Review on High Mileage Engine Treatment: Restore Your Vehicle'S Performance With Rislone 16.9 Oz! by Christopher Yap
Worst idea ever - my new review
I'm pretty sure this is what destroyed the engine in our truck, I wouldn't ever buy again or accept as free from someone May not significantly increase vehicle lifespan.
Pros
- My valve train was getting very noisy at 100k miles. This stuff quieted it up and I'd recommend it.
Cons
- May not significantly increase vehicle lifespan
