Can you be any more vague?
A car does not get use to anything, it's a vehicle, not an animal.
It's you who gets use to filling up at the same location, as do most of us.
Just don't feel up when the tanks are empty, you may get sediments in your fuel tank. But in reality, it really makes no difference. If you do not maintain your car, no gas brand will help you.
Like ElegantTypeS has mentioned, yeah, additives result in better mpg but at what cost in the long run?
This will be a back and forth argument, there is no valid benefits from one or the other 'brand'. Hopefully one day, all cars will run on water, and will be arguing Poland Sping or Aquafina?

I apologize, I didn't read it as 91 octane vs 93 octane. I read it as someone buying cheaper gas because it's 2 cents cheaper by the gallon. I've talked and argued with a lot of people who would rather save 30 cents at the station than save the engine in the long run. We get a lot of, "Well, I'm selling the car, so it doesn't matter what I put in there." at work. Just remember, gas burns differently at different octane levels.
i was just arguing for "1995hoo".In any case, I do agree that you shouldn't be looking to save a few bucks by filling with 87 or 89 octane compared to 91+, since our high-compression engines require higher octane gas. You can argue that the engine will retard the timing to compensate, but do you really want reduced performance? There's also still a risk of pre-detonation, even if the engine is adjusting for the lower octane fuel.

I can't figure out how to merge my posts 
Would you care to elaborate? What do they think differently about?
I think what you're trying to get at is how the ECU will adjust for differences in the fuel mixture, but realize that the differences in the additive packages are pretty much negligible for high-volume stations such as Chevron, Shell, BP, etc. What matters is how well the station is maintained to ensure that their pumps are in working order, filtering out the particulate remaining in the fuel, so that your car doesn't have to.

In order to listen to mechanics, you need to understand them, and I doubt that you do. You are young, you'll get the hang of being wrong while learning.
A real mechanic will tell you this: oil, gas... whatever..same bullshit. Why? because they know better as they are dealing with cars all day long. Ask them, how many of them reuse the oil (after your oil change) in their own cars.

And just to tease, driving home yesterday on Route 1&9 NJ to NY:
Shell Reg $1.59
Shell V-Power $1.98
I'm getting a hard on with these prices, just hope they last to the summer so I can take advantage of this on my trips.

Though lately I started to think about this, same hose dispenses all grades of gas at the pump, though the contamination is almost non existent, it bothers me.

I can't remember seeing 93 for under $2 a gallon since before I bought my TL in August 2004.

I ran BP and Mobil and never had a problem. Recently I put Gulf since it was the only convienent station around and again never had a problem. I don't put Shell since it cost more and they ain't that many station around here in queens compare to Mobil and BP. My TLS runs fine as long as it is 93 octane.

One thing I find interesting is the assumption of many here that your chosen brand will always be the best. You can get bad gas from any brand if the station owner is dishonest. Before all the Amoco stations disappeared, I had always found them reliable, with the notable exception of one station in Somerset, PA, where the guy watered down the gas (we wound up stuck overnight because, after filling up, we stopped to eat and then my Accord wouldn't start).

In my 00TL, I was completely out of gas, I filled up full at Mobile with 93, 1.5 blocks later my engine began to insanely misfire and shutting off. Only two cylinders some how worked, so I pulled in to my mechanic shop, which luckily was down a hill, so I slowly made it there... The misfire was insane, as I felt like my engine was about to explode and just fall the eff out, it even tore my engine mounts...
Result... Water/contaminants in the gas... I spent of 2K repairing the damage...
I tried to sue the effen place, but I was told that I should of called the cops once the engine began misfiring... If I would of done that, the cops would of told me to go f myself. So I couldn't sue. A month later, the gas station was closed. Apparently, the pattern of stalled cars finally got noticed.
This is why I don't mess around with gas stations that I do not know, or any gas station that looks like a rundown station.

On my experience Bp and Shell are both good!!!I also use Mobil...
Never use Speedway!!! i got bad experience with this...You will only see the diference of these gas on old cars or old engines...When i used Speedway and other brands i noticed that my sprakplugs are turning black due to badburn or dirty gas but when i started using BP and shell my sprakplug looks ok on every 3,000 miles...

I switched from Shell to BP when the local shell stations started charging a disproportionate amount for premium.
That is the gasoline cost structure I approve of... the shells started bumping up the mid grade by $0.13 and the premium by $0.26 which pissed me off. Anyway, this whole shell vs. bp or mid-grade vs. premium debate has been posted, reposted, and reposted again many times. Bottom line: I don't think there is a quantitative analytical method a laymen can use to say that one company's gas is better than another's. You'll find many MANY unsubstantiated opinions on the topic, but no hard data to back them up.
Run you car with 3 or 4 tanks from shell, calculate your mileage (divide miles driven by gallons used, do NOT use the on board computer which is not very accurate in my experience). Switch to another brand for 3-4 tanks and repeat. Assuming you're sticking to your usual route, outside temperature is more or less constant, driving habits constant, traffic flow, etc. etc. etc.
That's about as good as you can do I'm afraid.
Code:
Regular = $x/gal Mid grade = $x + 0.10/gal Premium =$x +0.20/gal

I haven't used BP much. The only BP in my area is managed by a Business School dropout who always charges $0.20 more than the Texaco and Sunoco across the street. The local Shell closed down for some unknown reason. The only Shells I know of are off of my common commute.

says VtecTL without absolutely any experience in molecular chemistry..
Anyone else feels like leaving a definitive blunt opinion?
For the last time, gas is not created equal... It's a volume which s considerably affected from refining to delivery processes.
