Extralube ZX1 Micro Oil Metal Treatment 1 Litre - The Ultimate Friction Eliminator

I've pored over as many forums as I can find, and while results vary for users I've yet to find a "this broke X" review. Based on this less than scientific research (because there is no scientific research available) I bought a litre. First it went into my 2004 216,000 mile Honda Insight engine oil. Within a few miles I heard a quieter engine. I've done 207,000 of those miles, so I know that car. A thousand miles later it went into my 2010 Kawasaki Z1000, and the gear shift became butter smooth (on motorbikes engine and clutch oil are often but not always shared). I've since changed the gearbox oil on the car and used this, and the worn synchro on 2nd has quietened (though I still double declutch as it's still worn). Overall low mileage using it but with significant apparent results, so it seems to be doing its job. I'll try to remember to come back and comment after a slightly longer test, but so far would recommend it.

Does what it says. In engine oil and upper cylinder lubricant. The car loves it

Excellent

It's working very well

all ok does what it says on the tin

Have used this product in 5 car's over the last 15 or so years. Mainly in the engine but also added to fuel gearbox and cooling systems were needed. Over the years I have observed that it makes improvements to fuel economy and make engines run quieter and smoother. Arrived well within date due and well packaged.

I purchased this for a friend who had been saying they had tried to find it for years with no success. Apparently it's marvellous and makes the running of the car smoother, even extending the life of the car by greatly reducing the engine's ongoing wear and tear. Not really my field of interest but my friend was over the moon with it.

Simply works. Used everywhere possible. Has a good effect in terms of noise everywhere. As noise is a sign of inefficiency (wasted energy) by this basis alone it works well.
