TANK RANGE!! - Page 2 - Boxster/Cayman - PistonHeads UK

Hi Anyone got a ball park figure of what i could expect to achieve driving down to Italy,i will be doing a mixture of motorway/nationals, i have a 2006 3.2S, i did almost the same last year in my 2.7 cayman and managed 33pmg overall which is not bad.

You should get 300-350miles to a tank if you're just cruising on the motorway/main roads at a sensible speed. Start going nuts and it'll be more like 280

I drove from Preston to Essex and back on Monday - combination of motorway and the A14. Very busy so cruising anywhere between 60 abd 80 with lots of 50 average stuff. I got 415 miles and it was still showing 50 left when the bingo light came on. I know I drive like a wuss etc ........

If I recall correctly, I always estimate on a steady long distance drive to fill up every 4 hours of driving. (cayman s and boxster spyder). Though Spyder tank is a little bit smaller.

Figure 25mpg and if you fill up at 12 gallons (leaving 4+ gallons in the tank as "reserve") that is 300 miles per tank with enough fuel that you can be a bit picky where you fill up. But don't you have a working fuel level gage? And an OBC that can display remaining miles to fueling? With my Boxster (with no OBC) and my Turbo (with an OBC) when I'm on the road I just try to fill up when it is convenient -- easy off easy back the freeway/highway -- without letting the fuel level get below 1/4 tank.

US gallon = 3.78 litres

Are you working in US mpg (3.78 litres/gallon) or imperial mpg (4.54 litres/ gallon)? Edited by thegoose on Saturday 28th June 23:48

ras62 said: US gallon = 3.78 litres Sorry, meant to type 3.5 not 2.5, have now corrected it to your more accurate figure, thanks.

I get 30 in my 3.8 911, including fast bits in Germany.

My average on the Cayman is around 450km - 280 miles but that's a horrible mix of stop/start for a while followed by me booting it on a highway to make up time. Most I've had from a tank, going by the trip comp, is 600km/375miles.

My mrs has a Eos 2.0TDI CR which is capable of 60mpg and she is questioning the reason why we should take the Boxster , we will be doing a total of 2200 miles,working out the costs then adding grin factor after is why i asked .... Got to say i want to go in the 987 as we are taking in the route napoleon on route to Sainte Maxime and its been a burning desire of mine to do this for a while.

Surprisingly I'm now getting over 500 miles per tank from a 981 2.7, 45mpg on a run is not uncommon. It was impressive out of the box but now with 16,000 on the clock it's loosened up and delivers more bang for your buck as well as more go. Might help convince the OP's other half of the potential frugality of a Porsche..

Just get in the Porsche and drive it. Using the "mpg logic" you will forever regret doing some of the best roads in Europe in a crappy car. Even at 20 mpg in the Porsche vs 60 mpg the actual cost saving will be negligible compared to the value of the driving experience. Just do it!!

ras62 said: US gallon = 3.78 litres Ah, yes. Thanks for that.

There can be some fun in attempting to get good mileage out of the car. On long road trips where I spend hour after hour for 10 or 12 or more hours per day driving and of course can't push the car anywhere near its limits I find that attempting to maximize fuel economy becomes a nice diversion, a contest against myself to see what I can do. I don't go crazy by driving 55mph or coasting or shutting off the engine at every stop. I'm not a high miler driver but just seek to (within reason) wring the most out of the car when I can't wring the most out of the car -- if you know what I mean and I think you do -- when I'm driving.

Friday morning the ferry door comes down on the French side of the English Channel and I then have a 650 mile motorway trip to get to Vielha in the Pyrenees by evening, ready for six days of driving through the mountains of Northern Spain and ferry back from Santander. I'm also interested in MPG as driving through France will be at a constant 80MPH as I will not let the Gendarmes have a penny of my money for speeding. I'm driving a 993, and thought she might average 25MPG on the way down which would be around 26 Gallons to get there. I was thinking filling up UK side at the ferry terminal then just once on the way down through France as fuel in Spain is so much cheaper. Does this seem attainable?.

Can't say. You can just head out and see how it comes out. It is not like you can't fill up again in France if you don't get the mileage you need to make it all the way to Spain before you need fuel. If you want some higher level of confidence use a NAVI unit to plot a route and from this you'll know the miles, then you can work the numbers to see if what you want to do will probably work. But you can't always count on a clear run. Traffic or something might slow you up and there goes your plan. Once in awhile I do something similar. When I have to drive through Oregon I try to make it on one tank of fuel. There is no self-serve gasoline stations in Oregon and the attendants have a reputation for screwing up by overfilling and getting fuel all over or scratching the car finish or something. So what I do is fill up just before the CA/OR state line -- although fuel prices are generally pretty dear at the stations there -- and then drive all the way up through Oregon. (Or on the way south I fill up inside of Washington state and then drive until I'm back in CA.) The last time it got a bit iffy as I was in the Turbo and it doesn't get as good as fuel mileage as the Boxster and it is over 300 miles up through Oregon. But the Turbo has the OBC and I watched the miles remaining and was ok. I filled up just a few miles out of Oregon in Washington. It didn't help that the speed limit in Oregon is just 65mph (or less in places) and the Turbo (and the Boxster) appear to get better fuel milage at a higher speed.

I've worked out its a 2275 mile round trip down to Sainte Maxime then a three day stop off in Lake Como shooting back to Calais then home to Derby , at an average of 1,50 a litre it's going to cost!!!

It's going to be an awesome experience. That you'll die later and become nothing - enjoy iy while you can mate.

I did ~2600miles around Europe in my 987 3.2 last year and I spent less than I had calculated before the trip so don't worry about the fuel cost!

I easily get 400 miles on my 3.2 Boxster 987. Roof down around 380. Steve

V Power prices are a bit scary in Italy. Paid over 2 euros a litre there.

Got pump service in a few garages in Italy. They cleaned the windscreen too.

In towns and cities they close for lunch for 2-3 hours and then from about 7:30pm to 7:30am. During the closed times you have to use the "24hour self".
