It's just about the same

Maybe you should have researched the G35 MPG before you bought one if gas cost is a concern for you.

So my last post was to the 1st page. N/e ways, it depends on how you drive. If you have a lead foot, your going to waist gas. If you drive like a granny, you should be pulling close to 20mpg or more. You should be using 91 and not 89. It does make a difference.

n town i get maybe 220-240 b4 gas light is on but on interstate running 80 i can go 400.. sometimes n town i only get 180-200 to tank.. and gas here is 3.40 right now

LOL. Something so simple can be so difficult to some. Also, it depends on driving habits. The heavier your foot is and the faster you drive the more gas your car will guzzle up. shift gears under 3,000 rpm and drive the speed limit for best mpg results.

Here is what I get, per tank

Anyone know which gas is the best as in shell or chevron. I have heard chevron but curious others opinions.

It all comes from the same refineries.

chevron. always use what the manual says, which is premium, i avg about 22-23 mpg and i drive 700 miles a week 90% hwy. and yes im going to complain about the gas mileage cuz when i bought the car i drove like 75 miles a week, then i moved, so now its time to move on to a new car

04 auto i get 23.5 mpg with 93 octane. yeah it drinks more then my honda and my honda is faster, but i dont care cause of the comfort and cornering of the g35 =) im very impress with the car just got it a few weeks ago for the wife. kind of wish i got it for myself lol.

+1. But these cars call for 91, so putting 93 in it is also wasting money.

I average about 19-20mpg, but 80% of my driving is long distance highway, so

In some places 93 is all we got. Here in FL, its mostly 87 89 93.

In that case there isnt much you can do. I dont understand why they offer the octains they do in some states. 87-89 is the most common by far, some higher compression cars require 91, but 93? I guess if it's the same cost as 91 who cares? Id opted to run the mid grade though.

I average right around 17.5mpg. My best thus far has been about 25mpg but that was with an extended road trip which about 95% was interstate travel. I've been using 89 Octane with 10% Ethanol As well. Been meaning to make the switch to premium. Never really gave much thought to the idea that I'd get that big of a difference in mpg by making the switch, but If some of you guys claim it does, and it ends up costing the same in the end by the increased mileage, I'd be a fool not to make the switch. Now if It'd just stop snowing and would warm up so I could get rid of my sandbags and actually drive my car on a regular basis I'd be able to test it out.

When i had the G i used to put gas every 3 to 4 days and arround 40 dollars!
