Rislone 4102 Engine Treatment Automotive Additive, 16.9 oz

Been using this stuff since the 70's does just what it says it will do my grandma didn't change her oil like she should have clicking lifters put this in and sent her on her way next time she came by no noise coming from the engine pulled the dip stick and you could visually see where it was in the oil because that part of the dip stick was shiny clean! I had a 1966 Lincoln coupe that belonged to a Dr it sat for a while and was not driven much I got the car and it burned one quart of oil going over the pass to the beach and back less than 100 miles I put a bottle of this stuff in the crankcase drove it over the summit I went below the speed limit until I hit the final grade then put the pedal to the metal and let it go till I got to the top after I went home I topped it off and it loosened the rings and never burned a drop after that… This stuff is not snake oil it does what the label says it will do.

I started using Rislone as an additive to my oil change years ago. I had a BMW with a slight ticking sound. After adding the Rislone, it was gone. I became a firm believer and have been using ever since.

I added this product along with a quart of AT fluid to my daughters car. It had some sticky valves that were ticking and knocking. After a couple weeks, the car seems to be running a lot better.

I don't have many miles on my SUV, less than 64m (M=thousand), but I have 10 years on it. I wanted to help the initial starting & running of warm up, but adding this, with a snake oil. Except for the first bump start, it helps quiet the valves sooner than with out. You can always go with a lower W weight oil if you'd like, but this adds a few chemicals to the oil to help your engine along the way, getting into all of those little spots, & hopefully clearing those paths a little bit in the process. I have used this many decades ago on a higher mileage car & it did help get some oil into those harder to get to areas of neglect. You could see that when you took things apart, as well as the glops of sludge in the oil pan after adding it. Remember, this thins the oil out. I started with half the can first to see how it'd do. I added the rest about two weeks later, which helped it along better.

My wife's 2000 Toyota Corolla has the motor with sludge issues known by Toyota. It also has extremely loud lifter noise, especially under acceleration. I have been searching for years for a remedy. I found it !!. It's Rislone engine additive that can be added anytime. The car has been on Mobil 1 for many years, which has helped also. With the Rislone, the noise disappeared right away, on the very1st usage, poured in about 1/2 Qt. I believe that the car seems to have a better pickup also. My wife drives all city, all the time. Thanks so much Rislone, thanks much, we are expecting many more mile for this vehicle, which only has 86K miles. Great price, give it a try, worth the $5, easy, peezy.......

Want to clean out your motor slowly use this product, do it twice and if you have any lifter noise or anything it will clean it out

makes the engine more quiet, does not damage engine, I trust this product. I always use it every oil 6

Used this with an oil change and it did what it claims. Engine seems to run smoother and quieter. Easy to use and no issues so far. I'd buy it again.

I've had good luck with most Rislone products! So I figured I'd give it a try but I was wrong! I was very disappointed when I couldn't tell any difference at all after using it! I had lost my receipt or I would've tried the money back disappointment guarantee! I started to call just to tell them how bad they let me down! i felt like they ran over my dog and kicked my cat!

Did absolutely nothing for my son's 2014 Honda Accord EX-L with the VTC rattle on cold start up. Wont be buying any Rislerone products in the future.
