When burnt, chlorinated paraffins produce corrosive hydrochloric acid, and organo-chlorine compounds including the highly poisonous phosgene gas. Apart from these corrosion and health hazards, with petrol engines the deactivation of exhaust catalysts is also a problem. No, we do not recommend this as the treatment is designed to mix with manual fluids. Unfortunately we no longer supply an Automatic Gearbox Treatment. Didn't notice much difference at first but after I had used the car for a couple of hours on a longer run, the tapping and clattering in the engine had considerably reduced to almost nothing. I was quite frankly amazed. Yes, the product has been used in many vehicles over many years with hydraulic tappets with no negative effects.

They all contain chlorinated paraffin ?exteme pressure?(EP) compounds first used in the 1930s in heavily-loaded industrial gearboxes, and in some automotive transmission applications, mainly hypoid gears.

Proprietary friction modifier creates enhanced layer of lubrication to minimize heat produced by friction in the engine It is touted as being "a super-suspension of micro-miniature PTFE particles and soluble Molybdenum, permanently suspended in oil." My car has a manual gearbox, but uses Automatic transmission fluid; can I use the Manual Gearbox Treatment? This enhanced semi-synthetic engine oil meets API SM/CF requirements to better ensure your oil change is NOT diluted.

I asked a chemist recently who had tested many of these products and this was the reply I recieved - scary stuff! How is it then, that adding something out of a can; on the basis of a large can for large engine, and small can for a small engine, and with no change in dosage if you have Sainsbury's cheapest or Mobil1 fully synthetic, possibly be a good idea? My own experience is that you should use a good oil (you cite fully synth) and change it according to HJs recommendations. As an example, my own car is a 97 Rover 820 Vitesse Sport. This is the later 200bhp version with 17 inch alloys and proper suspension, not the feeble original 180bhp Vitesse turbo. It is just a few dozen miles short of 130k now. I bought it from the previous owner with 88k up. like me he is a car nut and looks after his cars well. Also like me he's an ex-motorsport driver and drives "enthusiastically". The car has been run on Mobil 1 or GTX Magnatec under the previous owner and on Halfords FS by me. Believe me when I say this car is as clean inside the cam covers as the day it was bought new. It also drives like new - at a Revs sponsored event I managed 30-70 in 6.6 secs, 'book' is 6.8 secs!!! i run it on Tesco fuel all the time.

X-1R Friction Eliminator and its clones are based upon very outdated technology, which was abandoned by responsible lubricant manufacturers for automotive transmission uses in the 1950s. Chlorinated compounds still find applications in metal working, but their use is on the decline because of health and safety considerations. It helps to lubricate the power steering pump, reducing wear and friction. It is formulated to protect against power steering leeks and keeps seals in good condition, helping to prevent the need for repairs. Features & Benefits:
