Honda Civic 1.8 litre VTi seven position automatic sedan 2007
No known modifications
I've just bought a second-hand Honda Civic with a i-VTEC engine. The previous owner was a lady who played golf as I found a golf tee in the boot, er, trunk. The car has 133km on the clock and has been well maintained. (About every 5,000km). I have the service books to prove it. Anyways, I just did an economy test for 'around town' driving and it's getting 12.8 l/100km or 22mpg. The combined fuel consumption for this vehicle is 7.2 l/100km which translates to 39mpg. Being Australian, I use imperial gallons in my calculations. I think that the 'around town' figure should be about 33mpg. Now, what do I do about it, I asks myself. I thought, maybe I should give it some 'rough' treatment - take it for a thrashing on the highway for a couple of hours to burn off carbon deposits around the spark plugs and injectors. Or I could put an additive in the fuel tank and again, give it a hiding as mentioned above. Another thing that might be the problem is that the MAP and throttle body need cleaning. (Never done this before, but have seen it done on Youtube for another car I owned but never got around to doing it. I still have the unused pressure cans for that job.) And I read someplace about replacing the O2 sensor. What would you do and in what order, is my question?
