Saved a fortune
Great product my car had been sitting for a while and when I started it after being in storage for 12 months it started to smoke blue smoke spoke to my mechanic about it and he told me to run this in for a while after a oil change then add another after 3 months it rejuvenated the rubber valve stems seals now it does not smoke anymore saved a fortune on having valve stems dune

Wow it works, saved me a lot of money
So impressed by this stuff, I have a e92 BMW it was throwing out a lot of blueish smoke after idling; indicating the stem seals have a small leak. Using this stuff and using thicker oil, completely fixed the issue. I am so impressed by this, its the best £17 I have ever spent I think.

Mixed bag
I'm losing a bit of oil all of a sudden on my 1 series - given it's low mileage, I thought this couldn't hurt, at least until the next oil change in a couple of thousand miles. Hard to say if this has worked, i didn't use the oil fortifier beforehand, and didn't apply it to fresh engine oil( 4.5k miles). I've done a couple of hundred miles and haven't noticed any alarming usage - so I'll continue to keep an eye on it. Other than that, I'll use a thicker grade oil and hope that sorts it.

Was sceptical. Great product.
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.

Seems to have improved my engine
I didn't have any symptoms with my engine warrenting me to buy this, but my engine had done 106,000 miles, so I took a punt and added this, more as a preventative measure. Now, when I added this product my engine had a couple of foibles, but after driving 2-300 miles I've noticed the foibles improve a little, one of those appears to be improved oil pressure, although I would need to test that properly to confirm my hearsay; fingers crossed. Anyway, time will tell...
