Intended Use
For Volvo Penta four-stroke gasoline marine engines whose operator’s manual or service documentation specifies full-synthetic SAE 10W-40 engine oil. Suitable for both sterndrive and inboard installations when this viscosity and oil type are specified.
Not intended for use as sterndrive gear lubricant, transmission fluid, hydraulic oil, or diesel engine oil unless the applicable Volvo Penta documentation specifically authorizes its use.
Compatible Applications
Confirm the required viscosity, specification, and crankcase capacity using the engine model, serial number, and current Volvo Penta operator’s manual. Oil requirements can vary by engine generation, operating temperature, and emissions configuration.
- Volvo Penta gasoline marine engines manufactured after 2002 where SAE 10W-40 full-synthetic is specified
- Volvo Penta GXi, OSi, and related gasoline sterndrive packages (confirm by serial number)
- Volvo Penta IPS gasoline pod-drive applications (confirm by serial number)
- Multi-engine and twin-engine installations requiring bulk oil supply
Service Interval
Replace engine oil and filter at every 100 operating hours or annually, whichever comes first. Always follow the interval specified in your Volvo Penta engine operator’s manual for your specific model. More frequent changes may be appropriate after prolonged idling, overheating, fuel dilution, water contamination, or severe-duty use.
Installation Notes
Warm the engine as directed in the service procedure and extract used oil completely before refilling. Replace the engine oil filter at the same service. Refill gradually to the specified capacity, run the engine, check for leaks, allow the oil to settle, and verify the level with the vessel in the position specified in the operator’s manual. Do not overfill. Keep the container sealed between uses. Dispose of used oil through an approved recycling facility.

Technical FAQ
Q: What viscosity is this oil?
A: SAE 10W-40 — confirm this is the viscosity specified in your engine’s operator’s manual before ordering.
Q: Is this oil suitable for diesel Volvo Penta engines?
A: No — this formulation is for gasoline marine engines only. Diesel engines require a different Volvo Penta oil specification. Refer to your operator’s manual.
Q: How much oil does my engine take?
A: Crankcase capacity varies by engine model. Refer to your Volvo Penta operator’s manual or engine specification sheet for the correct fill quantity.
Q: What is the difference between 21681796 and 21681795?
A: Part 21681795 is the 1-litre single bottle. Part 21681796 is the 5 US gallon (approximately 18.9 litre) bulk container. Both are the same full-synthetic SAE 10W-40 formulation.
Q: Can this oil be used year-round?
A: SAE 10W-40 is suitable for year-round use in most marine climates where this viscosity is specified. Confirm with your engine operator’s manual for extreme cold-weather operating conditions.
Parts Desk Insight
The 5-gallon size works well for larger-capacity engines, twin-engine setups, or service shops running multiple oil changes in a season. Calculate your exact fill quantity from the engine specification before opening the container — total crankcase capacity is not always what it seems when you account for the filter. Keep the pail sealed between services and never mix with coolant, transmission fluid, or used oil of unknown specification. If you’re unsure whether your engine takes this viscosity or a different grade, check the oil cap, the dipstick label, or the operator’s manual — the grade is almost always printed somewhere accessible.
