Delo SAE Heavy Duty Motor Oil 30W, 1 Gallon, Pack of 1

Chevron Delo 400 heavy duty motor oils are exceptional, super premium quality "universal" engine oils which exceed industry and engine manufacturer's performance requirements. They are formulated utilizing the most advanced additive technology available to provide outstanding engine protection under both pre and post-1998 EPA standards for exhaust particulate emissions for on-highway diesel trucks, using both high and low sulfur diesel fuels. Chevron Delo 400 SAE 10W, 20, 30, 40, and 50 are manufactured using carefully selected premium paraffinic base oils and an optimal blend of the latest technology in dispersant, detergent, oxidation inhibition, anti-wear, corrosion inhibition, and deforming additives. Chevron Delo 400 oils keep rings clean and free for better combustion pressure and to provide minimal wear. Their high level of ashless dispersants keeps fuel soot in suspension and thus avoids filter plugging, heavy cylinder head sludge, abrasive polishing wear, high viscosity increase, and oil gelling. These problems can result in excessive engine wear and bearing failure on startup, without prior indication to the operator. Applications: Chevron Delo 400 oils are mixed-fleet motor oils recommended for all four-stroke gasoline diesel engines operating under severe service and subjected to wide variations in climatic conditions. Chevron Delo 400 oils are excellent for use in new advanced engines developed in response to 1998 lower exhaust particulate emissions with features such as four-valve heads, turbo charging, retarded fuel injection timing, direct injection, shorter piston crowns, higher power density, peak firing pressures up and beyond 2300 PSI, inter-cooling, full electronic management of fuel systems, and exhaust particulate traps. Chevron Delo 400 oils are also formulated for superior performance in older engines using normal, high, and low sulfur diesel fuels. Chevron Delo 400 oils are not recommended for use in DDC two-stroke engines.
