does your car consume oil too?
If yes, move to a thicker oil. and how much mileage it has done on odo?
After 100k or around it, this car starts consuming oil.
Besides, have you got plugs serviced or changed? if serviced, get them changed.
Also, does your car jerk when moving? or doesn't accelerate good enough? Silencer has carbon in it?
If yes, get the CAT Converter cleaned. Do not ever get it removed or it will cause O2 sensor faults.
Either get it cleaned or get a kabuli one.
All the best and do update.
