Delo 400 SD SAE 15W-30

SAE Grade: SAE 15W30
Delo® 400 SD SAE 15W-30 is a premium and innovative diesel engine oil intended for engines that have duty cycles which qualify as "severe duty." These include reducing idling time by turning the engine off at stops or deliveries, stop and go in heavy traffic or city delivery, or situations where engine cooling may be stressed like when towing heavy loads or when cycling between fully loaded and unloaded in off road applications.

    Detailed Product Description


    Severe Duty — Intended for severe duty applications like reducing idle time by turning the engine off at stops or deliveries, stop and go in heavy traffic or city delivery, towing heavy loads, or situations where temperatures of engine components are high. Severe duty applications typically have lower drain intervals relative to other duty cycles. See OEM recommendations for drain interval recommendations.
    Exceptional oxidation and deposit control — Exceptional oxidation stability and deposit control help protect piston ring belt zones and turbocharger bearings. Contributes to maximum vehicle utilization and minimal downtime.
    Improved fuel economy — Tests show comparable fuel economy to SAE 10W-30 in (Class 6) stop and go applications and up to 0.7% fuel economy improvement with long haul trucks (Class 8) when compared to a SAE 15W-40 oil.1
    OEM approvals — Carries a range of OEM approvals.
    Excellent emission control system life — Provides optimum Diesel Particulate Filter (DPF) life for minimal downtime and cleaning, thus managing your maintenance costs.
    Managed inventory costs — Backwards compatible with previous API Oil Service Categories and engine models where XW-30 oils are appropriate as noted in the OEM recommendations. Suitable for use in four-stroke gasoline and naturally aspirated, turbocharged and modern electronically controlled/low emission diesel engines. Allows users with a wide mix of engine brands to enjoy simplified inventory and dispensing systems that may contribute to saving money, space and handling time.
    Warranty Plus protection — Bumper-to-bumper warranty protection from the engine to the drive train. Payment for Chevron lubricant-related damage to your equipment, including parts and labor.2 Problem resolution and technical advice from Chevron’s lubrication experts.


    Delo 400 SD SAE 15W-30 helps keep rings clean and free for maximum combustion pressure and minimal wear. It minimizes valve and piston crown land deposits, thus managing oil consumption. Its high level of resistance to oxidation helps to avoid filter plugging, corrosive wear, heavy 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.

    Delo 400 SD SAE 15W-30 is uniquely designed to minimize oxidation, sludge, and undue thickening in severe duty applications. Its unique blend protects against valve train wear and scuffing of highly loaded parts operating under boundary lubrication. Its resistance to oxidation and resulting deposit control help protect in hot engine components.


    Delo 400 SD SAE 15W-30 is a mixed fleet motor oil recommended for naturally aspirated and turbocharged four-stroke diesel engines and four-stroke gasoline engines in which the API CJ-4/SM service category and SAE XW-30 viscosity grade is recommended. It is formulated for engines operating under severe service and a wide range of climatic conditions.
