This product contains high quality penetrating oil, combined with protective engine additives and special cleaning agents.

Its multi-grade formula allows oil to flow freely and provides protection over a broader temperature range.

Additional Product Info

Rislone® Engine Treatment is high quality penetrating lubrication oil, combined with protective engine additives and special cleaning agents. Its multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range. Sludge and other harmful deposits within engines can alter tolerances, stick rings, cause noisy valves & lifters, and plug oil passages and screens. The unique Rislone formula is designed to penetrate into bearing surfaces, piston rings and ring grooves, where sludge and varnish is likely to form. These deposits are gradually removed and held in suspension until they are trapped in the filter or removed with the next oil change. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum. A cleaner engine is a better lubricated engine with less friction
& wear.

Works on gasoline and diesel engines with conventional, high mileage and synthetic engine oils.

INSTRUCTIONS: (Automotive Applications)
Adding To Existing Engine Oil—Remove engine dipstick and check oil level. If oil is low, remove oil cap and install entire contents of bottle. Do NOT overfill. Reinstall dipstick and oil cap.
When Changing Oil—If using when changing oil, replace one quart of your motor oil with Rislone Engine Treatment.

For best protection, use Rislone Engine Treatment at every oil change.

DOSAGE:
In passenger car and light truck engines, use one bottle for a 4 to 6 quart system. Example: If using when changing oil and you have a 5 quart crankcase capacity, use 4 quarts of oil and 1 quart of Rislone Engine Treatment.
For larger systems, stationary engines and diesel trucks, use at 20% of crankcase capacity. For severely dirty engines, use two quarts of Rislone Engine Treatment and change the oil after 100 miles of driving.

“I have a personal Rislone story. Customer called, and his motorhome was running great when parked in fall, would not start in spring. I checked it out and found bent pushrods, then found valves stuck in guides. I tried hitting with mallet, stuck solid. Had friend suggest putting Rislone in oil can and squirt around valve guides. Long story short, came in next morning, tapped with mallet, valves were free, replaced push rods and all was well. I added Rislone every oil change no more problems. Chrysler 440 1970s been using and recommending since. ASE master auto, master heavy truck and engine machinist great stuff.”

“Best On The Market! I drive a 2010 Chrysler Town and Country with 200,000km . It starting having a lifter tick at start up, it Would last a few minutes then go away. In the last week it has gotten louder, not wanting to remove the cam shafts to replace them I decided to try Rislone Engine Treatment. Within days it is a night and day difference. The engine runs smoother and quiet. I will keep a bottle on hand for every oil change for now on.”

“Thanks for the great products. Hello I would just like to take a min to let you know how happy I am with your product I have a 2002 Chevy Astro with a 4.3 it always had a little rocker nock when I put it away in the fall. I got her out and there was the nock no big deal well I went on a little trip to Niagara Falls and shut off the engine when I started it up I had the worse nock I really thought I had a lifter collapse I had ok oil pressure so I drove slowly home. Well I went on YouTube to see what it might be I was told to use Rislone oil additive, put  it in let it run then drain the oil then put in a little heaver oil and another bottle of Rislone. Well I did that but I didn’t drive it anywhere until today when I started up it had the knock so I thought well that didn’t work. Well let me tell you by the time I got home, I put about 80 mi on new oil and the knock is gone it runs so quiet and I’m so happy I was thinking I was going to need new lifters and rocker arms but I’m good to go. I’m sure that without your product this would not have happened so thank you for this amazing product Rislone. It will be my only oil and gas additive I will use from now on. Again thank you!”
