Great pre MOT
Used this product all the time prior taking my older Audi A3 for the MOT really helped. Used again as a precaution for my 2007 Z4 a couple of weeks ago and no issues at all with emissions I will continue to use every couple of months.

Done the job

Not sure if it made a difference or not
So this was a bit of an experiment use, car had only done about 30k but needed to go through a IVA test and I had some emission issues on a imported car (Lamba reading were to lean) it turned out it was a setting in the computer that made it a straight pipe in sports mode running lean) this didn't make any difference on the next test so can't really comment if it works or not but certainly didn't cause any issue hence the 5 stars

What another MOT .
My car as never burnt any oil, never ever topped up and it's a Y reg - clock mileage 65000 ish.Y reg. = 23 years old, I do about 600/700 miles a year. Far less emissions than 12000/15000 miles a year in a environment friendly car.Retired so I don't need a another new/second hand car.This is the second time I've used this stuff and the MOT was no problem.I don't think my car is any more smokey than before, I believe the government keep moving the goal post on smoke emissions, so people are forced to get rid of safe ( environment friendly) usable vehicles.
