Just because your car is older or has a lot of miles doesn't mean it can't perform like it used to. Remember the good old days. Get them back with a can of Rislone High-performance oil treatment. This high-viscosity formula was specially developed for older and higher-mileage engines to improve their performance so you and your car can have many more good days. Performance doesn't have to diminish with age and we can prove it. We've been proving it for over 90 years. This high-viscosity formula increases oil film thickness, building a thicker oil cushion and increasing oil pressure in mid- to high-mileage engines. Increased oil pressure equals increased power and a quieter-running engine. Not to mention, the Rislone high-performance oil treatment cushions and coats engine internals to reduce friction and wear by preventing metal-to-metal contact between moving parts, giving your vehicle longer engine life.
