Premium Gas Necessary for 07 Camry?

Thus, you get the Camry's 268hp rating when using 87 octane.

I believe it.
I also read that in so many words on another site when I was researching my Camry purchase and my daughter's Lexus purchase.
Although she bought a IS 250 and not the ES 350.

V6 takes 91. If you use 87, you get knock corrected ignition maps, and a loss of power.

The 2AZ could probably run on 85 octane. I wish I could find that for my 5SFE.

really?

87 all day long. Higher octane burns colder and not as effecient. Plus the car was probably built to use 87.

Same engine in the Lexus ES 350.
You should email the bigwigs at Lexus.
They'll notify their engineers on their mistake

You can have the same engine in 10 different cars but have 10 different tunes in each one all of which will want a different type of fuel rating for that tune. While one octane will run in all of them they might not get the best mpg or performance until you put the specific one in.

BTW how do you not know I am one of those engineers ?

I don't.

I'll just use 91 to get peak performance.
I believe it's the same engine as in the Lexus along with the same tuning.
Just like I said above,$4-$5 a month won't kill me.
"To each his own"

Just cracks me up when some will say it's a waste of money and they same people will put every accessory known to man on their car.

I'm betting that the Lexus has a different program in it. Just like with my truck, I can reprogram it to run better on premium fuel... but I won't get near the bang for my buck without the reprogram. Same goes for Lexus vs. Toyota...

BULLSHIT! My V6 Camry runs fine on 87 octane and with power to spare. I spare none!

The difference between high and low octane with each fillup is about $1.50-$2.00 per tank. That's about $25 per year. I'll take the higher octane.

No, those things just aren't related to each other at all. Higher octane will give you slightly better performance, which you either don't need or can't use in typical traffic. So there's just no need to spend the extra bucks. Simple.

Hee hee. Umm, some people might actually drive enough to burn more than one tank of gas per month.....

Again, if you don't need extra performance (and gosh knows what you "need" it for, unless maybe you're "street racing"), you don't need to spend a penny more for the higher octane stuff.

Agreed, same logic I use when I put 93 in my Lincoln vs the 91 it asks for. But I also get worse gas mileage with the 93 so the extra couple dollars at the fill up for the 93 which s no big deal actually ends up being quite a few more dollars later on because of lost mileage with the slower buring and less effecient 93.

Also on my Lincoln I tried 87 octane. It was noticably slower because the computer probably pulled out timing but it did get 3-4 mpg. better in town to boot !
