    About this item

    Product details

    Delo 400 XLE SB SAE 15W-40 with ISOSYN Advanced Technology is a high-quality synthetic blend engine oil. It's designed for extended drain intervals up to 1.5 times longer than OEM standards and is suitable for mixed fleets. This oil is ideal for diesel engines requiring API CK-4 or SN service categories and SAE 15W-40 viscosity. It has approvals from major heavy-duty Original Equipment Manufacturers, meeting their latest engine oil specifications. This makes it a versatile choice for various engine types. It provides exceptional deposit control, maintaining clean pistons and turbochargers. The oil also ensures better low-temperature pumpability compared to conventional SAE 15W-40 oils, with improved flow and similar pour point to SAE 10W-30 products, offering better cold flow properties.  

    Overall, Delo 400 XLE SB SAE 15W-40 delivers value through its extended drain performance, exceptional deposit control, better low temperature pumpability, and compatibility with a wide range of engine models and previous API Oil Service Categories. Delo 400 XLE SB SAE 15W-40 with ISOSYN Advanced Technology offers significant cost savings through minimized operating expenses. Its exceptional soot dispersancy and wear control ensure that engine components like cylinders, pistons, rings, and valve trains are well-protected against wear and corrosion, leading to optimal service life and reduced maintenance needs. This contributes to maximum equipment use with minimal downtime.

     The oil also excels in emission control, providing long Diesel Particulate Filter (DPF) life, which translates to less downtime and cleaning, effectively managing maintenance costs. It is backward compatible with previous API Oil Service Categories, offering a single solution for heavy-duty stationary engines and Allison off-highway transmission performance. It's suitable for a wide range of engines, including various diesel engines, which simplifies inventory and dispensing systems, potentially saving money, space, and handling time.

    Delo 400

    I have used Cheron RPM Delo for 5 decades now without one oil related problem. It's a low ash, high detergent oil that I have chosen for everything from high performance air cooled VW engines to literally every heavy duty application I've come across.
