The Mercedes-Benz GL320 CDI 4matic was produced from 2007 to 2008. This model typically uses 5W-30 full synthetic engine oil — a specification common to most Mercedes-Benz GL3-series vehicles.
Selecting the correct oil viscosity for your Mercedes-Benz GL320 CDI 4matic 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 Mercedes-Benz GL320 CDI 4matic is every 5,000 miles or 6 months. Under severe driving conditions — track use, towing, or frequent cold starts — shorten this interval by 25–30%.
When servicing your Mercedes-Benz GL320 CDI 4matic, always replace the oil filter at every oil change. Using a quality filter — such as the Mann or Mahle filters specified for Mercedes-Benz engines — ensures proper oil pressure and prevents unfiltered oil from circulating through the engine.
Oil change costs for the Mercedes-Benz GL320 CDI 4matic at a US dealership or independent European specialist typically range from $120 to $200 for a full synthetic service. DIY oil changes cost approximately $60–$90 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 Mercedes-Benz GL320 CDI 4matic configurations may have different requirements.
Mercedes-Benz 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.
Mercedes-Benz 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, especially in older models.
