How much Rislone Engine Oil Stabilizer w/ Engine Treatment do I install?
In passenger car and light truck engines, use one bottle for a 4 to 6 quart system. Example: If using when changing oil and you have a 5 quart crankcase capacity, use 4 quarts of oil and 1 quart of Rislone Oil Stabilizer with Engine Treatment. For larger systems, use at 20% of crankcase capacity. For severe problems or badly worn engines, double the dosage using up to 50%.
