JB '87 944

I'm a new owner and haven't gone through a full tank of gas yet on my '87 944 - 55,000 miles. With what little highway driving I've done, considering economy, engine labouring, carbon build-up etc, is there a reasonably accepted speed/RPM that should be maintained...say on a level road? Any comments are welcomed. Thanks. JB

I've always been a fan of the old adage 'drive it like you stole it.'

My car seems to be happy around 85mph or so (in 5th gear of course).
Don't know if thats best for gas mileage, but the car seems to like that as a cruising speed.

I never understood that one. I've never actually stolen a car, but if I did, I'd drive it in a way to attract the *least* amount of attention possible. Which means, under the speed limit at all times, and obey all traffic laws.

Personally, I prefer to drive like a mental patient who dipped into the methamphetamines before escaping.

I tend to drive like I was dipped in methamphetamines all the time.

The most economical is to leave the Porsche at home and drive the "Skoda". When I'm in the 911, I drive like it's the last day of the lease.

Drive it like you rented it.

Seriously, I think your gas mileage is more dependant on the way you drive on the highway. Leave a lot of room in front of you and see how long you can go without using your brakes. THis applies in stop and go traffic. It's better to stay in first with high revs than to go, shift into second, brake, downshift, wait, go, stop...gah...Just cruise slow.

Don't lug your car. It likes revs. I try to stay above 2000 at all times, fifth gear's good until you slow to about 60, I think...unless your cruising...I dunno. I don't think this is the right question to ask. If you worry too much about your gas mileage, you'll end up fouling plugs or gumming up the...what, the kishkeys?

So...the highway drive was completed today. Must admit I couldn't keep the speed consistent (100 k - 140 k or 60 mph - 90 mph)..hey, I had to have my fun, but when all was said and done, the average was 11km per litre...in imperial gallons per mile thats about 30 miles per gallon ...in USA terms (128 oz per gallon vs. 160 oz for imperial) that works out to about 24 miles per gallon. Thanks God miles are miles...in both lingos. So my American buddies...does this seem about right?

Somebody asked this question in a Road and Track mag a while back. Seems like they said that most cars get their best gas mileage at about 60-65 mph where a proper ratio of gearing and engine rpm's meets. But as we all know, the 944 isn't most cars. If it was I'd be able to change the daggon thermostat in about 20 minutes.

i drive an 83 (so keep that in mind):

rough estimates of when i shift/cruise:

top of third @ 60 mph

cruising at 4000 rpm in fourth @ 80-85+

shift to fifth to cruise, speedo reads 80 rpm, 3500+? gal/hr is somewhere around 25-30.

i generally don't use 5000 rpm or higher. i usually stay around 4k.

i HATE the imperial system! why can we all get along and use metric?

2,200-3,200rpm will generally provide the best economy. I believe I once read that our cars perform best at 56MPH which I believe is right at 2,200rpm.

RIGHT, Don't buy a rental I have driven.

OK, answer the question!! keep it at 60 in 5th with the cruise set.

I drove back from Frankfurt(about 70miles) at around 100MPH and got around 23MPG. I think it depends more on, are you on and off the gas, and the terrain, hills ect.
