If you have water in your tank it isn't from the gasoline. You could possibly be getting water in around the cap or some other way. Car washes do not cause gas to have water in it and the majority of all tanks now are fiberglas underground tanks.

nope - but I do avoid stations with a car wash since I found water in my tank.

Some gas station owners are sometime dishonest. Some have been known to add a little water into gas tanks.

As far as gas goes, the biggest difference is if it contains ethanol or not.

Diesel varies based on temperature and blends made for freezing temps.

Other than that, each region is going to have fairly similar gas as it all comes out of basically the same distirbution points and only the additives vary which honestly do not make that much of a difference.

Banjoe:

"I've experienced tremendous (20%) mileage variations between fuel supplies depending on the season and location. After burning winter diesel in Manitoba, we had the chance to run some nice Florida fuel through the Golf and experienced extended mileage. I'm thinking it's because of the cold weather blends or maybe Florida diesel is just that much better but there are variations out there."

If you're talking about different blends of fuel and different driving conditions (be it altitude or something else), or driving differently (be it speed, open highway versus crowded urban driving, etc.), as well as differences between winter-summer/California-Winnipeg mandated blends, you're obviously going to experience different results, even if all the driving style and/or conditions are identical.

You're somewhat saying "I buy Kentucky Fried Chicken in Winnipeg and, you know it doesn't taste anything like mom's chicken pot pie...Aren't they both made from the same chickens?" Yes...and no.

i would like to think not, but i guess there are better gas stations and i just dont know where. gas is only 80% gas and 20% fillers like oxygen, cat tails, sand, chili, and who knows what else. we are getting ripped off on all counts.

I started a post http://www.dallasgasprices.com/Forum_MSG.aspx?master=&category=1056&topic=491716&page_no=1&FAV=N

There are several replies there that describes how gasoline is distributed. In a city, all gasoline come from essentially the same refinery. The difference is the additives each brand puts in. So the mileage should not differ. What is different is the amount of detergent that is added to the base refined gasoline like the top tier gas station.

I prefer to fill from gasoline stations that is certified as Top Tier Gasoline. They can be found at http://www.toptiergas.com/retailers.html

They include several name brand and some smaller ones.

They are endorsed by six car companies GM, Honda, Toyota, Mercedes, VW and Audi. They have additives that are higher than the EPA minimum, which will keep the engine cleaner and better in the long run.

I have read about this fuel mileage differential several times on GB forums. In nearly 40 years of driving I have never conclusively seen it first hand.

I do track purchases, and I am trying to find such a nugget in the data - no luck so far.

"do u agree"?

No, I don't agree. The slight difference that you might think you notice is a result of slightly different driving conditions, be it roads, traffic, manner of driving.

But, if you're going to tell people that you "paid close attention to my mileage when purchasing gas at a specific gas supply chain..." and "then comparing it to others...", you might want to tell people how you conducted your formal testing, what fuel brands you tested, and what your results were.

But, a further but, can you tell us what you mean by "purchasing gas at a specific gas supply chain"?

What is a "gas supply chain?

It's probably naive of me to ask, but have you posted gas prices for the various brands of gas you've bought, perhaps gas prices from the "specific gas supply chain" you're talking about, or the others you compared it to?

I agree -- ethanol free fuel works better in my car than E10 ...

I get better mileage when I purchase ethanol free gasoline in Oklahoma than the 10% ethanol blend I purchase in TX.

Before someone comes on here and says this, let me say this. ALL REGULAR GASOLINE IS THE SAME when it comes out of the refinery, that's why different brands sell gas to eachother. Then each brand adds its own mix of additives (detergents for the most part) before the gas is delivered to a retail location. The gasoline is the same, it's the additives that make a difference.

Different engines will respond differently to the additives, and never in a good way. These additives are there to clean your engine up a little bit, but some of them actually interfere with proper combustion or actually clog things up inside. One of my vehicles runs exactly the same (mileage-wise) on Esso, Husky or no-name cheap gas, but runs extremely poorly on Petro-Canada and Shell. I guess she really doesn't like the crap Shell and P-Can add to their gas, because I need a full-tank of something else in order to clean their gunk out of my engine. This is one case where no additives are actually better then some.

I haven't consecutively experienced this, but sometimes you get what you pay for.
