1975 911S mpg?

I'm going to get my 911 on the road next year, and was wondering what gas mileage do you get on a 1975 911S with a stock 2.7?

When I still had the stock 2.7 in my '76, I would routinely get low-to-mid 20s in mixed city driving and 27 or 28 on the interstate.

What Mike said. I drove my 911 home after my tour in the Navy. From San Diego to Ohio I got between 28 to 29 mpg...which was all highway of course.

Wow. That's better gas mileage than my jeep liberty, that's a great excuse to drive it every day.

Might be a bit less than that with today's ethanol-infused fuels, though. Still decent, however.

In the 20's, but who cares, you're driving a Porsche....
