Ultra1Plus™ SAE 15W-40 Full Synthetic Heavy-Duty Diesel Engine Oil

Advanced Protection for Your Engine: Ultra1Plus SAE 15W-40 Full Synthetic Heavy-Duty Motor Oil provides exceptional protection against oil oxidation, shear-induced viscosity loss, and aeration. It also safeguards against catalyst poisoning, particulate filter blockage, engine wear, piston deposits, and viscosity changes caused by soot. This oil ensures that your engine remains in top condition, even in harsh operating environments.

Superior Performance: Formulated with synthetic base oils and a premium additive package, Ultra1Plus SAE 15W-40 Full Synthetic Heavy-Duty Motor Oil exceeds the performance standards of API CK-4, CJ-4, CI-4, and CI-4 PLUS. It effectively lubricates engines requiring these service categories, ensuring reliable performance and protection for your machinery.

Stay-in-Grade Performance: The strong shear stability of Ultra1Plus SAE 15W-40 Full Synthetic Heavy-Duty Motor Oil guarantees stay-in-grade performance. This means the oil maintains its viscosity and continues to protect your engine against thermal breakdown, even at high temperatures.

Reduced Oil Consumption: Our full synthetic motor oil minimizes oil consumption under all driving conditions. This reduces the need for frequent oil top-ups and changes, saving you time and money while keeping your engine running efficiently.

Versatile Use: Designed for high-speed four-stroke cycle diesel engines, Ultra1Plus is perfect for engines meeting 2020 model year on-highway and Tier 4 non-road exhaust emission standards, as well as for previous model year diesel engines. It excels in sustaining the durability of emission control systems, especially in setups with particulate filters and advanced after-treatment systems.
