Best gas?
 

I usually pump Chevron Plus for my car (mazda3s 4dr) but i guess Shell bought out all the Chevrons in the area and i dont know what other gases are good to use



sorry if its a stupid question... but oh well

The cheapest.....and before it's asked, please run the recommended octane for your car also...higher octane gas is a big waste unless your car was designed to run on it

yes i know that. im not looking for the cheapest gas, but the best quality gas for my car

I Like sunoco personally.

uumm..
unless Im mistaken.
isnt it near impossible to tell best gas for an area?
considering different companies are in different places?

lol. true...wasnt thinking about that...



i guess it wouldnt hurt to see other people's opinion though

nope. a little opinion never hurt no body.

Well, I've always thought that Sunoco was the crappiest. But it's what I buy 90% of the time because it's close to my house. And I know everyone who works there (including the mechanic who will hopefully pass inspection on my car this year even with the header...)
I honestly couldn't tell you if any gas is bad consistently in my area.

It really is hard to tell how good the gas is chemically-speaking. Some places will try to rip you off with watered-down gas or the like, especially the REALLY cheap places! Me personally, I prefer a newer station such as this brand new Shell that opened up near Clear Springs. Those newer station's (albeit with a quality name, i.e., shell, exxon, etc.) filters are brand new and not filled with clutter. So the gas pumps quicker and just like a clogged oil filter, it does not allow the passage of this clutter.

Here in tx, you'll notice a green circular seal which shows the last time the pump was inspected, month and year. I've noticed the stations with older "inspection stickers" the flow is slower so you can guess what that could indicate IMHO.

^^^damn, I never thought of that.

Yeah few of us do. My brother works at an oil change place like Jiffy Lube (but NOT like jiffy lube) and he told me that. Now i use that everywhere i go to get gas. You know, around here anyway...

watered down gas = an exxon around here.

I forgot what the place is I get gas at...
somethinga bout a kangaroo, haha

For some reason I find that SHELL gas, 87, makes my car run rougher, the idle is rougher enough that you can really notice, while McEwens gas or Petro-Canada is fine with the car. Would it have anything to do with the composition of the gassoline or the detergents they use??? For me Shell has the cheapest (by price) gas but with the odd idle when i tanked up there I stopped using it.

i thought oil and water don't mix? wouldn't that apply to gasoline too? the water doesn't separate from the oil?

i've started to keep track of my gas mileage. i'll fill up with a tank here and calculate my mpg, and fill up with a tank somewhere else and keep track of the results. i've found my car works better at certain gas stations and stuck with those ones. almost all gasolines have some kind of detergent in it (V-power for example), some more than others, but not all cars benefit from the extra cleaning agents. i've seen a few toyotas actually get better mileage on those fuels with extra detergents. ultimately driving habits are what will throw off my mpg results. one day i'll be driving faster than usual cuz i'm late or something, other days i'm the slowest granny on the road.

Shell is supposed to use some sort of gas/fuel injector/valve header cleaner mix in all of it's octane gases, and just more of it in their higher octane V-power stuff. I'm sure the mix is a pretty dilute one.. but it's better than nothing I suppose.
