Engine Treatment

My 2017 Expedition has 220,000 miles and the lifters started clattering loudly on startup. I added Rislone after the last oil change and after driving it for awhile the clattering has completely gone away. Highly recommend this product

I own a lot of cars. I'm always looking for something useful. This is one of those. Fat pig of a 2000 V8 Explorer appreciated it, got its rated 16MPG. Quieted the weird squeal from the cam bearings. Our turbo Volvos like it. The 2015 broke 32MPG. the 2004 is at a solid 22.5 The rototiller likes it. Small Honda was quieter and cooler. The Ford 860 Tractor burns less oil Would recommend. Its on a subscription now. Would recommend.

Had a metallic clicking noise start in my van on the end of a 3 hour drive. Research suggested lifter was gunked up. Poured the whole bottle in the oil, and clicking stopped about 4 seconds after starting the van! Been about 3 days of normal driving and it has not returned. Never leave reviews but this stuff worked awesome! Vehicle: 1993 Chevy g20 5.7L with 150k miles

Works ok, add at oil change, good detergent additive

just what I needed

Does everything it says it does ! Oil smelled sour before now stays clean and smells fresh after 2000 miles . Engine much quieter the instant I poured it in while it was running . Super smooth. High rislone quality like always

I put it in my car and it met expectations

Benefits aren't many but the one I wanted was to quiet down some noisy lifters. Worked for all of 1 hour before they went back and there's no traces of the stuff left in the oil at all.

جيد لكن ماراح اشتريه مره ثانيه و ماله تأثير واضح

I have a Engine Tick and this stuff is Keeping my Engine Running good I will be using every oil Change and the price you can't beat very happy .

It is a very good product, a little pricey but it’s a personal choice like any product

Good and good product for 8 cylinder car machine

Best product to quiet noisy lifters. Worked in minute's. Will be buying it for all my oil changes.
