Stop Leak Products: AT-205, Lucas, Bardahl, Liqui Moly, Bar’s Leak, Lubegard, Hapco, Blue Devil, XADO, Seal Lube, CD-2, Justice Brothers, Wynn’s. Do “Stop Leak” Products Work? Do they cause damage to engine seals? Will they destroy an engine? Stop leak products compared for their ability to condition or soften hardened rubber engine components, impact on new rubber engine parts, ability to resist evaporation under normal engine operating conditions, and film strength or the ability to lubricate engine components. I buy all of the products and the supplies used to perform the testing to ensure an unbiased review. So, thank you for supporting the channel!

Oil seal damage is irreversible, why can't we ban these products already?
Okay this has got to be a good one. He's testing Scotty Kilmer's favorite, atp 205
I had a 4.0 OHC Ford that was leaking a small stream out of the intake manifold onto the front of the engine. I put in a can of K-Seal powder and the damned thing stopped leaking in 5 minutes. Lasted a full year when I added more and stopped it again. Did not plug the heater core either.
As always, great, practical testing. Thanks.
LMAO love how some products did worse than literal snake oil
a large paving/mining company I worked for a few years ago had a couple older guys in the truck shop who would put a bottle of bars-leak in the coolant at every oil change.They had an issue with overheating on a few trucks, pulled the plug on the rad and nothing came out-the mechanic had to shove a screwdriver in the hole to break up the junk and get it to drain
Trans X is good stuff 👍
2:27 4:47 That will do some major damage on a morning start up…..
Scotty kilmer has talked about that 205 stuff a couple times.
do you have a video on what additive quiets a motor down internally, like noisy lifters, a possible spun bearing or piston pin noises?
"Much newer vehicle" like 2014 to the present?
A toolbox test could be cool but expensive for you. I'd like to see how the us general and hypertough look next to snap on and matco
