Not too difficult to get 400 miles to a tank. I've knocked down 24 mpg on the high way in my 04 Coupe, 6MT.

 

Anyone consider he changed out his tires for a non standard size? That would change the reported miles per fillup & be inaccurate.

 

best is 14.3 (and this is at a track that is about 1200 ft above sea level in relatively hot conditions)... the 14.6 I have no idea where you got however it could be LACR which is more like 2700 ft above sea level and the last time I was there it was well over 90 degrees at night!!!

Dave - when I post 271 HP you poo poo the dyno... however you conveniently use the worst tracks in the nations (ours) as your feeble attempt to heighten yourself... as for not knowing what my car has - well that’s funny you always have poo pood most of the mods that have been discussed... I'm not going into all the things my car has - let me just put it to you this way... no G or Z that is N/A has beat my sedan on the track or in spirited safe (open road) street run... I have absolutely no doubt whatsoever that your car would lose worse than the majority I've come across...

And no, 3.7 FD is not all I have There has been much more than that for quite a long time…. it's surprising you don’t know this since it has been discussed in many threads – and historically you have downplayed many mods… I don’t know why you say you haven’t – many of us that have been on this forum for a long time (some that don’t bother with you anymore) know all about the hypocritical stuff you pull….

As far as me not posting in 1/4 best times... like I said, you will not find ANY decent times on the tracks I run… It’s funny how you search for times posted but don’t come across videos… You’re solo 14.3 ET is really nothing to boast about – especially considering the tracks you have access to have very favorable conditions (comparative to the ones I’ve been on)

The reason I stated I like smokin’ cars like yours – is because you often make comments like you did – the 3.7 isn’t doing much for your mileage… you’ve said things like that about other mods too (not just to me, I’ve seen you say similar things to others)… the fact is I have ZERO concern for gas mileage… everything (well most everything) I have done to the car is to make it faster… thus the statement I made.

You can keep hiding behind your forum talk – but as far as the capabilities of my car – there are several that know what it can – and it’s not because they read cr@p out here… they have driven it or raced against it. Are you able to honestly say any of this?

By way – I NEVER say this to anyone else… I have never called out the ones I’ve beaten or mentioned it in any way… I don’t need to. I only do this with you DaveB because of the comments you make.

Edit: actually after thinking about it - I remembered WaLLy beat me once at Irwindale (1/8 mile)... very nice Wally!!!! (didn't want to shun you bro )

 

Cry me a river and the exact response I was expecting. Guess what? I'm not your keeper and I'm not going to search every post that comes up with "OCG35" and "1/4 mile". My track sits at 1100' and conditions aren't always favorable to racing. In 1/4 mile drag section we takes things into consideration like density altitude which levels the playing field. Also, my car has done four 14.3s which is hardly a "solo" 14.3.

As for the 14.6 that you have no idea where I got it from, that's interesting because you just ran it a few weeks ago. It's the quickest documented run I could find for you because everything else that turned up was 14.7 or greater. post 250 https://g35driver.com/forums/showthr...ght=1%2F4+mile

That's fine, but don't come into this thread and tell us it's absolutely impossible that some of us can get far better mpgs than yourself.

 

I will admit that in this thread many people have mentioned that 400 per tank happens... however, most (if not all) the previous threads I've read about gas mileage showed nothing but low miles... granted I haven’t looked at gas mileage threads in quite some time so newer cars are probably seeing much better mpg - AND, like you I am AT, which I still doubt people are seeing 400 per tank full unless running bone dry (AT that is).

Bark all you want about racing Dave - I absolutely am confidant that my car will beat you. I've said it every since you began stating that mods do nothing years ago... When I had the time and resources available I offered to come towards your area and meet somewhere to race… You never took the challenge. I truly hope to have the time again, because I would nothing more than to end this bs with you once and for all.

My car will absolutely smoke yours. Period.

 

Doubt all you want. I know how to do math. 400-480 miles divided by 16-16.5s gallons equals 25-29mpgs. My car and handful of others see the same thing.

You need to get it out of your head that I care about how fast your car is. I never once said my G35 would beat yours and I really could care less. And I'm sure as hell never going to drive over 50 miles to race someone to stroke their ego. Does it not sound a bit childish to you at all? If you're in Kansas City, then I'll race you at KCIR otherwise get over it

 

Dave - it has absolutely nothing to do with "stroking my ego"... never has and you know it... has EVERYTHING to do with all the times you said certain mods don’t do anything... stop playing coy - you know exactly why I've challenged you to race so many times... There have been MANY posts by you that various mods do nothing... why do you think so many people got fed up when they did testing and had real world driving impressions and you would come out with your bs about things not working in theory... multiple times I've stated that with all your "racing experience" you should be able to win hands down in a race - certainly if the mods you oppose to do nothing... You act like this is all new to you... I've always professed that the mods are very viable and thus the challenge to race.

Very convenient for you to step around the history and true facts about where this comes from Dave. Just because you want to shed a bogus light to those that don’t know about the anti-mod history you have...

To all that are unfamiliar with the history behind this... Take my advise - do as much research as you can before you apply DaveB’s suggestions... there are many people that know what I am referring to and do concur.

Dave - continue to blather you're nonsense... I'm done with the foolishness with you. Oh, BTW - I completely call BS on your AT getting 25-29mpg (give me a break )

 

Ummm does anyone else see the irony here? My 2003.5 5AT, bone stock with 93 octane, has made it the 410 mile one way trip from Boston to PA at least 6 times now averaging around 75mph with the fuel light only coming on at the very end of the trip = not bone dry. This includes traffic slow downs and running my AC the whole way. Real world driving impression, not magic, not BS, not bone dry, not downhill, not drafting behind a truck the whole way or whatever extenuating circumstance you want to imply, it's a fact.

Also on a side note how does the 3.7 feel after you've had a chance to get used to it? Any drawbacks besides the gas? I'm totally willing to sacrifice some top end and mileage for more low end torqueiness, so this might be the big winter project this year.

 

I call BS on you being an adult.

 

sp?

hmm, 25-29mpg is quite high tho.

 

For this site, I guess it is. I have had the car for nearly 3 years now and it consistently gets the same mpgs, month after month. It must be the way I drive, the fuel grade I use (BP 92), the fact that I don't have a lot mods, I don't do a lot of short sub-5 mile trips, don't do jack rabbit starts, and I don't have aftermarket wheels which can suck out mpgs. I'd say over 95% of the time, I keep the rpms below 2700rpms. On the highway, I set the cruise at 77mph or so. In the winter, I see about a 10-15% drop in mpgs due to the extended cold starts. My old VQ30 in my 5MT Maxima saw about 10-15% higher mpgs.

I think the reasons people see such crappy mpgs in these cars is because one or more of the following reasons:

1) Mods, especially exhaust mods. For whatever reason, adding things like true dual exhaust and test pipes/HFCs seem to make these cars run really rich under part-throttle driving. When I had a Borla TD, my in town MPGs went from 20 to 14. Same driving style too. Getting 230 miles on 16 gallons was insane.

2) Wheels and tires. Larger, heavier, and/or wider wheels and tires will kill mpgs.

3) Frisky driving, especially in a 6MT. Once you take the rpms over 2800, your mpgs are going to suffer, especially around town.

4) Short distance driving on a cold engine. If you make a lot of sub 5 mile trips on a relatively cold engine, you should expect your mpgs to be dismal. A hot engine is an efficent engine. A cold VQ35, especially in the winter, could be getting as bad as 8mpgs during it's first 1 to 2 miles of driving prior to full warm up. If all you're doing is a lot of 1 to 5 mile trips, your mpgs will be dismal. It wouldn't be surprising to see 12-14mpg in this type of driving.

5) Drivetrain loss. The 5AT cars have a relatively high stall TC. It's great for performance, but not so great for city mpgs. The X cars have a lot of rotational weight and drag thanks to two additional half shafts, a transfer case, and an additional driveshaft. Even when the system isn't spliting the torque, there is still a large loss from spinning all that mass.

 

i get 400+ miles all the time.. i do about 90% highway.. getting 24.6 mpg according to the NAV info.. i think pumping 93 octane will fair even better..
i wouldn't pump 87 in my car.. to prevent knocking~

 

there are a few reviews on this site and my350Z (in the appropriate threads)... this one has gone off topic enough.

 

I don't have the trip computer so I don't know the exact MPG but I drove from Ft. Bliss Texas to Southern Cali. with one fill up in between and had 1/4 tank left when I got home. Yahoo maps is telling me its just under 900 miles to my house, granted it was all freeway driving I had the cruise set to 75mph. I do think its possible with the right driving style, on average I get around 21-22 MPG mixed driving normally. Oh and I use 91 octane, only mods I have are coupe mid, K&N, z-tube, coupe springs, and new rims.
