Forte Lubricants Car Rear Crankshaft Seal Oil Leak Conditioner - 125ml

Very good, it doing as it said.

I was sceptical at first, but did the trick. My car was burning oil every 500miles would need like 1litre . Common problem I discovered on bmw e90 2.0i . So used it and the problem gone, so been driving over 2 weeks and the oil is still bang on. Highly recommend it each oil change. Especially for older cars with high mileage.

Think my valve stem seal are too far gone, still smoking after using. To be fair though have only run the car weekly, not taken it out for long runs, due to being SORN and MOTless. Will update once I do.

I got two tubes of this stuff as I suspected my stem seals were failing but it turned out to be a faulty glow plug module. However, my garage uses Forte branded treatments all the time and swears by it. I have a 3.0 E65 so two tubes were required but I feel assured that this stuff is a good precautionary thing to use to prevent any potential issues down the line.

Didn't take long to work on my 98 dodge ram with 250.000 miles I would recommend it to a friend

Added to engine oil. I had a small leak. After driving around 300 km leak is stopped

MY 630i e63 2007 BMW is fine without any dilemmas, but I take know chances when it comes to my immaculate pride & 😊 joy,so once a year I oil change service & add 2:of these forte babies with 2:bottles of zx;friction eliminator & my engine runs smoother than a brand new car, with know exhaust smoke, just steam & water vapour from my twin pipes people, not bad for a car that's 15:years old..

This didn’t work on my car. It still burns oil as witnessed by blue smoke. It’s supposed to soften seals such as the valve guides. Maybe it work for some, but not for me. So I couldn’t recommend it.
