    Rated 1 out of 5 by from DOES NOT WORK Bought this wynns product as it is a trusted name and have used engine flush etc in the past with good results, No wonder this stop smoke engine oil treatmant was reduced it does not work at all, it has been circulating in the engine for 2 weeks and if anything smoke has got worse, don’t waste your money.

    Rated 5 out of 5 by from Good stuff But don't ask the world of it! I have used this in my transit connect 1.8tdci and it worked well. Was getting blue smoke on start up, indicative of leaking valve stem oil seals allowing oil to seep into the cylinders. This product has put a stop to that and has improved cold running too. I think people have been asking to much of this product reading some reviews. This stuff will mainly help with blue smoke which is oil being burnt in the cylinders due to leaking vale stem seals or worn piston rings. If you are getting lots of blue smoke especially when the engine is warm when accelerating and cruising then its probably to far gone for this product. Its also not going to be much use for black smoke or white smoke as these are fuel/air related problems. This stuff is also in a purple colored can now when you are looking for it on the shelf!

    Rated 5 out of 5 by from It works but don't expect instant results My 09 plate zafira had developed a serious oil burning issue. After a oil and filter change the situation hasn't really improved, great clouds of oily smoke would appear form the exhaust under load. I tried this, first warming the bottle. It's taken almost a week and 50 miles or so to start working. There is still a small amount of smoke at a cold start but no more James Bind style smoke screens. Off course this product just thickens the vicousity of your oil and makes it more difficult to seep past stem seals and piston rings. It's a short term fix really, eventually a top end engine build may be required. However for the price it can't be beaten. Just a final point, - it's a good idea to run your engine or go for a drive after you've added this, it's so thick it may else just go into the sump and not get pumped around.

    Rated 5 out of 5 by from Useful if used in context Having read in many reviews about this product, I thought I would try it to confirm my suspicions about my stem seals failing. Contrary to what many people think, there is no miracle cure for a failed engine component in a bottle, at best you contain the concern but a failed gasket is still a failed gasket and a failed seal is still a failed seal, I tried a bottle of this and within 40 miles, noticed a marked and visible reduction of smoke from the exhaust on load and hills and after about 100 miles, no smoke out of the pipe, even on a cold start up, so yes, highly recommended and now I know the seals need doing, for six quid, certainly cheaper and faster than the plethora of checks that would have do be done otherwise to prove this out, word of advice, heat this up before putting it into the engine, it is thick, i mean seriously thick, about half an hour in just off boiling water did the trick but still took ten minutes to decant fully so make sure you have a cuppa ready....
