About Volvo Penta Engine Efficiency
- Fuel usage increases significantly at higher RPMs.
- Optimal cruising RPM is generally 2000-2500 for most marine diesel engines.
- Twin engine setups double the total consumption if both engines operate equally.
- Maintenance, hull cleanliness, and load all impact efficiency.
Example: A Volvo Penta D6-370 engine at 2500 RPM typically consumes 25 L/h under normal conditions.
