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.

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.
