Rislone 4102 XTREME LUBE® Maximum Performance Engine Treatment, 16.9 oz.

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.

Quieted a knock in my engine, did its purpose. Easy to use, worth the money.

Have an 8.1 Vortec thats had the lifter tick the entire time I've owned it. Bought this on a suggestion, and within 30 seconds the lifter tick went away. Incredible.

Works ok, add at oil change, good detergent additive

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.

En cada cambio de Aceite....le pongo este aditivo, protección para las partes metálicas del motor.

I love this stuff...it's like giving your engine a bath. I drive a lot, so I do this in the middle of every oil change..HIGHLY recommend!

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.
