Rislone 4102 Xtreme LUBE® Maximum Performance Engine Treatment, 16.9 oz, 5-Pack

This high quality penetrating lubricant reduces friction and wear, quiets noisy lifters and valves and removes and prevents sludge. Its multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range. Use anytime, at or between oil changes. 2X concentrate, same performance as the 32 ounce size.

• REDUCES FRICTION AND WEAR: Multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range
• REMOVES AND PREVENTS SLUDGE: XTREME LUBE Maximum Performance removes sludge and other harmful deposits within engines that can alter tolerances, stick rings, cause noisy valves & lifters, and plug oil passages and screens
• QUIETS NOISY LIFTERS: The unique Rislone formula is designed to penetrate into bearing surfaces, piston rings and ring grooves, where sludge and varnish is likely to form. These deposits are gradually removed and held in suspension until they are trapped in the filter or removed with the next oil change
• QUIETS NOISY VALVES: Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum
• MADE IN THE USA: Will not void manufacturer's new vehicle
