How to get better gas mileage.
Hey can anyone give me some tips on getting better gas mileage. And does it use less gas when you coast to a stop, or when you downshift? Right now I get about 15 mpg, it seems to fluctuate sometimes though. Can I expect anything better than that?

When you coast the engine goes back to idle and uses gas, but there is no fuel for decel so downshift. Also, if your n/a go unplug your secondary injectors never get above 3800 rpms but thats the point lol

**** low, go slow, and do routine maintance, those three things are the key to good gas milage. I cost to a stop. Clutch in drops to idle and try to keep rolling forward at lest 5MPH or more that way you dont have to start going from a full stop.

Push the thing! What do you want, a civic? Drive the beast or sell it! Just my opinion, I just paid 3.09 today for gas, and I just got fired! **** it, other jobs, not cars!

I just recently got the best mileage ever in my 90 GTU. 17.6mpg and I had an exhaust leak. Just shift at 3k and drive in 5th alot. Engine brake as much as possible. Get a tune up and get an SAFC that should help a little too.

Timing will make a huge difference too. I checked my timing on the S4 n/a which was a little too backed off. I advanced it to just a hair past stock, and im getting 20 mpg in mixed hwy/city driving, about 2-3 mpg better than before. this is with full exhaust, no emissions, premixing, and 5th/6th ports wired open.
btw, I drove a tank with 5th/6th ports wired closed and only noticed a 1 mpg improvement

The optimal MGP on an FC is at 90MPH and 3,500RPM drive like that and you should get a little better MPG mauch out for the po though...

yeah an MSD ignition will help the longer spark will allow the gas in the chamber to combust more efficiently so you will get all the power out of the gas you put in instead of some being wasted into the exhaust...

My 91 Turbo at 70mph is 3 grand, my 88 Vert is about 2.7 ~ 2.8 grand at 70mph....rear-end gearing difference. I still think you need to do the basic stuff, tune up and all first. Then watch how you drive.

make sure TPS is in adjustment/good. if i drive the car hard it will still get at least 22 at fill up. its never dipped below that. my engine also has good compression, so an older engine will probably get worse mileage. i think a good compression engine, and a good running engine is the most vital part of gas mileage. also my car weighs in the 2500's so that could make a difference.
