Is it OK to use 5w20 + Stop Leak instead of 5w30 oil in a H22A engine?

I've got a 1993 Honda Accord 2.2L L4 with 201k miles. Burns absolutely zero oil, perfect engine compression, silky smooth and quiet, but has some oil leakage. Instead of running recommended 5w30 oil, would it be acceptable to run 5w20 or 0w20 + Bar's Stop Leak (gasket seal) to prevent oil leakage? My car leaks a crap-ton of oil (up to a quart every 400 miles) - except with stop leak, in which case it leaks zero. I need the stop leak to prevent massive oil leakage, and can't fix the gaskets themselves right now. Would 0w20 (plus additive) be better than 5w30 to prevent the oil weight from going too high?

Id put the 5w30 in it

Better to get the leak fixed properly rather than sticking in horrid gunge and the wrong grade oil.

HI so just how dumb you it is not leaking so much as smoking the oil. That idea has about much success as you getting a bra

I see you're out to ruin a perfectly good motor! WTF is wrong with you people? You act like you can give "medicine" to a mechanical object instead of replacing the parts that are bad! Stop leak products in oil are more likely to plug up oil pump pick up screens before they even have half a chance to stop a leak that has 170 pounds of compression blowing through the leak!

It shouldn't be necessary to use a lower viscosity oil when using stop-leak product because stop-leak products don't make the oil THAT much "thicker" to slow/stop leaks in the first place. They stop leaks primarily by swelling seals and gaskets, not by making the oil thicker. If, say, you just ran really thick (20w50 for example) oil in the engine, it would still leak out because thicker oil viscosity doesn't prevent leaks.

If you're putting off repairing the cause of the leak and stop-leak product actually keeps it from leaking short-term, I'd just go ahead and use the 5w30 oil you've been using along with the stop leak. Just be sure that if the stop-leak bottle is ~16oz. (half a quart), add 16oz. (half a quart) less oil when changing out the oil next so that the crankcase oil level isn't filled too full. Running a thinner oil will probably do more harm than good.
