I have used ZX1 for years. I had an older Hymer Motorhome and wanted it 100% before setting off for Spain. I put this in the engine AND fuel and noticed a difference pretty soon. It seemed to be sharper off the starting-blocks, which is what you need when trying to keep up with modern traffic in a Camper. The engine seem to run a bit smoother, perhaps even more quietly - that part might be my imagination. I have used it in EVERY car I have bought since and find similar results. Unlike another well-known engine additive, it doesn't contain PTFE which over time becomes a 'gunk.' This bonds to the metal without any residue. See the web-site for more info. I know it's expensive compared to other products, which puts friends off buying it when I recommend it, but it does such a good job. The engine is the heart of any vehicle, once it gets into trouble or stops it is frustrating. I know when I put this stuff in the engine and fuel, that as long as I change the oil, filters etc, it will help prolong the engine and ensure it is functioning at its best. I'm not a mechanic, but I think to myself,"As long as you do the best that you can for the engine - the longer it will last and the more efficient it will be."Read full review

Very good product, Many engine manufacturers advise not to use an oil additive. ZX1 is not an additive, it bonds to the metal parts that need to be treated for eliminating friction. Better than Slik 50. Have ordered another 2. Have a generator and 2 stroke brush cutters,chainsaws, Mowers i need to use it on. Works on virtually anything with moving parts.

I've used this for many years now. It's not cheap but it lasts a long time, as it only needs to be used in small amounts. It claims to be a friction eliminator and I believe it. Many years ago, I accidently spilt a drop of this oil onto the inside of a bucket. The drop hit the inside slope of the bucket and bounced off it! I was amazed. Any other oil would hit the inside and stick to it, then run down the side of the bucket. But not ZX1. It bounced off, showing me just how fine and low friction this stuff is. I was happy using it in all my racing kart engines & wheel bearings after that. Nowadays I put a small drop in with the engine oil in all my garden machinery to protect the engine, & occasionally in with the petrol, to help protect the carb. Compared with 'usual' engine oil, I believe this can really get into the tiny nooks and crannies and keep the engine running smoother. Read full review
