Rislone Releases Concentrated Version Of Flagship Engine Treatment

One 16.9 fluid ounce bottle is enough to treat a four- to six-quart oil system.
HOLLY, Mich. — Rislone’s newest concentrated product, Engine Treatment Concentrate, provides all the benefits of the original Rislone Engine Treatment in a bottle that is nearly half the size, according to the company.

“We found we were able to significantly reduce the amount of base oil in Rislone Engine Treatment without lessening the product’s protective performance,” said Clay Parks, vice president of development for Rislone. “This allows us to use smaller bottles and keep prices as low as possible for our customers. The concentrated version has the same lubricants, additives and cleaners as the best-selling original that motorists have trusted for more than 90 years.”

If left untreated, sludge and other harmful deposits can plug oil passages, alter tolerances and cause rings to stick. Rislone Engine Treatment Concentrate is formulated to penetrate areas where sludge and varnish are likely to form, including valve seats, bearing surfaces, piston rings and ring grooves, the company says. The deposits are held in suspension until they are trapped in the oil filter or removed during an oil change.

One 16.9 fluid ounce bottle is enough to treat a four- to six-quart oil system. Simply empty the contents into the vehicle’s oil fill spout. Noisy lifters and valves will be noticeably quieter after installation, according to the company.

Rislone Engine Treatment Concentrate is compatible with all four-, six- and eight-cylinder gasoline or diesel engines. For maximum protection, it should be used after every oil change.

Like all Rislone products, Engine Treatment Concentrate (P/N 4102) is made in the U.S.A. It is available to distribution in case packs of six bottles. The label includes directions in both English and Spanish.
