Designed for easy use, simply add two tubes to your engine oil and drive to activate a microscopic repair process proven over 10 years in commercial applications. Ideal for preventing costly engine overhauls and extending engine life with minimal effort. ## Description Blow by, using oil, lack of power and low compression are the first signs of engine wear. Don't get caught having to get an expensive overhaul or replacing the engine. 2 tubes come for this purchase. The latest engine technology repairs the engine with ceramics and actually reverses engine wear while you drive. CerTech Gels have been proven in over 10 years commercial use, So no matter what you drive, your engine wear is showing signs of the high miles you have put on it. You may be adding oil all the time, dealing with blowby, being bothered by rod knock noises or just tired of the sluggish performance. No matter, CerTech Gels engine repair kits have been fixing those problems for years without having to spend $3,000 to rebuild your engine. You simply add one tube of the Gel into the oil and drive. After about 100 miles, you add a second tube and enjoy the smoother, quieter, more powerful performance. (Did we mention better fuel economy?) It really is that simple. The chemistry is in the Gel. Every time metal hits metal in the engine (trust me, it does on each power stroke) a microscopic patch is formed to rebuild the engine wear. After thousands of hits, the parts start to take on their original shape and create new engine performance. Don't worry, the building stops once optimal tolerances are reached. With a 100% safety factor over 10 years you will be pleased to know that no engine has ever been damaged. We absolutely stand behind these engine repair kits because we have seen so many customers get the results that you are looking for. Call us and a trained professional will handle any questions you have. Now it is your turn. Compression is recovered as the rings and cylinders regain their factory spec tolerances. Bearings and journals are resurfaced too. No more smoking, blowby or rod knock. Just add the CerTech Gels and drive your way to a new engine. 4 and 6 cylinder engines require 2 tubes. Significant engine wear may require an additional tube. Review: Took the Chance...Glad I did. - Had morning start-up blow-bys. Watched Youtube and read the blogs. Pulled the trigger and bought the 8 cylinder kit directly from CerTech. Glad I did. During the first tube injection the daily morning blow-bys were less and less often. After the initial first tube oil change (100-200 miles) and the injection of the second and third gel tubes the puffs of noticeable smoke appears to be virtually gone. It works, at least for my car (E38). Happy with the results so bought another kit to keep the wife's car in tune and in shape. Prevention is the best maintenance. Review: tried it on 2 vehicles one with engine knock other ... - tried it on 2 vehicles one with engine knock other with blowby neither worked the car with blowby 04 altima caught fire eventually ## Features - Top selling engine repair kit by far!! Increased power and reduced oil between oil changes. Resurfaces engine wear areas that cause using oil, low compression, blow by and low oil pressure. Engine ceramics actually add back material and bond to the metal surface. Simply add to the oil and drive. This is the next generation of engine repair and maintenance. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00H3OEGW4 | | Brand | CerTech Gels | | Customer Reviews | 3.9 3.9 out of 5 stars (22) | | Date First Available | February 14, 2016 | | Is Discontinued By Manufacturer | No | | Manufacturer | CerTech Gels | | Manufacturer Part Number | 4-and-6-cylinder | ## Images ![4 and 6 Cylinder Engine Repair Gels - Image 1](https://m.media-amazon.com/images/I/71Y8ZMdouNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Took the Chance...Glad I did. *by A***T on July 12, 2016* Had morning start-up blow-bys.
