Delo 400 XSP SAE Heavy Duty Synthetic Diesel Engine Oil 5W-40, 1 Gallon, Pack of 1

Delo 400 XSP synthetic SAE 5W-40 is API CK-4 heavy duty engine oil. It is fully compatible with previous engine models and previous API oil service categories. Delo 400 LE synthetic SAE 5W-40 is 100 percent synthetic engine oil which exceeds industry and engine manufacturer's performance requirements. It is formulated using the most advanced additive technology available to provide outstanding protection. Delo 400 LE synthetic SAE 5W-40 helps keep piston rings clean and free for optimum combustion pressure and minimal wear. Delo 400 LE synthetic SAE 5W-40 minimizes valve and piston crown land deposits, thus lowering oil consumption. Its high level of ashless dispersants keeps fuel soot in suspension and thus avoids filter plugging, cylinder head sludge, abrasive wear, viscosity increase and oil gelation. Delo 400 LE synthetic SAE 5W-40's anti-wear technologies protect against valve train wear and scuffing of highly loaded parts operating under boundary lubrication. A deforming additive prevents air entrapment. Delo 400 LE synthetic SAE 5W-40 is mixed-fleet motor oil recommended for all naturally aspirated and turbocharged four-stroke diesel engines and four-stroke gasoline engines in which the API CJ-4 or API SM service categories and SAE 5W-40 viscosity grades are recommended. It is formulated for engines operating under severe service and a wide range of climatic conditions. Delo 400 is excellent for use in new advanced engines developed to meet 2007 emissions standards and in engines equipped with features like; four-valve heads, supercharging, turbo-charging, direct injection, shorter piston crowns, higher power density, inter-cooling, full electronic management of fuel and emissions systems, exhaust gas recirculation, and exhaust particulate filters.
