I'm looking for oil stop leak for my tcase and front axle. I used White Shepherd on my previous disco, with good success. I bought it at O'Reilly's a few years back. But now, none of the O'Reilly's in my area have it. They do have Red Devil, which looks suspiciously just like the White Shepherd bottle. Very similar labels, designs, etc. Are they the same product?

 

Are you sure it's not BLUE Devil? That appears to be what White Sheppard re-branded as: Amazon.com: BlueDevil Oil Stop Leak: Automotive

 

The oil leak product is good. The Blue Devil coolant sealer is much more of a problem than other ones on the market.

The oil leakz stopz works by swelling the rubber slightly, here's an O-ring soaked in it for a day or two.

 

Oops, meant blue devil. Maybe they'll rebrand as red devil next year.

So it sounds like they're the same. Guess ill give it a try.

 

I was wondering what the heck this stuff did... thanks for sharing.
