Tried it on my recently bought civic 1.5 T, 2016 model, 56000 km driven.
With apologies to nay sayers
, it actually worked.
Starting vibration reduced. Mileage went up from 7.5 to 9.0 km/L (city driving).
Throttle responds quicker. Car used to have two stage acceleration. I thought it was just turbo lag. But after using the cleaner, just one amazingly smooth accelertion.
Bottom line: for 800 rupees
, totally recommend it.
PS, dont know about long time affects. Will let you know after a couple of months
