I’ve been using this product for over 15 years. It’s definitely as increase the life of my engine. I have a 1994 Jeep Wrangler S it has over 267,000 miles and it runs like a champ does not burn oil and the lifters are very quiet All due to this product. I only recommend using this product during oil changes.

Ran this for 3 oil changes In my 2009 Sierra 5.3L, 2013 Yukon 6.2L, and 2001 Tahoe 5.3L. They are all high milage, the 6.2L had 255,000!Within the first three oil changes with full synthetic oil and 1 container of Rislone, all lifter chatter was gone and piston slap sound when cold was gone. Also oil consumption between changes is next to nothing on all 3! GREAT PRODUCT!

It’s hard to tell for sure if any fluid works for an engine issue, but in this case, I believe this fluid did quiet the ticking.

Amazing product- I've been looking for something to help keep valves from sticking with todays synthetic oil. At 144K miles this seems to be doing the trick! Beats a engine teardown. Quick shipping!

I have owned a total of six cars, all purchased new, since 1975. I have rarely found that any additive is worth buying. My current car is a 2016 Subaru WRX Base trim line. It has 72,500 miles, which averages to about 9,000 miles per year. Over the last three years or so, I noticed a ticking sound out of the engine and I could feel a slight vibration in the steering wheel when sitting idle. So, for the first time in years, I started looking to see if there was an additive that could treat this. I had to be careful because this car uses synthetic oil and I didn't want to void any warranties. I found that the Rislone checked both those boxes and the reviews seemed very positive. I purchased this in June 2024, but didn't get around to trying it until last week, when I had an oil change. I am truly amazed. Within a week, the engine quieted down and I feel no vibration in the steering wheel. I haven't monitored the gas mileage yet, but even if it didn't increase, the change in noise and vibration made the Rislone a great purchase. I unconditionally recommend this product. It worked like magic.

I have used this for years in an old pickup that has a sticky lifter. It works very well.

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.

It seems to work! Regardless, after years of using synthetic Mobil 1 oils, my Highlander started making a valve noise when starting up. Disappointed, I bought this, hoping it would quiet the noise. To my surprise, it did. I am not sure how long it will last. It is not that it is just my head, but I will definitely use it at every oil change from now on. Small price for peace of mind,
