Your MPG and Radio Question - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I average about 22mpg mostly city, and can get up to 31mpg on highway.

Here's my tips on attaining higher fuel economy. I learned a lot of this when I owned a Honda Insight. That car will tell you what works and what doesn't as far as getting better gas mileage, and it all translates to other cars.

Use the correct grade gasoline. Your engine will run best on what the manufacturer recommends. Do not use higher or lower grade gasoline.
Make sure your tires are properly inflated. You can usually safely run them at a slightly higher pressure, which will reduce 'rolling resistance'. I would not recommend more than a couple PSI over the vehicle's suggested pressure
Have your alignment checked and adjusted. If you do not track your car, you could have the camber and toe adjusted to be more neutral.
Replace your air filter and change your oil at regular intervals
Avoid jackrabbit starts, and use the highest gear you can to cruise in. Avoid changing speed a lot on highways and freeways. Use your cruise control if you can.

So are you saying to cruise at around 3000rpm, and not smoke everyone on a green light.

Yep... something like that...

I average 19 MPG. I have not taken any long highway trips yet.

The peeling buttons on the radio can be fixed by Becker. I don't know the web site off hand, but you can just search for Becker USA and you should find it. You need to mail the radio to their facility in New Jersey. I checked into it, and it will be around $55 not including shipping costs. I may have mine done this summer while I'm on vacation. I just haven't decided if it annoys me enough to spend the money.

I find my Boxster (2000 2.7L) does very well on the highway - between 28 and 30 mpg. Howver, if I drive it hard or experince a lot of stop and go traffic the mileage is in the low 20's.

Thanks, I will give becker a call. I was just wondering if there is a cheap DIY fix, for peeling radio buttons, $55 + shiping for that is a bit pricey.

Around 19-20 for pure in-town driving and about 26-28 for highway. Keep in mind that I'm in Colorado and mileage suffers at altitude...

+1 on the starts. You can get pretty good in-town mileage if you're willing to give up the 4000 RPM sound.

My memory is failing. Here's a post from someone who had the job done. The cost is closer to $90!

I knew there was a reason I was thinking of living with the problem. A DIY solution would be welcome.
