That's amazing, a 270 hp car getting the same mpg as my old 190 hp Camry.

I have a 2004 TL with Nav. In mixed driving I get 26 mpg. On pure highway
I can get 29-31mpg. I don't consider myself an aggressive driver.
As for the gas, I use regular and premium. Unfortunately, it's difficult to find 91 octane, so I have to use 93 octane. I don't see any noticeable difference in
MPG when using either grade of gas.

I don't think it's mph as the reason to use premium, I have read it has to do with the computer that tries stop knocking. It is my understanding if you don't use the right gas it could mess up the computer. As you can tell, I am no mechanic, so I would appreciate a mechanic's opinion, please?

Frisconick....Here is an interesting article regarding the use of Premium Gasoline and effects on a car:
   
http://www.usatoday.com/money/autos/2003-07-30-premiumgas_x.htm
    
Essentially...it is USA Today which quotes a senior Chevron Exec to saying:
   
"I personally use regular even though my owner's manual says you'll get better performance with premium," says Lewis Gibbs, consulting engineer and 45-year veteran at Chevron oil company. He's chairman of Technical Committee 7 on Fuels, part of the Society of Automotive Engineers (SAE) Fuels & Lubricants Council. Gibbs knows gas.
 
I am still interested to learn if it could mess up the computer or other parts. I honestly don't know. One thing I do notice is that my MPG goes up by 1 or 2 mpg when I do a 50/50 mix....which I also don't know what causes that (please...someone help me to understand that one)
 
[I am still primarily a premium fuel user ...]

Thanks for the link, I will read it later. The Chevron exec isn't too smart, don't they make more money on primium?

Filling it up..... by nightcrawler29

Well today I went to the gas station as I was runing practically on fumes, and that little light by the "E" was on..... so got lucky and found a gas station in the middle of nowhere, and pumped in some 89 grade gas..... this is the 3rd time I fill the tank since I bought the car and haven't seen a gas station that sells 91 grade...
Anyway, according to the manual, this car supposedly has a 17 gallon capacity isn't it??... today I filled the tank with 13.95 gl. (and I mean filled it) $2.25/gl of 89 grade. Total gas pumped amounted to $32.15.
 
Last week filled up tank with 89 grade as well, and run the car for 335 miles (in city and highway traffic) before I ran out of gas today. Per computer, MPG was 25.
The car has been runing really well, and haven't noticed any problems due to gas being lower than required 91 grade...... I sort of wonder what grade of gas the dealer put in when they gave me the car when I bought it....

I have a feeling my initial tank of gas was 87 grade. The car ran a little rough...but once I got a few tanks of premium...pure smoothness.
 
So nightcrawler...are you planning to do mid grade 89 going forward? 25mpg is pretty darn good in mixed traffic compared to a G35 that gets 25mpg pure highway.

wow 27 mpg in mixed driving is really good!! what did you do frisconick?? did you got out of the car and pushed it when you where in traffic?!?!... well as you said, that's pretty good mileage for a 270 hp car. Have you been pumping in the 91 grade gas? Not sure if it makes any difference if you pump in grade 89 versus 91, but would like to know from someone who has tried using only grade 91 or even 93. So far I have used grade 89 and its been doing real fine. Now, I'm not sure what could be the difference between grade 87 and 89... maybe the price I bet.

Well I have to admitt that about 60% of the driving has been on the highway. I have only used 91 or 93 gas, but I don't know if this makes a difference. Plus I have cut down on gunning it.
