Do engine cleaners actually work??

[Hatchet Harry]

deffo... i agree...

[GTI EDITION (aka LTD)]

I stopped using optimax but 91 ron made the car even slower and moody and dropped me to 29 mpg instead of 41 with the optimax on a good run as for engine cleaners i stick a bottle of slick 50 in the car before the mot as it kills the emmissions for the test but its worth running a bottle through every 3000 miles or so..

The thought of a 'MOODY CAR'  ( Know what you mean )   Does anyone else's car suffer with 'OFF- DAYS', some times for no apparent reason ? ,I know mine does

mine did until i fixed all the vacuum leaks it had...  5 in total.. took about 8 months to find all of them!


it would be wheezy in hot weather.. best in the cold.. etc etc.. 

now its the same no matter what
