2006 Nissan Sentra 6 cyl Front Wheel Drive Automatic 42,334 kilometers.

When I bought my car I opted for a 1300 engine for fuel efficiency. The Nissan salesman promised 12 km per liter city driving and 15 km/ltr on highway. The car is actually doing only 7-8 km per liter. Whenever I bring this up with the dealer's mechanics I am met only with a blank stare. The car is regularly maintained, tires properly inflated, etc. Is this the best mileage that I should be getting from this car? (My old 1992 Honda Civic hatchback still gives me 10 km per hour!)

Which country are you in? Fuel efficiency varies from country to country.

Your salesman may have just read you the brochure stating the 12/15 city/highway mileage.

Fuel efficiency is calculated to appeal consumer buying attitude. It is usually done with only the driver (skinny one), no passenger or cargo. Performed on a flat straightaway, speed of 50 mph (80kmh), no accessories (AC, radio, sometimes no power equipment, etc), usually with manual transmission. That is why many advertisements carry the tiny disclaimer to say that your fuel efficiency will vary between vehicles and driving habits.

So, any deviations from the manufacturer's testing will affect your fuel mileage. While 12kml (reflects to about 30 miles per US gallon) is not impossible, it is hard to achieve if the vehicle is equipped with many options, AC running most of the time, and so forth.

8kml (about 20 miles per US gallon) is a little low. I understand that the regular maintenance is performed but that statement varies from one person to another. To most people, maintenance is oil change. What is your definition of maintenance?

Is the car completely stock, or has been "performance enhanced". Larger wheels, lowering spring, among others will have adverse effect to fuel efficiency. At a little over 26K miles, I would try adding some fuel system cleaner into the fuel tank to clean up the fuel injectors, replacing air filter, PCV valve, fuel filter. You may also want to pull the spark plugs and see if they are still in good condition and are properly gapped.

To Mr. Zackman:

When a Nissan salesman speaks to me I assume that he represents the car manufacturer. So when he told me that the car would make 12-15 kms/lilter, it is as if Nissan itself made that representation.

As to what I mean by periodic maintenance, I follow the manufacturer's manual strictly; and the maintenance work is done by the Nissan service center itself.

Thank you.
