CD-2 4105R Stop Leak for Engine Oil - 15 oz.

Great stop leak. I remember when I could buy this for $3.00.

Good Job! Product used for what it was intended for.

To seal engine oil seals

I bought this around March 2012... I used it on my 2002 Harley Sportster in an empty oil bag... this meant I completely drained my used oil... then poured the entire CD-2 into my oil bag.Then I filled up with proper oil proper amount... and now I don't have a silly leak under my bike anymore.Oh I should say I was leaking some where under my bike about 4 to 6 drops per day... and my co-working-building would complain about me dripping oil everywhere.Now I don't drip at all. So I figure this stuff works. I recommend it to those who want to stop their leaks :P

have used cd-2 for many years, in my business. it works!!!

This worked as advertised, somewhat, but was nothing more than a temporary band aid. If your engine seals are worn, or damaged, nothing will save it from a visit to the "Grim Reaper" - the engine overhaul shop ): This observation also applies to the use of so-called high-mileage motor oils - expensive band aids that offer only short-term help. But something is better than nothing if the cost is not affordable, I suppose.

This is my favorite brand of oil additive ever. I have had leaks in many cars before and this has always been a cheap, effective product that sealed them better than others I tried in the past. Although pricey when online, it is well worth it.
