really? I overdo it a lot then? I do it every 30 to 45 days...
I do feel that pick and acceleration gets 19/20 better.. idle become better etc.. and the "ghutton" in suddenly pressing the accelerator goes away...
just yesterday I did it again, found a Chinese can at hyperstar 550ml for 230 rupees (I thought its not a bad deal since STP is rs. 360 for 440ml)
Sprayed the whole can in the throat in one go at 2500-3500 RPM range..and then drove the car around few blocks.
