certain amount of engine reduction is normal I guess and even mentioned in the manual of cars.
change asap to the thinnest oil recommended by the owner`s manual. Dont listen to any "expert" here or any mechanic
Use PSO oil nd fuel, support Pakistan
A certain amount is fine, but I was talking about a noticeable consumption like 500 ml or so.However, thinnest oil is NOT always recommended, it all depends on the health of the engine of your car.
Thank you for correction "Caltex is under Chevron Pakistan flag"
500 ml after 5000 km is normal. Even 1000ml is also normal.
