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.

Used this on me n18 mini Jcw . It has helped them a bit but not fully cured it before I would get loads of white smoke when pulling away now I get a little bit, good to tie you over for a bit and would 98.8% recommend it but not worth the 5star

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..

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

I was getting an occasional but sizeable puff of blue smoke on start up. Tried this along with their oil fortifier. Made no difference at first but around 200-300 miles later the smoke stopped completely. Engine is a VW 1.9 waterboxer which doesn't have valve stem seals so not sure what the Forte did, but I'm happy with the results. I have since changed the oil so it's no longer in there but still seems fine.
