Dheera manana roara da detailed reply da para, aoo da kho da pekhawar ke har qisma mechanics shta, za kho "Abid" la tale wom warsak road sara che de near suzuki.
Yes i know my car requires some work but that mechanic tensed me alot by saying that engine is finished so thats why i asked here, and also i wanted to know if its worth spending money on these tasks or will it be of no use if the engine is weak.
i wll try to find some good mechanic now, also if you or others know someone good for this work in idsi, kindly let me know.
Also recommend which exact oil should I use in this situation, (the previous one said he changed to Zic few days before, i m thinking about havouline 20w-50 or shell).
