How to get the most gas for your money!
Though it would be a good idea to put these tips and tricks i learned from a friend a while back on how to get the most gas for your money, I don't know how much you guys are paying but in NY were still on the 4.00$ for 93 octane.
1.Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening…your gallon is not exactly a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role. Any one (1) degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.
2.When you’re filling up do not squeeze the trigger of the nozzle to a fast mode. If you look you will see that the trigger has three (3) stages: low, middle, and high. In slow mode you should be pumping on low speed, thereby minimizing the vapors that are created while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some other liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you’re getting less worth for your money.
3.One of the most important tips is to fill up when your gas tank is HALF FULL or HALF EMPTY. The reason for this is, the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation.
4.Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up, most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom. Hope this will help you get the most value for your money.

Thx Andystyle,
I will give it a go
I have used Shell 'V' power from day one. My exhaust tips are free of any deposits could it be the fuel?

1. Is is alright to mix two different brands of gas with the same octane level? Ie. BP's Ultimate 93 and Shell V-Plus
2. What about mixing two different brands of gas with different octane level? Ie. BP's Ultimate 93 and Shell's regular.
I heard that gas with different octane level are not supposed to be mixed.
Thanks.

Atlanta is having gas crisis. I was running really low on fuel, and all the gas stations have is regular. So I put in 2 galons of regular 
then after a few days, I mixed the regular with premium.

You'll be ok. An emergency situation like that is fine, or even an accident if someone ever put some by accident it would end up ok I'm sure.

But I use premium Shell in our Jetta 2.0t, which recommends premium, and the tips will get deposits after 1 day of driving.

I bought my C300 three weeks ago and with the gas shortage in Atlanta, I had to put no-name 87 octane in for the first fill up(either that or make like Fred Flinstone)...almost made me cry. Anyhow, added a bottle of octane boost and drove easy(no pinging). Just seemed like a bad way to begin my first Mercedes experience.
Once the stations get caught back up, I will be a BP/Amoco user.

Over the recent years, I have been consistently impressed by the good quality of Costco's house brand of various products (Kirkland). Tells me something about the company's quality standards. Combined with the huge volume of business, what I've concluded is that Costco premium gas is likely also high quality, fresh, and clean, as those underground tanks are all fairly new and constantly being drained and refilled. We use Costco premium in both MBs and regular in the Jeep and all is well.
But, they do run the pumps faster than most other gas stations, confirmed by Costco, so to prevent splashback, only use the slowest automatic setting on the handle.

I use Esso 95 because of military contracts, but Shell V-Power is definitely recommendable.
Here's an interesting article about taking the different brands to the Dyno.
EDIT: Carlsson also recommended blending 100 grade fuel into the tank to achieve better high end performance. I'm pretty sure you could fill the entire tank with it, but the costs wouldn't justify the results for most driving. Octane only measures the stability of the combustion at high pressure and temperature so at face value it won't hurt your car.

Hey Glen, what do you think of this homebrew octane booster?

That's a good point and seems to apply to name brand stations as well. I see a variety of local oil company trucks with no brand affiliation pulling up to refill our local Sunoco and Shell stations...no hint of Sunoco or Shell anywhere on them. I guess it's best to get to know your local station and stick with that good one when you can.

Any major tier one brand that doesn't use ethanol.
Why?
1. Ethanol = lower mileage
2. For Direct Injection engines ethanol can add to the carbon buildup.
In my opinion Shell is probably the best gasoline.

One of my good friends is a 15 years Chemical Engineering veteran at Chevron. He works on the design/testing of the Techron agent. Although he could very well be "drinking the chevron kool-aid" he says that NOTHING compares to the positive attributes of Techron. Closest second is Shell V-Power. I believe him

To summarize, your car is designed to run on premium. If you run regular, you will get less MPG then if you filled up with premium. So, even though you save $3 or $4 at the pump, you break even ( or worse ) when it comes to MPG.
Think about it...

I use no name regular
I use no name regular and the sign on the pump usually states it contains 10% ethanol, have been using since new and I have absolutely zero problems and get as high as 29 MPG on long trips using cruise control.
I use any brand usually grocery store chain (Kroger), and sometime Sheetz, and when on a long trip away from home base, whatever I can find thats cheap, in it goes!
