- Delo® 400 XLE SAE 10W-30 with ISOSYN® Advanced Technology is a premium synthetic blend fuel economy and mixed fleet engine oil recommended for naturally aspirated and turbo charged four-stroke diesel engines and four-stroke gasoline engines in which the API CK-4 or SN service category and SAE 10W-30 viscosity grade are recommended.
- Delo® 400 XLE SAE 10W-30 with ISOSYN® Advanced Technology is also recommended for off highway applications when SAE 10W-30 viscosity grade is required. It is formulated for newer engines with Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems. These newer engines generally meet Tier IV (2014) emissions requirements. It is fully compatible with previous engine models and previous API Oil Service Categories.
The following applications whenever the manufacturer recommends SAE 10W-30 grade:
- Modern on highway low emission designs as well as some older engines.
- Modern off highway engines where an SAE 10W-30 viscosity grade is recommended, including those adapted for stringent emissions standards in construction, agriculture, marine, and mining applications.
- Excellent performance in Auxiliary Power Units (APUs) found on trailer refrigeration (refer) units or on truck tractors to help reduce main engine idle.
