FREQUENTLY ASKED QUESTIONS
RISLONE ENGINE TREATMENT
P/N 100QR

Do I have to flush my oil after using Rislone Engine Treatment?
No, Rislone Engine Treatment 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.
Will Rislone Engine Treatment work in synthetic oil?
Yes, Rislone works with all petroleum-based motor oils including conventional, high mileage and
synthetic. Rislone is also safe for use with PTFE-based engine treatments and will not alter the PTFE
coating.
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 much Rislone Engine Treatment do I install?
One bottle of 100QR Rislone Engine Treatment 1 quart (32 oz.) is designed to treat 4 to 6 quarts of oil,
this allows you to replace a quart of motor oil at oil change time. You can also use it to "top off" or add to
your system between oil changes. Do NOT overfill. For larger systems, stationary engines and diesel
trucks, use at 20% of engine oil capacity. For severely dirty engines, use two quarts of Rislone Engine
Treatment and change the oil after 100 miles of driving.
Is Rislone Engine Treatment safe for my newer vehicle?
Yes, Rislone Engine Treatment has the lubricating and protective capabilities of current motor oils, plus
additional penetrating properties which do a superior job of maintaining long-term cleanliness and deposit
control. Use of Rislone Engine Treatment will not void your new car warranty.
