Rislone High Mileage 4 6 8 Compression Repair, 16.9 oz.

2007 H3 Hummer 186,000 milesThese 2 products (Look at uploaded picture) ACTUALLY WORKED. It was at 309 miles exactly of driving after a fresh oil change + these 2 oil additives-the check engine light went off and stayed off.The Hummer is an oil burner so I added another half quart of “ring seal”, check engine light is still off.* Rislone “ high mileage compression repair with ring”* Rislone “ high mileage Ring Seal Smoke Repair”___________________________________________Below was my issues and what I’ve tired to get the check engine light off.Aggressive HEAVY IDLING - Blue Smoke blowing out exhaust on start - - a mechanic said I blew a head gasket and that was going to cost $7000 to replace it or $12,000 for a new engine.I Changed 8 sensors - changed spark plugs and engine coils, check engine light was still on, I changed all the fuses. I cleaned the throttlebody, I made everything sure all was airtight sealed. I got some type of spray cleaner and sprayed it into the main PCV hose (90degree angle one).Nothing F’ing workedNow after the additives….My car almost runs like brand new and purrrrrrrs like a cat, I get better gas mileage, there’s no more heavy, rumbling or shaking.I’ll be adding these two additives every oil change.

Came on time. Everything is fine. Thank you very much!

It worked somewhat; I will definitely be using a 2nd bottle to see if it clears up more. Probably need 2 bottles for a 8 cylinder

I bought my 2009 SUV with 85,000 miles and now has 120,000. It has shaken at idle since the day I bought it. I've spent a lot of money replacing all the parts I thought could be causing it. Nothing worked. I knew I had low compression at 95 psi in one of my cylinders but thought there was nothing I could do except rip apart the engine and fix it. I did not know until a week ago that there was an oil additive I could add to see if it improved the performance of my engine. I added the compression additive to my engine oil and went for a ten minute drive. When I got home and parked in my garage there was just a little engine shaking and no more engine pinging. My engine would rattle my car to where it would spill water sitting in a cup in the cup holder. Now there is just a very slight shimmy. The difference is night and day! This stuff is awesome!!!! Edit: I just went on a two hour drive through the city and highways. I filled up the tank with regular gas. I got 31mpg after driving 130 miles. I've been getting 19-22 mpg and the best I ever got was 24mpg. This stuff is just amazing!

Is what it is.. same as at any auto parts store. Won’t fix a broken tired valve or ring.

This week, the shop told me that I had to get a new motor or spend x amount of money on having my cylinder #3 piston ring replaced because the compression test was poor, only producing 70psi. The did a valve adjustment when increased it to 90psi, but it didn't stop the timing on the engine from being very poor and causing the engine light to constantly blink. Before bringing the car, which is 1998 honda crv with 220K on the engine, to the shop for the misfire. 2 weeks before I had the timing belt replaced, which was pretty costly. So, long story short. . . I decided to go online and look at some addatives. I ran across Rislone High milage 4, 6, 8. Did an oil change and added the can. I was pretty excited. I started the car and ran it in town for about 10 miles. I noticed a little improvement in the idling, but it still caused the engine light to turn on. I have an obd II code reader, so I reset it and turned off the light. The next morning, I was driving my car to work and low and behold, there was no check engine light and the idle was smoother, when I came to a stop light. I'm like. . "Praise the Lord. . Thank you Jesus"! Also, thank you to the makers of Rislone. Now, I will be able to drive with peace of mind! God bless and Carry on. . from Salina, KS.

If you're here this is probably your last resort. It's not going to fix your problem but it may extend your engines life to get you down the road a bit longer. Definitely made our failing engine run quite and smoother. No noticeable increase in compression.

doesn't work at all waisting time
