Mr A.W. M.Inst.MSM. : Northumberland

"... 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..."
