Rislone 100QR Engine Treatment Conditioner and Cleaner 32oz Bottle (6 Pack)

Do I have to flush my oil after using Rislone Engine Treatment Concentrate?

No, Rislone Engine Treatment Concentrate is formulated to be left safely in the crankcase for the life of the oil change for maximum performance. It is not an engine flush and does not require draining.

How does Rislone Engine Treatment work?

Rislone Engine Treatment 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 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.
