For that extra protection needed in four cylinder and high performance engines, Motor Purr Heavy Duty Motor Oil Stabilizer has you covered. This special product is a premium, 100% petroleum-based, full formulated oil stabilizer that decreases harmful friction and engine wear, while increasing oil pressure and compression. Use Motor Purr Heavy Duty Motor Oil Stabilizer in semi-trucks, motor homes, SUV’s, tractors and other heavy duty farm and Earth moving equipment.

Motor Purr Heavy Duty Motor Oil Stabilizer is many times thicker than regular motor oil and provides a layer of protection several times greater than standard motor oil. This product blends with all automotive lubricants: synthetic and mineral oils. This greater oil viscosity helps improve oil pressure, increase engine compression and improve gas mileage.

This product coats the internal parts of the engine and does not all go back to the oil pan. That’s why the oil level on the oil dip stick will not increase on the dip stick. This protective layer protects the engine against friction, improving gas mileage while reducing exhaust emissions.

Add 1 Quart of Motor Purr Heavy Duty Motor Oil Stabilizer in any 3 to 6 quart system at every oil change or between oil changes as needed.
