Castrol Assuron (SAE 10W, 20, 30, 40, and 50) are high performance, heavy-duty engine oils that couple selected base stocks with a carefully balanced additive package. Castrol Assuron (SAE 10W, 20, 30, 40, and 50) by design will enhance engine performance and protect engine parts for extended life and reduced maintenance costs. Castrol Assuron (SAE 10W, 20, 30, 40, and 50) has proven performance in various on-and off-highway heavy-duty diesel engines, particularly in applications requiring API CF-2.
Castrol Assuron (10W, 20, 30, 40, and 50) are extremely resistant to the formation of high temperature deposits. The higher dispersant package also works to keep the cooler areas of the engine from sludge and other harmful deposits.
Castrol Assuron (10W, 20, 30, 40, and 50) exceeds the requirements of the following API categories: SAE 10W (CF), 20 (CF), 30 (CF-2, CF), 40 (CF-2, CF), 50 (CF-2, CF). Castrol Assuron meets the requirements of General Motors Corp. (Allison Trans. Div.) C-4.
Castrol Elixion, a revolutionary SAE 5W-30 synthetic engine oil, is formulated with a polyalphaolephin (PAO) engineered base fluid that is free from wax, metals and sulfur.
PAO base fluids are known for their extremely low pour points and high viscosity indexes of 140 or better. A high viscosity index gives the finished lubricant optimum viscosity over a range of temperatures, as well as wear protection during extreme high and low temperatures.
Castrol Hypuron redefines the standard for super high performance diesel engine oils for on- and off-road equipment of all ages. Castrol Hypuron has been uniquely formulated to meet the demanding needs of diesel power units regardless of the equipment's application. Castrol Hypuron offers maximum engine protection and the associated cost efficiencies of safely extending drains. It is distinctively capable of delivering these results by utilizing a Castrol-engineered additive package, while exceeding API CJ-4 requirements.
Castrol Hypuron Advanced Formula 10W-30 combines Castrol’s unique formulation with a high quality,
semi-synthetic base oil to deliver measurable performance benefits to fleets large and small. While
formulated for the latest low-emission diesel trucks, buses, and other over-the-road vehicles, Castrol
Hypuron Advanced Formula 10W-30 also provides outstanding protection for older diesel engines too.
