May drop oil pressure
roy✓ Verified Purchase•April 19, 2024
stuff actually works after application and driving about 200 miles i have practically no leak. only con is it did drop my oil pressure significantly after vehicle is driven and warmed up. Probably due to the thinness of the product.
Worked amazingly

I added this to my old trail / woods rig, 2002 zr2 blazer. I'd take this rig out on the highway and about 10 mins the oil would be leaking on my exhaust and looked like a coal train going down the highway. I had a combo leak of oil pan gasket seeping and my rear main seal . I put this in and ran about a hour the first day. Noticed an improvement. I drove this 2 more days in row for several hours. This has not only stopped my coal train from smoking but it's down to a hardly visible tiny little oil spot . I can actually drive down the highway , not just the back trails now but I don't see or smell any oil burning onto my exhaust anymore. This saved me a ton of money for my old rig. I'm not sure about others but this stuff worked outstanding for me . Simple as pour it in and drive . I also used the trans sealant and it worked just as good . Blue Devil products worked wonders for me, great stuff !
I can't believe it works

I have a 13 year old manual transmission Honda Fit. Fantastic car all-around.
The clutch was replaced professionally 2 years ago and recently, I started to experience clutch slip only on cold start. Once slip a couple times in the morning; after that, the clutch grabs fine under all conditions for rest of the day.
Google search gives a likelihood that it's caused by small amount of oil leaked onto flywheel from rear main seal overnight. After slip once or twice, the oil is removed by the clutch disc friction and it runs fine after that. That's the theory anyway.
I figure nothing to lose to give this product a try. I poured in and ran the car normally for a couple weeks. HOLYMOLY the clutch slip on cold start is nearly gone.

Update March 8, 2024
Two months after the first usage and one oil change later. The clutch slip problem is resurfacing. This product does not present a permanent fix as advertised, but still works to an extent.
Rating changed to 4 stars.
