(2 pack) Rislone 4102 Engine Treatment Automotive Additive, 16.9 oz

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 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.
