New Civic mileage -- update

Reviving an old thread that I couldn't locate anymore:

06 Civic now at around 3,000 miles -- last two tanks, almost 35 and
almost 37 mpg respectively. Up from about 29 when it was new.

I'm sure the switch to summer fuel made a substantial difference. It
always added about 10% to the mileage of my last VW, an '85 Scirocco.

 

That's encouraging. I have getting from 38-42 on an 03 LX 5 spd on the
road.

 

In my case, during the winter months, I can get 550km from a tank of
gas, while in the summer months, my fuel consumption willl improve to
650km per tank. The fact that I switch from winter tires to light
weight summer wheels probably contributes to the improvments. I haven't
pinned down which factors which have the greatest impact on fuel
consumption. being, summer/winter gas, light weight - low rolling
resistance wheels, quicker warm up and better/densar oxigen rich air.
Whatever the reason, I'm going to bank with the extra 100km/tank.

My 2001 Civic EX is at 190,000 miles (I commute 110 miles R/T daily)
and I get
39-40 mpg on the I'state (70 mph ) with ease. I replaced the platinum
plugs at 175K miles (although I should have done it sooner), and just
had the timing belt/water pump replaced two weeks ago. Oil change every
3 months is a must for me: Castrol GTX 5w-20. No oil usage to speak of
between changes.

When I took the car to the dealer for the timing belt work, the service
manager stated that they had no record of me being in for service since
the date of sale (12/30/00). I said : "That's right..I haven't been
back since the day I bought it. "

It runs GREAT, why should I ? I LOVE this car.

 

The engine will be more efficient running in cold air...

But it'll be the warm up time in conjunction with the difference in tyres
that will make the biggest difference.

Please excuse me, I'm new to Honda, been a Toyata truck fan all my life.
What is "summer fuel" and how is it any different than what you purchase at
the pump?

I didn't know where were winter/summer tires, either. What is the
difference between the two?


Thanks,

Summer fuel is the stuff the refineries produce and distribute from late
spring to early fall. It has lower "light end" content and is less volatile
than winter fuel.

If your ambient temperature is much the same year-round (Hawaii), you'll
get the same gas all year. If you live where I do (120 degree spread
between min and max) you get very different gas at different points in the
year.

Winter tires are made of a softer compound and have a slightly different
tread pattern in order to maximize grip at very cold temeratures and on
ice. Then you have SNOW tires, which are similar to winter tires, but more
intended for traction in deep snow.

Again, if you live in an area with year-round temperatures that are always
comfortably above freezing, you don't need anything but summer tires.
