Knocking problem checked by Pak Suzuki technician yesterday and advised to change plugs as previous ones ran just 11000 km so for but as he said bad fuel causes this knocking problem. Though I was not fully satisifed by the answer, but ad per his advise changed the plugs to new one and feel better performance for pick and knocking as reduced to nill at least for now.
He also advised to use one full tank of high octain, will do so same after finishing existing patrol.
Hope all goes smooth afterwords, but one thing is for sure that plugs play a very important role in case of performance, pick and knocking reduction.
posting pics of previous genuine plugs which came with the car and ran just 11000 km, though 3s mechanic suggest these can be further used as these are not in that bad condition.
