Fuel consumption..
 

My volvo car is 2004 S80 2.0T model.
I replaced fuel filter and engine oil and filter 2 days ago.
But the fuel consumption have got higher than before.
Almost 15~16 liter/100kms.
The oil filter and fuel filter are all Bosch product.
Oil is the castrol magnatec 5W40.
What's wrong with my car?
Originally, It was 11~12 liters/100 kms.
Is it normal?
Thanks.

I solved the problem with checking the engine oil level.
Mechanic filled too much oil. -,,-
Oil was over F.
Now, the fuel consumption came back to 10.5 liters/100kms.
