Ecoteck power boost foam.......

[SAD VR6]

At the weekend used the foam on my VR6 to try an solve coughing and spluttering, as ive tried everything else, Relays etc......
No real change on the poor running but fuel cons has gone up on a good steady run from 31ish to at times yesterday 33......................mpg

Cancelled second mortage, might have enough change to buy a sandwich at next fuel stop

[SAD VR6]

my MPG must be wrong , i had it @60mph yesterday for a good while and mpg went to 35!!!!!!!!!!!
Went back to normal driving last night but still up at 32.4mpg
Any one else tried it in their Vr,s
