Mystik Heavy Duty Engine Oil Exceeds Emission Standards
New Mystik JT-8 Emissions Management Technology (EMT) engine oil is specifically formulated to exceed the American Petroleum Institute’s CJ-4 requirement for today’s high-performance diesel engines.

Available in SAE 15W-40, Mystik JT-8 EMT is the newest generation of heavy-duty engine oils from the Mystik line of lubricants.
A synthetic blend that stands up to a wider range of operating temperatures than conventional oils, Mystik JT-8 EMT delivers prolonged life for exhaust aftertreatment particulate filters in all 2007 and pre-2007 engines. Aftertreatment systems will require ultra low sulfur fuel and oils such as Mystik JT-8 EMT to meet the new emission standards.
Intended for use in heavy-duty service in commercial trucks, agricultural equipment, construction equipment, stationary engines and other diesel-fueled engine applications, other features of Mystik JT-8 EMT heavy-duty engine oil include:
• Additives to dramatically reduce engine wear.
• Superior oxidation resistance and thermal protection at extreme temperatures.
• Outstanding soot control.
• Meets manufacturers’ latest warranty requirements.
• Available in gallon containers and drums.
Mystik lubricants are manufactured by CITGO Petroleum Corp. CITGO, based in Houston, is a refiner, transporter and marketer of transportation fuels, lubricants, petrochemicals, refined waxes, asphalt and other industrial products.
