I put Lucas Oil power steering stop leak, transmission stop leak and crankcase stop leak in my car last weekend and was just wondering if anyone knew if these additives were all the same. They look the same. They are all red and they're all as thick as STP oil additive. Maybe thicker. Any ideas?
Stop leak additives may work for a while.
They basically soften hard seals. The
problem is, they don't stop softening,
and your seals turn to mush and will
eventually leak worse. If the seal is
torn, or has chunks missing out of it,
no amount of stop leak is going to
work. And there are some seals where
stop leak will have no effect at
conditioning or softening depending
on their composition. These stop leaks
aren't all the same. I've not used Lucas,
but have used Blue Devel. It stopped
a transfer case leak I had until I could
afford the time and $$ to fix it the right
way. Just my .02...
