    Rated 4 out of 5 by from Quieter smoother more power and better starting After a recent oil change (gulf 5w30 long life oil) my 2004 merc s320CDi was loud, tappy, underpowered and very grindy and slow on startup. Was about to order Molyslip again but saw this for a fiver, read the reviews and bought 2 cans. Should have followed the advice of another review saying to heat up in hot water first! I tried pouring in 5c temp outside and it was like Vaseline. Had to use a shaft as a plunger to get it down the funnel. Once it was all in I noticed the difference after a few miles. The engine was quieter, more powerful, smoother and even the starter motor turns over faster. Also before it was raucous above 2000rpm but now silky smooth. Says one can for 4-6 litres of oil, my merc uses 8.5 litres and it still shows a difference, no need to add second can yet. Would highly recommend.

    Rated 5 out of 5 by from Quite surprised it actually worked I have a 27 year old weekend toy that I like to tinker with. At high RPM it can burn oil, and the rocker arms and tappets can be a bit chattery. I knew this product has been around for years so I thought I'd give it a try. And to my surprise, it actually really helped with the problem. No additive is going to fix a worn engine 100%, but my car does now burn much less oil when 'gunning it', and the cylinder head is much quieter - especially at idle. I do recommend warming up the can in some hot water first though, as the liquid is quite thick, like syrup.

    Rated 5 out of 5 by from Surprisingly, it actually works Had a tappety Toyota Aygo. Didn't want to sort the tappets as with this engine they need complete replacement. tried this in the vain hope that it would work, and yes its very effective. Has significantly quietened my engine. for £7 a tin it is very effective. As others have said it is very thick, has the consistency of golden syrup.

    Rated 5 out of 5 by from It works I've been using this for many year and I put them in all my oil changes. So far all these years I've never had any engine or emissions problems. So far so good. It does make the engine work a lot smoother. You don't need to use it on a fairly new car. I would recommend it. Besides, it doesn't cost much to use it at every servicing.

    Rated 4 out of 5 by from It does improve oil pressure at temperature I have an oil pressure problem when hot on a newly rebuilt motorcycle engine and I tried this as a stop gap before a second rebuild. It does work and is helping to mask the problem with my engine. I now have enough oil pressure to test out the engine to identify the cause.

    Rated 5 out of 5 by from Quietens a diesel engine 2.2 Diesel Honda Accord - Engine sounded like a taxi (noisy tappetts/lifters) despite fresh oil and filter. A whole can of Wynn's oil treatment (it is very viscous) was added to the engine alongside the oil change and after about 100 miles the engine sounds much smoother - for my case the difference in noise was pronounced.
