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

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!

This stuff really works.

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.

stopped my leak

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

This product works exactly like the ATP-205 Re-Seal additive at a cheaper price. I've used ATP-205 Re-Seal additive for many years until it got so popular that a shortage occurred, which eventually led to a big increase in price. I then decided to try Lubegard's version, and it works the same way as ATP at a cheaper price -- can't go wrong.

Have tried other stop leaks for rear main seal on 2006 Silverado and this one has worked the best! Had a big leak and it is now almost gone.

I used this product as instructions. Seems safe, oil consumption issues not get worse but no improve. Guess this not work on GDI engine.

Toller Shop. Sehr kundenfreundlich und zuvorkommend.

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