Is it a good or bad idea to use oil leak additives?

Lucas Oil Is the best for oil leaks, I wouldn't use anything else.Is it a good or bad idea to use oil leak additives?
Most of them work fairly well on small leaks. Replacing gaskets and seals is very expensive and can't gurantee they will ';fix'; the leak indefinitely.





Simply retorquing the screws and bolts that hold things together will often seal the problem leaks.





A common problem in older cars is the front and read main seals and replacing these is a waste of time and money unless you replace the main bearings that center the crankshaft inside the block. When the engine ages, there is wear and tear on these internal bearing surfaces and the crankshaft will ';sag'; or settle when the car is parked and this stresses the rubber seals on the crankshaft making them stretch and leak.





The only respctable gasket replacement I would consider is the valve cover gasket or anything that separates the coolant from the oil like an intake manifold gasket.





The oil leak stop additives are for relatively small leaks or drips. They will not stop a large leak that requires you to add a quart of oil and day or week to the crank case.

It might be a temperory fix but it depends on the main problem could be many things and i need more info to answer
no!those products are for theives and sheisters who are looking for a quick fix so they can sell a used car to some poor sucker.the seal conditioners actually swell any and all rubber componets o-rings,seals,etc. the problem is they never stop swelling the rubber. i own a transmission shop and i see this all the time it works for a little while then catastrophic failure!a little 1 in. diameter o-ring comes out about ten in. diameter. get your leak fixed the right way if you are keeping your car.if you are selling it be honest with the prospective buyer.
they're OK to use. it's usually just a rubber conditioner to soften seals. won't hurt anything, just don't get your hopes too high on it fixing the leak.
If you are talking about the A/C it won't hurt a thing so go ahead and install the leak test, hope this helps.
