Well said for a grumpy old man. At 4000 the fun is just beginning. (Oops sorry this is an SC thread)

Thats an easy one ..BTW i calced at at about 17.5 US . so we are pretty close.
The gas up thing is easy , you have to fold the hose over and rotate the nozle 180 degrees from what you would normally do . Then you can let it rip wide open. be carefull though because when it is full it will spit back

I don't keep track but I don't think I get more than 10.

WHAT?! 4000 RPM?! The fun just BEGINS at 4000 rpm!

Just one 911 owner's opinion here, but these cars were designed and built, not just to drive, to be "DRIVEN", which is to say driven in a manner that causes driver exhilaration over the awesome capabilities these cars can exhibit when their potential is exploited skillfully.

The furthest thing I'm inclined to do when I drop into my 911's seat is to go out and drive it "very gently".

This is not to say that I ever drive my 911 "roughly"! The key word here, I believe, is "smoothly", which is how ALL machinery, not just 911s, should be operated.

That said, a 911 can be driven "gently", and to truely drive it gently it MUST be driven smoothly, or it can be driven agressively, which CAN be done roughly, which, not to put it gently, is stupid. Driven agressively and smoothly, the 911 is in its element and shines.

I believe the 911 was designed to be driven "spiritedly" ("agressively" can have a negative connotation, i.e., percieved as symptomatic of road rage).

There's a world of difference between taking one's 911 for "a gentle drive over miles of winding country roads" and taking one's 911 for "a spirited drive over miles of winding roads".
The former can be done with any car. The latter is where the 911 excels - and, if done smoothly, is not the least bit detrimental to the car; again, the 911 was designed to be driven that way.

My 82 SC RoW coupe is about to turn 200,000 miles without a rebuild, burns no oil betweem 5000 mi oil changes and I take it to red-line in one gear or another every time I drive it, which is nearly daily.

Gently? Under 4000 rpm? HA!
Oh I definitely agree with all you said here about the car's "desire" to be driven harder. The other day I did actually take it for a nice little spin on a curvy mountain road here. I just try to 'baby' the car a bit because it's very low miles and in great shape. I see this particular one as sort of an 'investment'. Later on I plan on buying another SC, most likely backdating it to look like a longhood, putting an obnoxiously loud exhaust on it, and driving the pee out of it until it dies. Then I'll rebuild it, and do it all again. But this particular car I want to keep as pristine as possible. Now with that said, I did give into temptation the other day on an empty highway and touched 110 for a brief second.

Armon - I think your gas mileage is fine, esp. with our E10 gas. My 85 Row cab gets @ 18-19 mpg combined. The 79 turbo gets 13 mpg and the 86 turbo gets 10 mpg.

I had a Euro '78 SC and an '80 SC. I did not see any difference in gas mileage with them. Both were in the low 20's mpg. Both got better mileage than my '68 with the webers, which was in the 17-18 mpg range.

Using this method mine fuels up full with no issues at all. You do need to be careful and hold the gas line with your other hand so it doesn't hit your fender and leave a mark.

Joseph,

Thanks for that suggestion. I haven't tried it, but I'll do just that this morning!

Now that's two of you with this handy tip. I shoulda posted a question about this last summer when I got the car!!! Gassing my car up for 45 minutes, squeeze, click, squeeze, click, squeeze, click, curse curse curse....

Drive spiritedly, but fuel gently!

Hey, in deference to Iceman, when I rotate the gas pump 180 degrees...I'll do it counter clockwise!

That's a good point, I wasn't considering the E10 gas. I recently started using only Chevron because it's one of the cleaner gases (more detergents), I doubt it'll help my gas mileage but at least I feel better about using good gas.

13 and 10MPG, eh? Makes me glad mine isn't turbocharged!!!

Wait a minute. Scratch that. I still want a 930

But due to my love of Porsches and the high gas prices, my next one will most likely be an old 911T. Unless of course, I find another SC for a great price, but even then I'll back date it. I love the longhoods.

From your avatar it looks like you know the short way around the track.

Yep, more than you know. I thought you were talking HWY mileage. Seventeen for city is plenty normal. And to get 25mpg on the HWY, probably means you're running under 80mph.

... in 5th!

My last tank gave me 21 miles to the US gallon (usually I calculate in Imp. Gal). Not too bad. That is, if my tank was actually full. I'll compute again next tank.


Quick Reply: 78 SC... 17mpg???
