ZX1EXTRALUBE MICRO OIL METAL TREATMENT 250ml

I apparently made a mistake in not observing absolute cleanliness when changing the oil filter on my Astra 1.7 cdti Diesel (I didn't clean all of the chalk dust / talc off of the o ring kit that comes with the filter (why do they put what appears to be abrasive matter in an oil filter kit anway?) - I was in a terrible mood at the time and hence I rushed the job). Also the design of the oil filter housing position couldn't be worse since it faces upwards to catch any dirt that may fall off the bonnet while you have it disassembled unlike on old Austin / Morris cars that had the housing facing downwards. Anyway quite soon after the oil / filter change I noticed that the engine sounded worse and it seemed that the oil pressure was low since I had to run the engine at a fast idle for 4 - 5 minutes before driving off otherwise you could really hear a rattling noise.So I felt forced to put an additive in to quieten down the engine. I first thought of Molyslip which I'd had good experience with in the past in the old classic Mini with its combined engine / gearbox set up - you could really feel that changing gear became less obstructive - but was put off due to turbo engines not being mentioned on the can so I tried ZX1.I can honestly say that it has quietened down the engine noise and I feel has saved my engine (and improved the fuel consumption too).I put a little ZX1 in the engine every oil change btw that they don't recommend in the instructions but if you write to them they're very helpful and they said that some people in their organisation put 25 ml in every oil change, some people 50 ml & some 100 ml; he recommended I try 50 ml every oil change.I have noticed with my worn engine that if you drive too fast it is possible to wear away the ZX1 protective coating and the engine becomes noisey again; I find that keeping the revs to no more than 2750 RPM keeps the ZX1 film intact which is nearly an indicated 80 MPH for my car so not too bad really.

Well, the product was delivered as expected. It has taken me a while to get around to doing a oil change, but yesterday I did and added the XT1. I have a Toyota RAV4 Mk 2 with 120k on. They are renowned for sounding like a tractor particularly from cold.Started up engine and can't say I noticed any difference. However after a few minutes at tick over whilst I topped tyre pressures up, I noticed the engine to be running much quieter. I mean quieter than usual after warm up. Took for test run and could tell the difference.This morning I took my wife and son to work and the both could feel and hear the difference. Everything is quieter, smoother (like someone put silk in the engine) and seems much more power.I am off tomorrow for a long weekend in Derbyshire and will clock up quite a few miles so will report findings on fuel consumption. I normally average 9 to 9.5 mpl on runs like this which I keep getting check on with a scangauge 2, so will see any change immediately.I have tried various oil additives over lots of years and have been happy with most, so far this is the only one I would give 5 stars to. Will it keep all 5?

I’ve been using super-slippery ZX1 Extralube for over 20 years without issue. Quietens noisy engines and reduces fuel consumption by 2-4mpg. Better cold starting, and improved engine response. Used in every car I’ve owned. Apply every 25,000 miles for maximum protection. It’s not an oil additive, it’s a metal treatment, as it chemically bonds the the metal.My day job involves Tribology, so I appreciate how this works. It is not snake oil.I’ve also used their other products, and their pin-oiler is a must for any workshop.

Very pleased with the difference in sound and smoothness of the engine. And hopefully more protection against wear on the engine.Would highly recommend

I used ZX1 on my 93 Honda CB1000 Super Four after seeing Allen Millyard (garden shed engineering genius) recommend it. The engine was already pretty smooth but it was noticeable how it quietened down further and reduced high frequency vibrations. The only problem was it caused huge clutch slip the next time I rode the bike (oil filler is directly over the clutch) and it took about 150 miles of riding over 3 trips before it went away. Clutch is fine again but it is something to be aware of. Next time I'll introduce the ZX1 in several small doses over a period of days rather than in just one. Cant comment on fuel consumption because I don't track it but it certainly made a smooth engine even smoother.

One of the best on the market but expensive

this is the best oil additive, in my opinion, i ran a diesel Hyundai Tucson for 12 years and i replaced the ZX1 ever 12 months with its service [always used fully synthetic oil too 05/30 ] my lovely Tucson never let me down and as i have just sold it i hope the new owner has as much joy with it as i did .my replacement Tucson [on order ] will also be having the ZX1 treatment the replacement will be a petrol as this product is suitable for both engines i have been using ZX1 for many years its the only additive to receive NATO approval my new Tucson has arrived and the first thing i did whilst still at the dealership was pour the whole bottle into the oil filler hole .its the best additive because it works on a molecular level unlike ANY other additive it will last around 3 oil changes i replenish the XZ1 with every oil change i also have it in the gearbox and window washer bottle as its a molecular product it sticks to the moving parts protecting them ..in my old Tucson 4x4 i used it in the transfer box and the rear differential too .i used it pretty much where there is going to be wear metal on metal DO NOT USE IT IN YOUR BRAKE SYSTEM

i have used zx 1 oil in past the result was great. oil pump was making noise in morning used zx 1 oil went quiteanother car injector pump starting quite diesel got good milage
