A Version of “The Legend”
This is it – a version of what made Rislone famous. The cleaner you keep your car’s lubrication system, the better it runs. Our famous, award-winning Rislone Engine Treatment does just that. 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. The unique Rislone formula is designed to penetrate into valve seats, bearing surfaces, and piston rings, where sludge and varnish are likely to form. These deposits are removed with the next oil change.
Part Number: 4102
Dosage: In passenger car and light truck engines, use one bottle for a 4 to 6 quart system. For larger systems, stationary engines and diesel trucks, use 1 bottle for every 5 quarts of oil capacity.

Additional Product Info
Rislone® Engine Treatment Conditioner and Cleaner 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, diesel and turbo engines with conventional, high mileage and synthetic engine oils.

“No More Noise! I got a 2002 GMC savanna 3500 cutaway 125,000 miles. I noticed a ticking noise in the v8 5.7 gas vin r. It was noticeable . I researched your product today, bought it put it in. OMG PERFECT very quiet. Thank You!”
“This Stuff Works! These 5.3 L are known for lifter noise. Last night I went to Walmart and installed the 4102, drove 75 miles last night and started it up this morning and it did not have any noise at start up. I drained the oil out today. Lucas, Sea Foam, Slick 50 and Marvel, ATF and never helped. This stuff worked.”
“Great Product! I checked out your product on the internet to loosen a stuck lifter 2012 5.3 liter and figured had nothing to lose. It says 1 bottle treats 5 liters so my truck takes 7. So I put 2 bottles in, took it for a one hour ride, put it in tow haul mode to really work it. When I got back I let it cool for 2 hours. It started, no noise, was gone completely next morning when block was cold started. Noise gone and it was really noisy before. Thank you very much you saved me from a tear down! I recommended this product to my friend who has been a Dodge mechanic for 15 years and he told me to try transmission fluid.”
I have a 2010 Mazda CX7. I added a bottle of the Rislone High Mileage Engine Treatment about 1000 miles after I got the oil changed. Drained half a quart of oil and added the Rislone. After about 25 minutes of the engine running I could tell the engine was running quieter. After 175 miles the engine is so quiet you can’t tell it’s running. The car is even starting easier. Great product.
