Decided to see what kind of mpg I could get
Our of curiosity I decided to see what I can manage in the new car to compare it to the old one ('95 Miata)...
Speed was between 65-70mph. The route was 90 miles. 12 of those miles were stop and go driving. I managed 37.3 mpg I figure 90 miles should be enough distance to eliminate the error in pump shut off and give me a decent estimate. That's impressive to me considering the miata got 36mpg and has 400 less cc's and turns about the same rpm. So for all intents and purposes the two cars get about the same MPG, but the miata weighs 400lbs less. |
thats pretty good mileage! best ive gotten is 31, ALL highway, cruising at 75.
|
i'd say that pump error could still be counted for, cause that's less than 3 gallons, and the pump cut off could easily be up to a quarter gallon, which would be about a 8-10% differance, so it could be anywhere from about 34-40mpg by that count, still great.
someone needs to go on a long trip with the s and do a full tank without any fun to see what it can get with full certanty. still i'd be happy with even 30 for a rt. i know that in my lude i got an average of 34mpg to WA and back, and that was wit some spirited passing, so i'd say with strick driving it could get about the same as well. |
That's amazing mileage (at least to me it is). Was this round trip? Just wondering if mileage was enhanced by a lot of downhill driving (maybe your endpoint is at a lower elevation than your start point?). But, seeing that you're in FL I doubt this is the case.
I've owned my S for 1.5 years and 9k miles, and I haven't even hit 30mpg average for a tank yet. But then again, my driving is about 70/30 city/highway, and I've never done a highway road trip so it's tough to compare. I :heart: the F20C & F22C -- performance when you want it, great mileage when you're just cruising. :thumbup: |

BTW, I calculated my city mpg (yes, strictly city driving) and average 19.1 mpg. That's with hitting VTEC almost every time before shifting into the next gear. :)

that's crazy mileage... wtf

If it helps any, I get about 26mpg in my regular commute which is about 70hwy/30city. Even with the possible error, I'd say 35mpg is attainable in this car at speeds below 70.
|
yea i believe someone did a test a bit back and they got pretty good mileage even with top down the whole ride.
37 is prob. an error. that's like....hybrid status. but this is what i love about this car too. you will probably never see anything over 30 on a Z. the fact that you can get 30 mpg all highway doing 75 seems really good to me. |
Best tank: (AP1) OEM hardtop on, cruise set on 74mph, mostly flat ground. Entire tank just over 30mpg. 337 miles and 11 gallons I think it was.
Earlier this summer I drove an entire tank in mixed driving, but shifting at 4K in first, then 3.5K all the way to 6th. Got 29mpg on an entire tank, but it was so painful I will never do it again :) I typically get 23-24 driving it how I like. |
I don't think 37 is possible. The best I've ever gotten was 31 with a bit of stop and go but mainly cruising at 75 on the highway. I think 33-34 is possible on flat with cruise control pegged to ~75, but 37 is stretching it especially when 13% of the driving was stop and go.

Me here, decent accel , hitting vtec maybe 2-3 times a day (summer) not to much anymore because its colder out. 4.77s , I average 26 mpg, 70% highway driving. With the high rpms with the gears, i bet if you wanted the S for a gas car (not sure why) but if you put a crazy low rear end in it like a 3.10 or something I bet you would see over 45mpg

Ive gotten 33mpg with 50 degree weather and no vtec ranging from 65-75mph. AC was off and windows up.
37 is up there.. |

I guess it would be possible if you did a lot of coasting down hills.
|
I got 200 miles out of a half tank before. that one was crazy!
|
[QUOTE=vtec9,Dec 2 2008, 12:04 PM] No way.
|
Draft big SUVs and trucks and you can get at least a 10-15% bump in mileage. I used to watch the little instantaneous MPG calculator on my Mazdaspeed3 and it would literally jump from 30 to 33 if I tailgated a big semi or even just a larger SUV.

On my way back to NOVA from Virginia Tech, I drafted behind an Escalade the whole way, going 80-90MPH. My gas mileage was like 34MPG. I made it home in about 3 hours. LOL!!

Its like saying cruising at 5mph in first gear (say like 3k) will get you the same gas mileage at 60mph in 6th gear (3k)

I've done a whole tank once without any fun.
It was raining heavy all day and I had to use my car for work so decided to just cruise. It was all motorway driving. Got 365 miles out of the tank. Worked it out after the refill and calculated 36.5 MPG. Oh yeah that was on Super Unleaded (99Ron) Pretty pleased with that :) |

I'm assuming he filled up 10 gallons??
|
hmm so i guess big SUV's do have a use other than being the aholes on the road...i guess i should try drafting lol.
|
you guys have no fun. The best Ive ever managed is 25mpg :LOL:
:rev: :burnrubr: :vtec: |

How many of you have filled up your tank with more than say, 11.6 gallons? I'm trying to find out the range of my car on a full tank. Everytime I fill up after driving with no bars for about 30 miles, the most I've put in is 11.6 gallons. This weekend, I put 10.8 gallons in after driving about 20 miles on no bars.
The digital fuel gauge is the only thing that really bothers me on the S, especially when I gain a bar without filling up! Quite perplexing. |
11.511 is the most I have ever put in.
|
Jeez...37?! I didn't think that was possible. I'm averaging 21mpg h/c mix. Normal driving with very minimal WOT. I dropped about 2-3mpg after I went from TP/exhaust to stock cats/exhaust on average.
Most I've ever filled up is 11.6 as well. |
Well it was quite a while ago so I cant remember how much fuel I put in or the price per litre.
Anyhow I worked it out as follows:- Cost of fill up ( |
man that seems really high...i dont understand how you guys get such great gas mileage...typical for me city driving/mixed highway 18-20 mpg
all highway cruising- 22-24 mpg the best i ever got was 26.6 mpg which was a 7 hour road trip bringin the car home 65 and under and all of these are without revving the car up into the vtec range and i have been taking gas mileage on all my cars since the day i got them...got books and books of it.. it makes no sense to me ....my car sucks lol |

It isn't. His calculations are clearly off. No amount of short shifting or slow driving will get an F20C to 37MPG.

I get 22-24mpg in mixed city and highway driving and with hitting VTEC every once in a while. With my car, 37mpg sounds impossible.
Good thing gas is so much cheaper these days. |
I average 25 MPG with about 50/50 City Highway mix (VTEC pwns me :LOL:). Also, as I mentioned I got 200mi on a 1/2 tank all highway ( refilled from half to full after the 200 miles and it was 5.3 gallons). That's 37.7 MPG. So it is doable. I am still suprised because I was cruising at a pretty high speed for fuel economy (75).
|
I agree. No way 37 mpg. Ive pegged my cruise control at 73 driving across texas with a full tank of 91 octane and the best I could do was around 26-28.
|
Maybe thats the difference then.
I run on 99ron petrol. (Super Unleaded here in the UK) I notice a difference in my MPG when im forced to put normal 95ron unleaded. Never actually done a proper MPG test tho. So I recon 91 ron must be a massive difference. |

Don't know how the hell you people drive but I cant seem to manage more than 22. Granted I need a new air filter Badly... I think vtec is the bigger issue.

The best tank I ever had in my AP1 was a little over 28mpg with an average speed of 90mph.
