I just did the math on my 993... 28 mpg mixed city/highway! I've been driving it pretty gently this last tankful as I learn the best shift points and clutch engagement, but there were a few Italian tuneups in there.

WOW! My Accord never got 28.

These cars are really something extra!

 

Thaddeus,

There is a simple cure for that... get a turbo!

 

I took our 5 BMW 530I on a 600 mile trip. We got 31.4 MPG.

 

Thats great. What's your secret? For me 20mpg is good.

 

When I first got my car, I calculated the mileage. It was greater than our other two cars. That was sufficient basis for me to tell my wife, "The 993 is the most fuel efficient car we own." I see no need in recalculating now that I find myself enjoying the whine of the engine in the 4000+ RPM range more and more.

I use the same theory when it comes to testing my cholesterol--it was great the last time I had it tested. (3 years ago....)

 

I'm getting mid 20's with city/highway mix. Varies a bit depending on weather, amount of standing rain on highways, stop and go.. etc. etc. Yeah.. I'm pleasantly surprised at the milage.

 

I consistently get:

993 - 18 mpg
996 - 22 mpg

I drive both car fairly hard after warm up whenever LA traffic permits.

 

wow, I must be doing something wrong.
Best I can get with the 3 is 9 miles to the gallon?????

 

Wow......you must roll down hills with the engine off, get tow off all the big trucks on the highway, must have lightened the car by throwing everything except seat and steering wheel away, must get to a cruising speed, never brake.......etc........I once tried very hard to see what I could get on 10 gals.....did it three times......and yes I know the gauges are not accurate.......but I was not far out...filled take to top (overflowing) each time.........it varied a little but not much........anyway the best I got driving very carefully was 23mpg............on average I am 18-20mpg........dont tell my wife!!! She thinks SUVs that do 15ish should not be on the road...!!!

 

28? Wow! Did you check your math?

The first time I checked my mileage, I got 13.6mpg. That was daily driving, zero freeway, very heavy stop & go traffic in January rains. More often, I get between 15 and 19 mpg. I must get well above 20 on the freeway, because if I have even a couple of hours of freeway driving on a tank, my mileage is 2-3 mpg better than with no freeway.

As far as driving style goes, I did an experiment. On one tank, I drove as gently as I could, stayed within the speed limit, etc., trying to squeeze every mile out of each gallon. I got 17.2mpg. The next tank, I let it rip. I got 16.6mpg. This was driving the same route, no real freeway driving.

 

On board computer says 19.8 - to 20.x at each fill-up. I drive mine to work every day, half surface streets and half freeways.

I'm convinced that the number of warm-ups per tank of gas has more effect on mileage than the type of driving I do. That rich-running startup in the mornings kills my mileage. If I drive longer trips on weekends, I get 22 or so even though I drive more aggressively than I do on my commutes.

 

FWIW. The exact same vehicle on the same day, ridden (it was a motorcycle) from WA to CA, in CA my gas milage really dropped, a lot. More than 10%. It was shocking. Bike even ran a little worse. Bought gas at Shell and Chevron all the way down. After my first tank in OR it went back up again. If you guys had decent gas down there, image the better mileage!

PS. When I drove my 964 to OR,CA,NV and back.. same thing but I was not tracking mileage on that trip.. but the car certainly ran better once the last tank of that pig-**** they call gas in CA was run out. What in the world is in the addative packages that does that down there!?

 

I got high 20s when I drove my car down from its former home in NH to VA. With my wife & 2 kids aboard I drove sensibly and it was almost all highway.

I haven't seen over about 22mpg since then :-)

 

My drive to work is about 4.5 miles, and I generally only stop 2ce... I haven't been doing anything special except focussing on shift points and such because the dictates of my OCD require me to shift more smoothly than an automatic can do it, whether driving slowly or fast (while disengaging/engaging the clutch rapidly). So there's not a lot of time spent idling at stops, doubtless that has a lot to do with my mileage numbers.

My 928 only got about 16 on the same route, and that was in good tune too....

 

Thaddeus,

4.5 miles is barely enuff to get the oil up to temps... making your high mileage even more remarkable. Rufus gets about 13.5 around town, 21 on the highway, if you can keep it under 140 mph.
