## Overview

Rislone High Mileage Compression Repair Seal (Pack of 1, Model 4447) is a premium USA-made engine oil additive designed to restore compression in worn engines. Its advanced polymer formula fills cylinder wall imperfections, stabilizes compression, repairs engine blow-by, and helps improve fuel efficiency and emissions compliance for both gasoline and diesel vehicles.

## Description

Rislone High Mileage Compression Repair Seals are a unique concentrated blend of high shear and premium polymers developed for high fuel consumption engines who suffer from lower compression and uneven disturbance. Low compression can be caused by normal engine wear and a drop of seal between the piston ring and cylinder wall. Non-dispersive Olefin Copolymer fills scratches and grooves in the cylinder walls to increase and stabilize all cylinders Compression repair plays worn out engines, rebuilds compression, restores lost power, and repairs engine blow-by. In addition, compression repairs help vehicles pass emission tests. Signs of low compression include power loss, low fuel consumption, oil consumption, blue smoke caused by exhaust, plug dirt, engine noise and vibration. Viscosity Enhancer (VI) is specifically designed to provide the optimum balance of shear stability and thickening efficiency required by older engines and modern engines. This high performance additive meets the most demanding engine requirements of passenger cars and trucks. Release the adhesive ring to fill in gaps and scratches in cylinder walls, eliminate blow-by, compression loss, and reduce friction and wear. Blow by is typically caused by gaps in internal engine parts due to excessive wear. Rislone compression repair with ring seal contains no harmful lead or other metals that can damage the engine interior and burn or pollute emissions and the environment. Works with gasoline and diesel engines using traditional high fuel consumption and synthetic engine oils.

## Questions & Answers

**Q: Can you use this product and the anti-friction product at the same time?**
A: Hello, and thank you for your question. We appreciate you considering Rislone for your automotive needs. Since you don't specify which anti-friction product you are asking about, it's difficult for us to give you a complete answer. What we can say is this: Rislone High Mileage Compression Repair (part number 4447) IS compatible with Rislone Nano Prime Engine & Oil Additive (part number 4104), which uses Nano Tungsten and Moly to reduce friction up to 38%. We have not tested the Compression Repair with products from other manufacturers, so we are not able to address possible compatibility concerns in that area.

We hope this satisfactorily answers your question. If you have any other questions or would like additional information on these or any of our products, please feel free to call our Tech Support Team at 1-800-345-6572. We are here to assist you Monday through Friday, from 8 am to 5 pm Eastern time.

**Q: Can i use (mix) this product if i am using xl nanolube engine oil additive & nano treatment; reduces oil burning & engine smoke**
A: Thank you for your question and for considering Rislone Compression Repair with Ring Seal (part number 4447) to help with your automotive needs. We cannot recommend these two products be mixed as we only have test data on compatibility within our own family of products. Since we don't test the efficacy or compatibility of our products alongside a competitors product, we can't advise you to use them together. We certainly appreciate your interest, but as a family run company for over 70 years, we pride ourselves on being honest with our customers - if we don't think we can help you, we will let you know, and in this case, we can't.

**Q: Do i put in every oil  chang or is it a 1 time and done**
A: Every oil change.  I have an 87 Toyota Corolla with 200k, it takes 3 at this point.  I have observed that it works after the first trip.  It has eliminated blue smoke and low oil pressure.  "Your mileage may vary".

**Q: Is it safe to use in engines with variable valve timing? Like a 1997 Honda Prelude**
A: Thank you for your question, and for considering Rislone to help with your Honda.
