Rislone 4447 High Mileage Compression Repair with Ring Seal, 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.

My car started shaking and running really rough. My mechanic said it was loosing compression and it would cost over four thousand dollars for a used engine and installation. I bought this after reading the reviews and thought, why not. It took a month and now my car is running good again. My gas mileage is even back to what it was! I’d give it 10 stars if I could.

Works as advertised, smoothed out engine. Used in lawn tractor.

Great product, quick shipping

Bought a can for my okd Subaru Forester when it developed compression issues. Although it didn't cure the issue, it did help noticeably. I couldn't have aAdked any more of it for the price.

Stops oil consumption
