Default The honda dealer in santa monica, ca. said that you can drive n?

d3 up to 45 miles on the surface streets and that will save you at least 10% of gas. Has anyone ever heard of this? By the way I drive a 2001 civic

I've had older Civics (1974 and 1979) with stick shift, and they had tachometers too, and I found back then that changing gears from third to fourth at 45mph was ideal for them. I have also found that true of some other cars I've driven, such as VW Rabbits and Jettas, both diesel. So, I might agree with your dealer, IF your talking of standard transmission. If not, and considering my Civics were quite a bit older than yours and things may have been changed in the transmissions since then, you might want to get a more reliable or updated source than me, but I hope that gives you some background on your concern. Civics have always been good cars to me. Good to see you taking care of yours.

The dealer referring to D3 tells me you have an automatic transmission. I am not specifically familiar with the options on the transmission of a 2001 Civic but I know Hondas well.Improved gas mileage comes from putting lots of road under the car while the engine is running as slow as it can. That means being in as high a gear as available or overdrive. Your drive selector should offer you a D1, D2, D3, and D4. Sometimes they leave out the D for the 1 and 2. If you select 1 or D1 before moving, you will find the transmission never shifts out of low gear and the engine speed is fast while your rate of travel is slow. Shifting to 2 or D2 at that point gives you the next higher gear and you travel faster while the engine speed decreases (raises as you give it more gas with speed). Shifting to D3 adds yet a higher gear and you go faster while your engine speed decreases further (raises with more gas and speed). And then, finally, you get to the last selection... D4 which should be overdrive in Hondas and gives you the most rate of travel with the least engine speed. This should translate into the best mileage possible for your car. If your car only has D3 for it's highest gear, that's the one it should be in. All this should be spelled out in your owner's manual as well.One of the best things to do to improve gas mileage is to ensure your tires are inflated properly. The car manufacturer puts a recommended tire pressure on the door jamb on the driver's side. This is not a maximum rating for the tire, it's a value to give you optimum performance and ride quality. The maximum pressure you can inflate the tires to and still get even wear is stamped into the side of the tire itself. It is safe to exceed the door jamb specification as long as you don't exceed the maximum pressure listed on the tire. Ride quality will suffer a little bit as the tires will be firmer but I hardly notice it at all in my Hondas.My son's old Isuzu Amigo, the door jamb recommed 28 psi while the tires could go to 44 psi. That's quite a difference and made a huge difference at the gas pump.
