Lubegard LG-Fixx Seal Fixx Multi-Purpose Stop Leak, 8 fl. oz

Previous oil change I used ATP Automotive AT-205 Re-Seal Stops Leaks. Slowed the leak down didn't stop it. I added a bottle of Barr's Stop leak. Still leaking too much so I added a can of STP Stop Leak Slowed the leak to a small drip. Next oil change I added STP high mileage Stop Leak As a safety measure. Maintained a slow leak on this oil change So it took three different formulas of companies to Stop the Leak to get to a slow drip. After 10k an another oil change with Mobile synthetic oil. I added a bottle of ATP Automotive AT-205 Re-Seal Stops Leaks. As Online reviews say this is the best oil stop leak. I noticed it was dripping but I didn't want to deal with it. After 2000 miles I was down 1 1/2 quarts of oil. Back to doing research on oil stop leak. So I checked videos online by mechanics and their testing. Order the bottle of Lube Guard Seal Fixx. Read instructions. Engine must fully warmed up before pouring in. Reading and recommendations Poured the 8oz bottle into the oil with the car running. I let the car run for 2 hours idling in my driveway. Then I went out for about an hour running in errands Then slid a large piece of cardboard under the car. No drips no leaks. This stuff works better than the any others I've used. I'll follow up later So far it's the best. It's a 5+-hour job to replace the leaking gasket. The gasket part is $200. And I don't want to deal with 5+ hours of disassembling and reassembling to replace gasket

No complaints but it’s not easy to tell if it’s working as described. Didn’t stop the small rear engine seal leakage in my 25 year old Chevy Tracker but may have reduced the drip some.

Good product and service

I've used Lubeguard treatment in the past for my transmission not holding on hills and worked great! Too soon to tell if lubeguard seal fixx works?? I have to give it time.

This stuff does wonders. Have used it in oil, radiator and transmission and it stopped the slow leaks. No more spots on the pavement where I park. Will keep it on hand for sure. Easy to use and works!

After seeing this mentioned by Scott Kilmer, I poured the bottle of Seal Fixx into a spray bottle and treated all the door and other rubber seals and boots on the vehicle. I could hear a different in wind noise from the seals on the highway and the rubber did seem softer than before. One bottle was about the right amount to treat a vehicle.

Ran 2 bottles through my engine oil system over a couple weeks. Did nothing to stop the slow leak. Still leaking about 1cup every 10-12hrs of runtime.

Didn't notice much of a difference but my valve seals were LONG LONG gone. Sold the truck with it still blowing white smoke. Would be good for a less severe case of dry rotted seals.

Toller Shop. Sehr kundenfreundlich und zuvorkommend.

best sealer, have tried all .this one works, period!
