Rislone's Engine Treatment Concentrate provides all the benefits of the original Rislone Engine Treatment in a bottle that is nearly half the size. If left untreated, engine develop sludge and other harmful deposits that can plug oil passages, alter tolerances and cause rings to stick. This treatment can travel where sludge and varnish are likely to form, including valve seats, bearing surfaces, piston rings and ring grooves. Comes in a 16.9 fluid ounce bottle, designed 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.
