Worked perfectly on my q7 ! Saved me 1000s as it would of been a engine out job ! 2 bottles as my engine holds 8 litres and worked and sealed almost in the same day ! Fully sealed the next day ! I will be buying 2 more bottles just to have lying around ! 1000% number 1 product for me ! Awsome

My oil leak seems to be worse after using this stuff would not recommend at all, I’ve used other products with much better results

Hi have added to oil so far leak appears to have stopped, no drips below car now. Engine running good, mpg improved by 3 miles a gallon

its far too expensive for what it might do, it did'nt work for me, maybe if i had put three bottles in the engine it might have worked but at that price i'm afraid not, so i would,nt try it again. thank you.
