Guys I recently got my City's ('09 A/T) fuel pump replaced. Mileage is not going 8kms/ltr upwards.
Before it was 10-11kms/ltr.
I got all fluids along with oil and filters changed, 4months ago.
1- After the fuel pump replacement, do I need to take my car to Honda for an electric tune-up etc?
2- I really dont think that changing fluids/filters would solve the problem but I'll give it a shot again. Please recommend a 'specific' brand and variant of engine oil for my car
3- Is there a possibility that the spark plugs that I got replaced last time were faulty? (As a mechanic bought it for me, so I am not too sure if they were not already used ones or refurbished). Please recommend 'specific brand of plugs and the variant'
4- I have a very hot girlfriend, is there a possibility that the engine gets very hot too when she sits my car and eventually burning more fuel than average?
