Improved Fuel Efficiency Reducing internal friction is a direct path to better fuel economy, and 5w40 synthetic diesel oil excels in this area. Performance in Extreme Conditions For vehicles subjected to severe operating conditions, 5w40 synthetic diesel oil proves its worth.
5w40 Synthetic Diesel Oil Engine Protection Level
The number preceding the 'w' signifies the oil's flow characteristics at low temperatures; a '5w' grade flows well at -30°C, facilitating easy cold starts and reducing engine wear during ignition. However, always consult your vehicle's owner manual for the manufacturer's specific recommendations regarding oil specification, such as API CK-4, FA-4, or the newer emission standards.
This combination makes 5w40 ideal for regions experiencing significant seasonal temperature variations, providing reliable performance year-round. In hot climates or during heavy towing, the oil's resistance to thermal breakdown prevents thinning, maintaining a protective barrier and preventing oil consumption.
