WT OIL – API: CH-4/SJ
SEMI SYNTHETIC

WT Oil CH-4/SJ semi synthetic is heavy duty diesel engine oil which helps to protect against the build-up of piston deposits for continuing engine efficiency. Exceeds performance limits in piston ring, cylinder liner and valve train wear tests for long engine life.

Application

These heavy duty engine oils are recommended for all types of diesel and gasoline engines where the manufacturer specifies the API service API: CH-4/SJ. They are especially suited for use in low temperature environments where extreme pump ability properties are required. These oils are also suitable for on-road and off-road application, including equipment that are exposed to extreme low temperature operations. This oil is suitable for use in moderate to high sulfur content fuel.

Features & Benefits

• Improved oxidation stability to minimize deposit formation
• Higher TBN to extend protection from acids caused by combustion
• Better protection against valve train wear
• Improved low temperature performance
• Potential fuel economy improvement compared to conventional CH-4 heavy duty engine oils
