"Having used your ZX1 products now since early this year I felt I had to write to congratulate you on the performance of these products which have exceeded my expectations.... Since putting ZX1 Extralube in my BMW 325i the engine performance has noticeably improved with very prompt starting and smoother running. The most noticeable effect has been with petrol consumption, increasing from approximately 240 miles per tank to consistently over 300 miles per tank of urban driving."

"... can report that having done about 5,000 miles in the Jaguar and 7,000 miles in the Rover, (both cars are now in their 8th year, being 1990's on 'G' plates) are running beautifully, the engines being noticeably "smoother" especially on cold starts in the current freezing temperatures, and the M.P.G. of the Rover has improved by about 4 mpg from the previous 31 / 32 mpg to around 35 / 36 and this all on local running..."

"I purchased a 250ml bottle of Extralube ZX1... administered the liquid to my 10 year old BMW 525E with 80,000 miles on the clock. The results were immediate and permanent thus far. It appears to do everything you claim, including and especially during the recent very cold weather, give excellent cold start protection. The fact that prior to using ZX1 my fuel consumption had fallen to around 27 mpg and has now returned to 30 + mpg speaks volumes. All this I might add before the cars been tuned !."
