So I have oil leaking from what I believe to be my rear main on my Honda Civic, I used UV dye and found oil coming out of my transmission bell housing gasket, and my clutch slips some days and not others probably because it has oil on it.. and the rear main is about the only way it would get in there. Its not a bad leak, I lose maybe a quart every 1500 miles, I was wondering do oil leak stopping additives work? and which one would be best for my application?

Stop leak additives are generally just oil thickeners which just mask the problem. Some have had good experiences with Valvoline Maxlife oil, which contains seal conditioners to slow or stop leaks.

+1

Do a MaxLife oil change and let it do its thing. Your Civic is the perfect example of a vehicle that would benefit from a HM oil, with 200K miles on the clock.

Maybe just repair the leak and change the gasket.

No, they don't have "seal swell agents" in them.

Ya, they do.

From Valvoline Max Life Synthetic blend bottle:
"Seal conditioners help reduce oil consumption and leaks"

From QS Higher milage engine oil bottle:
"Reduces oil consuption through worn or leaking seals"

Read up on this. It is for leaks as well as oil burning, the company has a solid reputation too. It's worth looking into.

Definetely try Re-Seal by ATP.. it's not a thickener and I have real world results from it.

The only success I've had with any stop leak product is Lubro Moly Oil Saver. I highly recommend it.
