That's funny about the diesel...I hope you're kidding, though. I always use higher grade fuel in everything, it's just a habit. At least in a nice vehicle with a modern engine. And SNiiP3R, I did read through your post again...in fact your last reply was directly after another person who also quoted you on the regular fuel statement...I don't know if you're leasing or not and I don't mean to judge or anything like that. All I'll say is, I would always use higher octane fuel in a vehicle like a GS just because it is worth taking that extra care of and, like I said, it's a habit.

I just find it interesting that people spend $10000 or more extra to buy a nice car and then don't want to spend the extra couple of bucks on premium. In the Chicago area we are getting raped for premium because most stations don't post premium prices and they are now 40-60 cents more than regular. But when you add up the difference each fill up it is less than $10 a week so over a year isn't it worth $500 to have more performance. And this doesn't even account for the better gas mileage with premium, which most studies say is a benefit.
In my range in the Bay Area the gap is $0.17, so a no brainer to use the good stuff.

Premium and that's all I would use since the car demands it, I have found (when I used a loaner) that when I put regular the gas range is shorter because the only way for the car to be efficient is to put the gas that is required or you will get less gas so in other words you will be paying the same for premium because you will need to refill quicker.

Question for you...your experience about the gas range being shorter, is that because you filled the car up with regular and drove the whole tank range, or are you looking at the range the trip computer calculates when you fill it up before you turn the loaner back in?
The trip computer range has a lot of variables, thats not really evidence that regular fuel provides a longer range.
I was always a huge proponent of premium fuels, and then at the urging of my mechanic I stopped using premium in my 2010 ES and honestly saw absolutely no difference.
That said, I do use Premium in the GS because it is a higher performance motor, direct injection, etc, I have no plans to go to regular.

This was an RX and the car was driven to near empty and then refilled with regular gas and the range basically stayed the same. The car had super before when the car was given to me, and I didn't care what I put in it as it wasn't my car. I know that the range has different variables, I have based it on this and have noticed the same thing in my BMW the gas basically goes quicker than when using premium.
If the car is yours, just use the manufacturer rated fuel, they recommend it for a reason. The computer will compensate for lower octane gas but if you plan on keeping the car don't use it too often if at all.

On an RX especially, the engine is actually okay to run on Regular. Look at Lexus.com. Putting premium in a car designed to run on regular isn't going to improve fuel economy.

I had an Avalon and noticed that it always ran much smoother on 91 grade. I mentioned this to a friend who is an engineer with Ford and he laughed and said, "Yeah the Toyota V6 always prefers premium gas". The Av also ran better when the temperature was17 Celsius (60 F).
