Concentrated Rislone Engine Treatment

Rislone Engine Treatment Concentrate (P/N 4102) from Bar’s Products is formulated to penetrate areas where sludge and varnish are likely to form.

One 16.9 fluid ounce bottle is enough to treat a four- to six-quart oil system. The product is compatible with all four-, six- and eight-cylinder gasoline or diesel engines.

Rislone Engine Treatment Concentrate is effective at removing sludge in valve seats, bearing surfaces, piston rings and ring grooves. The deposits are held in suspension until they are trapped in the oil filter or removed during an oil change.
