Frequently Asked Questions:

How long does it take to start working?

Rislone Engine Treatment Concentrate starts working the minute you install and start driving the vehicle to help remove harmful gum, sludge, and deposits from your engine.

How does Rislone Engine Treatment Concentrate work?

Rislone Engine Treatment Concentrate gradually dissolves and removes harmful deposits of varnish, sludge and gum from the internal metal parts without plugging oil passages. These deposits form within engines and can alter tolerances, stick valves and rings, cause noisy valves and lifters, and plug oil screens and passages. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum.

How much Rislone Engine Treatment Concentrate do I install?

One bottle of 4102 Rislone Engine Treatment Concentrate 16.9 oz. is designed to treat 4 to 6 quarts of oil. For larger systems, stationary engines and diesel trucks, use 1 bottle for every 5 quarts of oil capacity. For severely dirty engines, use 2 bottles (double dosage) of Rislone Engine Treatment Concentrate and change the oil and filter after 100 miles of driving.
