Acura Integra Owner Wants Better MPG

I drive a 1990 Acura Integra GS with a B20B 2.0L high compression Japanese domestic market CR-V engine in it.

Here is some information about my car:
Current Mileage: 127,248 and halfway between 1-2/10ths*
Original estimated EPA Fuel Mileage for 1990 Acura Integra GS (5-speed)** 24/28/25 mpg (City/Highway/Combined)
Revised estimated EPA Fuel Mileage for 1990 Acura Integra GS (5-speed)** 21/26/23 (City/Highway/Combined)
Fuel Capacity: 13.2 gallons

*Chassis mileage, the engine has approximately 70,000-80,000 miles on it.
**This is the listed EPA fuel mileage for a stock 1990 Acura Integra GS five-speed with a 1.8L B18A1. Please note that my Integra has had the stock engine swapped for a high compression JDM B20B.

I joined an Insight forum to find information about driving to save gas and Guillermo told me about this forum, which, since I don't drive an Insight, is better suited to my needs.

I look forward to learning a lot and hope to contribute a little now and then.

Sounds interesting. What ECU is running it? Is it converted to OBD1?

High compression will help your mpg but it may also require higher octane. It's a trade-off I'd be willing to make.

Agreed. VE is worth it

Yes, I believe it is converted to OBD1.

Well, I don't have any knocking, so it seems 87 octane is good for now.

How are you, SH? I talked to you a few times on H-T about stealth alarm installs.

Small world.

Well my DA has a bad tranny and I'm having a hard time working out some bugs with the Coil on plug conversion on my Civic.

I just moved and got a two car garage

But it's full of boxes and crap

Some day soon I hope to have a two car garage. One for my DD and one for my project car.

If I'm lucky, the DD will be a Honda Insight and the project car will be my DA.

Right now I have to borrow my parents garage whenever I want to work on anything, which is okay since they're in the same town I am but it's going to be a PITA when I swap out my blown stock struts for new ones in a few weeks.


Back on topic:
So far I've been driving using methods I've read about to conserve fuel on this tank alone. Soon I should be able to post what my average MPG was on this tank and then try to improve on that.

Now that I've found this forum, I have a lot of reading to do!

Heh, that happened to me too, went from a 1000 sq ft house with basement to 1400 sqft with same size basement and garage and somehow there's no room for anything and the garage is stuffed with crap.

Just a little update, I'm at half a tank, according to the gas gauge in my Integra and the trip meter is at 172.6 miles. The tank holds 13.2 gallons, so half is approximately 6.6 gallons.

172.6miles/6.6gallons=26.15mpg

This is just an estimate, of course, since I can't tell exactly how many gallons I've used until I fill up again but 26.15mpg is better than the revised highway EPA estimate and I have a 2.0L engine, rather than the stock 1.8L.

I'm pretty happy with this result but I'm by no means satisfied. I know I'm not doing everything I can do to conserve gas. Ultimately, I'd like to get 32mpg per tank.

I've found the biggest change for me is not actually changing the way I drive but changing the way I think. Thinking about driving efficiently, accelerating slowly, driving the speed limit... these things have sort of calmed down the way I drive. I'm not driving nearly as aggressively now that I'm concentrating on saving gas and I find myself less likely to engage in the "road-ragey" behavior I was more prone to in the past when I was zipping around like Speed Racer.

Here's a tip that actually seems to work: Start posting your gaslogs. When you're actively doing it where everyone can see, you're more liable to do what you said - think about your driving - and that alone will help increase a couple of MPG. Keep us posted!
