High-speed, four-stroke engines
Delo® 400 XSP SAE 5W-40

Delo® 400 XSP SAE 5W-40 is a mixed-fleet engine oil recommended for naturally aspirated and turbocharged four-stroke diesel engines and four-stroke gasoline engines. It helps keep piston rings clean and free for optimum combustion pressure and minimal wear. A high level of ashless dispersants keeps fuel soot in suspension and helps to avoid filter plugging, cylinder head sludge, abrasive wear, viscosity increases, and oil gelation. These problems could cause excessive engine wear and bearing failure, without warning. Optimized additive chemistries combined with synthetic base stocks control oxidation, sludge, and undue thickening between oil drains. A de-foaming additive helps prevent air entrapment.

Performance Benefits

1. Low Viscosity Synthetic Base Stock

Promotes consistent cold engine starting for gasoline and diesel engines operating in sub-zero temperatures.

2. Minimized Operating Costs

Good soot dispersancy and wear control protect the cylinders, pistons, rings, and valve train components against wear and corrosion, promoting optimum service life and minimal maintenance. Contributes to maximum vehicle utilization and minimal downtime.

3. Good Emission Control System Life

Promotes optimum Diesel Particulate Filter (DPF) life for minimal downtime and cleaning, thus helping to minimize maintenance costs.

4. Managed Inventory Costs

Compatible with previous API Oil Service Categories. Suitable for use in gasoline engines and naturally aspirated or turbocharged electronically controlled/low emission diesel engines. One oil that meets the engine performance requirements of most North American and European engine manufacturers. One oil that allows users with a wide mix of engine brands to enjoy simplified inventory and dispensing systems that help save money, space and handling time.
