Assalam o Alaykum Brothers,
I’m seeking advice regarding my car's performance and an upcoming oil change. I’ve been using my car since 2013, which has now clocked over 250,000 km. Lately, I’ve noticed a significant drop in fuel efficiency — I’m getting around 9 km/l with the AC on, and about 11–12 km/l when the AC is off. The car also feels noticeably sluggish when the AC is running.
Additionally, there’s another issue that’s becoming a concern: when the car is idling in traffic, the AC stops cooling completely.
Given the age and mileage of the car, I suspect the oil and perhaps other components may need attention. I’d appreciate any recommendations regarding:
The most suitable engine oil for high-mileage vehicles
Possible reasons for the AC issue in traffic
Any other maintenance tips that might help improve performance and fuel economy
Looking forward to your expert guidance.
JazakAllah Khair.
