Santro Club GV, Model 2005. No engine work done so for.
Engine start knocking on patrol. done tuning many times from dift machenic also scanner chk... Used high octane on mechanic's advice but during high octain & CNG use, no knocking but when refuelled with super again, that knocking start again
mostly knocking appears in 2nd, 3rd and 4th gears in low rpm.
it sounds like ترڑ ترڑ ترڑ ترڑ ترڑ ترڑ ترڑ ترڑ*
What would be the remedy for this to permanently solve this knocking problem
