Wow, I must baby my car more than I thought.. I just bought it a month ago, and love it! So far I have been getting 22-23 mpg in 'mixed' driving (though I live in a very rural area without a lot of traffic and stop lights), and 27-28mpg on the interstate (cruising around 70mph). I don't romp on it everywhere I go, but I do go WOT occasionally. I run Mobil 1 5W-30 and have the stock 16" wheels. I'm amazed that this car only gets about 1-2 mpg less than my Talon does.

I'm currently at 23.9 total over my first ~6k miles. I'm going to guess that that's at least 60% freeway, maybe a little more.

for my gs430 i average about 17 mpg, probably only 15 in the city and w/ a heavy foot, and with all freeway driving i can get about 24 mpg.

XYZ, I think you're one of the first person that I've heard putting in 87 into the GS. Does it ping under hard acceleration?
Wow! they have 93 octane in NY??? Our super unleaded here in the SF Bay Area is only 91 octane (regular is 87 and mid grade is 89). I wish they had 93 over here. Yes I put it 91 octane everytime, wouldn't even think of putting in anything less.

Ditto in NYC. I wished we had 91 instead of 93. I'll be saving a little bit of money everytime I stop by the pump.

half a tank of 93 + half a tank of 89 should more or less = 91

that's what I've been doing to save a nickel or two

I guess that works, however, I'm too lazy to do that. Plus that would also = more complex math as I calculate my gas mileage on every single tank.

Okay, but what is your 93 going for per gallon there in NYC? Out here the 91 goes from $2.29 to $2.49/gal which I believe is more than over there. For that matter more than all other 49 states. Oh, and don't even talk about housing, we have the dubious distinction for the highest, most outrageous prices here ($500k for an average starter home). See, if we didn't have to spend so much on mortgage/rent we could spend it better on mods and more cars. Dang, the upcoming new generation GS sounds sweet on paper.

I usually try to buy gas in NJ where it is much cheaper. I get 93 for $2.25/gal in NJ. In NYC, I think it is around $2.39/gal (someone who pumps in NY correct me if I'm wrong).

Now this is Off Topic in response to your off topic comment about housing cost: Housing is crazy in NYC too. I live in a house that is 20ft x 35ft. Two stories, no garage. It is worth over $600k

And to top it off, my house was built in the early 1900s. I think it was built around 1908 or something like that. So for a 2 story house that is 20 x 35 that is almost 100 years old to cost over 1/2 million dollars is almost unbelievable.

I was pretty amazed with my last tank. I got 407 miles to the tank and probably could have gone another 20. Pretty damn good for a V8 I love my car
