I get 200. Wish it had a bigger tank so it got at least 300 before needing to be filled up.

Reeko

I ussually get the light at 190-200 miles.
When I fill, it is normally at 200 and 13.5 gallons.

I have only once gotten 220 out of a tank. But, I am all backcountry road driving. Lots of accelleration and starts/stops. Plus, it is about an 8 mile commute to work, so most of the driving is while the car is warming up. (I would consider country roads more like city driving. No sitting at the light, but lots of stops/starts at intersections.)

Ophitoxaemia

ive been getting the light about about 240-250 in mixed city/freeway driving, took it to 290 on a tank once on a long drive. this is driving under 80 usually and not too many full throttle accelerations.

My dealer in AZ is telling me that the engine will run better on 89. Anyone else been told this? I am on my second tank and the soot out of the tail pipes is almost gone. Plus it seems to run the same or better.

The Rotary engine injects oil in with the fuel (probably a better technical explaination that mine) to lubricate the seals. In doing this, the octane of the fuel is reduced. I am unsure if the drop is linear, ie 98RON fuel will drop to say 88 and therefore 89 will drop 79.

That said, I have just run my last 2 tanks on 91RON Unleaded (the lowest we go) after running on nothing but 98 since I got my car in Feb. I have to say that the car feels like it runs better and is more responsive. I am driving it harder and my fuel economy is no worse. Next tank will be gently driving to see if it does get better.

I have also been driving with DSC totally off if the roads are dry.

I average 340 Kms (200 Miles) per tank where I fill up with around 55 litres (12.1 Gallons).

i usually get 200-240 in mixedusually aggressive driving. On long trips though of less than 300 miles i will get 260 to the tank. But for some reason on trips in the 600-1000 mile range the second tank ends up lasting 320-340 which was nearly 25mpg all at 75mph+...wierd

WOW...talk about bringing a thread from the dead...lol

I get 250 miles with all city driving with no problem using about 13.x gallons. I've never used up more than 13.7 gallons in my 8. I also have never taken my 8 for a trip (long periods of time on the highway) either so 260+ is the max I've gotten on it so far with no less than 249 miles on it with all city driving.

I probably average 252 miles per fill up @ 13.x gallons used.

You DO know you're replying to a post that is a year and half old, right?

LOL...I did not know until I saw Speed-er DOC reply about what he got, and then I decided to look at the dates....lol

CrowBoy66

I use 91 octane and it never fails 220 miles no matter how I drive. I'd say I drive 60% highway 40% city. This is true before and after mods(RB Exhaust, RB Intake)

Glyphon

when i filled up yesterday, i got 240 miles out of 12.5 gallons. guestimating 50/50 city/highway.

RotaryNoob

180 per tank average. On a road trip the best I got was 240. As soon as its warm I redline up to the speed limit 80% of the time.

91 Octane

scarroll

I use 89-93 ocatane

I drive 60% city 40% highway.

I never let the rpms get below 3400 unless at idle.

Shift at or near redline 80% of the time.

The low fuel light comes on at 255 miles just about every time.

and if I fill up right then it takes 13.2 gallons.

I have gone 290 on a tank without running out of fuel.

Could tires be a factor? I drive my friends with stock potenzas

and I can't get it 220 before the light comes on.

But mine came stock with Dunlops. Thoughts?

Elara

Nope, not the tires, because I drive a lot like you do, and I had the stock potenzas (now pirellis). No change in my mileage. Usually between 250-270 per tank, about 12.9 to 13.4 gallons per fillup.

jangle

18-20 MPG. I drive mostly highway.

Huge change from the infiniti Q45 i used to drive....22.5 gallon tank, about the same milage....could get 420 miles on a tank! (though it cost $45 to fill her up)

for the record, I've been getting 16/20mpg in city/hwy. usually 89 octane.

RotaryIT

The usually get about 200 per tank when driving 70/30 city/highway...93 octane.

My best, was on a road trip to Kentucky. I stopped to buyu gas after 175 miles....could not pass it up...it was 93 octane for $1.98 in Ohio. (Michigan was $2.42). It took 6.5 gallons to fill back up....which equates to 26.9 mpg. The conditions were nearly perfect...about 65-70 degrees, low humidity, no rain, and traffic was smooth...I probably averaged 75mpg for the 175 miles. I probably reached 95-100 for a few moments here and there, and dropped to as low as 65 for about the same. I was very impressed by this...I was on N flash at the time.

On P flash, I had 23 mpg on the same trip, but my average driving has bumped up to about 18mpg. Getting about 230-240 per tank now.

zoom44

i can get 230-240 around town but usually get 200-220. i have had over 340 miles on 1 tank i think it was 342. with a little over 14 gallons refill for 23.99 mpg

Str8cold

I have been getting approximately 250 miles before the low fuel light kicks on, running 93 Octane 60% city 40% highway driving. Averaging 19.23 MPG

auzoom

Nothing like bringing the past into the present. Just as current musicians :-P

Seriously, it was late and I didnt notice. I tend not to care if its old...only if its relevant.

Sorry everyone. Please stop responding to this thread as its totally inappropriate becuase its to old :D Just kidding!
