles to avoid running low.
