## Description

Have you noticed oil leaking from your car lately? Many car owners fear the puddle they see forming under their vehicles, and many worry about the time and cost to make it go away.

Our Bar’s Leaks Concentrated Rear Main Seal Repair quickly and safely restores those seals so you can get back on the road.

At Bar’s Leaks, we do everything we can to get you back on the road in good condition just as quickly as possible, by offering rear main seal leak products and much more.

Not to mention, it works with ALL gasoline and diesel engines using conventional, high mileage and synthetic oil.

**Q: Can you use this with synthetic oils**
A: Yes, I have used it with synthetic oil with no issues.

**Q: What it does with my other gasket that has not have a leak?**
A: If I'm understanding your question correctly.... you would like to know what effect this has on gaskets that are not leaking?    The answer is nothing.....  Thank you  Eric

**Q: Is this safe to use with other gas additives such as seafoam, lucas?**
A: Yes there is no problem. This gets poured into your oil crankcase not into your gasoline. Seafoam usually gets poured into your gas tank to clean injectors and cylinder walls sometimes you can put it in the crankcase just about 4 oz to clean junk this does not stop any leaks usually done 100 or 200 mi before an oil change. Lucas has many products some that are injector cleaners that go into the fuel tank some that are oil stabilizers or stop leaks or friction additives that go into your oil crankcase you can have Lucas oil additive/stop leak and bars leak in your oil crankcase they don't interfere with one another
