Need a quick reference for your MerCruiser oil capacity? PartsVu’s Mercury MerCruiser Engine Oil Capacity Chart specifies oil capacity for your specific engine and serial number range. Simply select your engine family, then make sure you are reviewing the correct serial number range for the engine you own.
MerCruiser oil capacity varies by engine size, model year, oil pan, installation angle, and whether the oil filter is changed. The safest approach is to start slightly below the listed capacity, run the engine briefly, allow the oil to settle, and confirm the final level with the dipstick.
Common MerCruiser Engine Oil Capacities
A MerCruiser 3.0L engine typically takes about 4 US quarts of oil with a filter change. Mercury 25W-40 NMMA FC-W marine engine oil is commonly recommended for reliable protection in marine operating conditions.
A 4.3L MerCruiser engine typically takes about 4.5 US quarts of oil with a filter change. Because capacity can vary by model year, oil pan, and engine angle, add oil gradually and verify the final level with the dipstick.
A MerCruiser 5.0L V8 usually takes 4.5–5.5 US quarts of oil with a filter change. Newer 5.0L MPI models often use about 4.5 quarts, while some older EFI or carbureted models may require closer to 5–5.5 quarts.
A MerCruiser 5.7L engine typically uses 4.5–5.5 US quarts of oil with a filter change. Mercury/Quicksilver 25W-40 NMMA FC-W marine engine oil is commonly recommended, with the exact capacity depending on model year and configuration.
A MerCruiser 350 MAG usually takes about 4.5–5.5 US quarts of oil with a new filter. Many 2002-newer models use around 4.5 quarts, while some older EFI or MPI configurations may require closer to 5.5 quarts.
Most 7.4L MerCruiser engines require about 7 US quarts of oil with a filter change, although some configurations may take up to 8 quarts. Common marine oil choices include 25W-40, 15W-40, or 20W-50 depending on the engine and operating conditions.
A MerCruiser 454, also known as a 7.4L engine, typically takes 6–8 US quarts of oil with a filter change. Many EFI and MPI models use about 7 quarts, while some older or high-performance configurations may require more.
