How many people use Audi recommended gas stations?

[linet90]

When I got my A4 Audi mailed booklet out with a much of Audi history, Magazine, and Accessories book. One other thing I got was a card listing all of Audi approved gas stations.... anyone use them?

[Ryan_T]

I use Shell only. Or Sunoco if I need 94.

[UmIsThisThingOn]

I only use approved gas.

I only use the ones I can find locally, but it makes wonder why Sunoco in the US isn't on the list.

[Speedybrit]

I would have followed their recommended gas stations if i didn't see the same gas tanker deliver gas to a sunoco and texaco right across the street from each other one day. Made me wonder whos gas really is inside the tanks under gas station. Unless they are owned by the same company??

[rxer311]

I use Turkey hill because I have one 1/2 mile from my house.

[Ryan_T]

Sunoco is the only one with 94 in Canada. PetroCanada recently bought them and now they have the Ultra94 too. But everybody else tops at 91.

here in BC chevron carries 94...
but it's expensive so i use shell 91

[Ryan_T]

Oh ok. I've only been in BC once, a long time ago. I was speaking from Ontario/Quebec.

[linet90]

I used to use Mobile till I found out about shell, I’m sure it makes a big difference. Does anyone know who carries 95?

[Jacon]

Shell only and Conoco when I'm in a pinch

[cazeluf]

I used Phillips 66 a lot of the time before I got my 2010 A4, but I use it almost exclusively now. It's hard to say if there is anything to the whole Top Tier Gas deal, and in any case, since our engines are direct-injected, the valve train components are not getting washed by whatever detergents they're putting in the gas. But, it's pretty easy for me to just stick with Phillips.

[SharkB8]

I don't know if it's all in my head, but I swear my car gets better MPG and power with Shell than anything else.

[A5MD]

Just did my first fill up using Shell. Seems like Shell is the most popular here as well as the Bimmer forums.

[Ynnekdude]

Shell babyyy. Also noticed I get better mpg with 93 as opposed to 91.

[ikotua]

In Cy, you can't get less than 95. I fill up 98, 100 at times.

[MYFASTA4]

only use Chevron here

[mangust]

Anybody knows why Sunoco Canada is on the list, while Sunoco US (which is what I mostly use) is not?

[Comp4k]

i use shell and chevron.

[2SwiFt29]

Not a lot of Shells around the area as there was before. Mainly 76, Chevron, Mobil and ARCO. However, I only stick with either Chevron or 76.

[Brrman]

Anyone know what Costco uses for their gas? I use their 93.

[Yahdatshim]

Since we are on the octane subject... I'm here in mass and the highest we get is 92... Anyone here ever use octane boosters...

Also I'm a shell/mobil guy...!

[JetBlue]

Shell and Chevron for me. Unfortunately Kalifornia only has 91.

Knowing Costco it is probably top tier gas just like their private labeled Vodka.

[Brrman]

hmm - what vodka do they use for their private label? I have never bought their vodka, but I drink KetelOne and Grey Goose.

[Calbee]

anyone from canada know if husky is any good? i only heard my dealer said to use 91 so isit alright if i use husky?

[hoppy6698]

Shell, almost solely, unless I'm stuck in BFE and don't have a choice.

[VRockzNY]

Oh woww I use BP since it's right down the block from me....I thought it was supposed to be pretty above average. There's a Shell on the way back from school I guess I'll start filling-up there.

[T0XiK]

is the octane measurements the same world wide? here in china we have 93 and 97 i always use 97 but now i am wondering if i should just use 93

[mart242]

Does anyone here have problems with some of the pumps? At some pump (my local sunoco that sells 93 fuel), I can never fill the car properly because it stops all the time (it "clicks", as if the tank was full) so I either have to fill the car really slowly or try to find the sweet spot of where to put the hose / filler so that it doesn't do it but that doesn't seem to be an easy feat.. I pretty much gave up on 93 and put the 91 from petro-canada.



Toxik: Octane is calculated differently in north america vs rest of the world.

I hate when that happens. I feel like a moron if I stay and try to fill it by clicking the pump a hundred times, but who wants to drive to another gas station without having gotten any gas?

On topic, I noticed that some Shells around here say "no ethanol" while others say "up to 10% ethanol." It makes me wonder how much gas differs from one station to the next, whether they have the same name or not. Yet, I still buy Shell for the most part (no ethanol, of course). It still annoys me though, buying Mid East oil, but that's another issue.

[Wildcat216]

btw, I love how Turkey Hill is on the list but Sunoco and BP are not. Thought that was funny when the dealer first gave me that list.

[tommydrum]

I'm nearly certain that the U.S. supplies are not on the list because they are diluted with corn juice. I doubt that Canada has to fulfill that obligation since I don't think there's too much corn growing up there, and you're not obligated to support our corn crops here in the U.S. If Canada can cleanly tap the oil from the Alberta tar sands, that will be a big win for everyone in North America. Then we can focus on feeding corn to people and cows, instead of our cars.

I did that a few times.. I'm sure that I looked like a cheap moron since I put only $4 of gas in an Audi...

[carlos19143]

Shell 93 octane.

[B_Boy]

i always use shell but since the gas price for 93 is like $3.40 here (at shell) i said fuck that i got a costco that sells 93 for $3.08 and i believe they use BP or something.

Audi Recommended Gasoline Retailers and Recommended Octane are two very different things and I did a quick explanation on them both since the thread was talking about recommended gas but all the posts ended up being about octane and not why you use the below companies gas.


I know this is a old thread but just in case anyone comes across it like i did they will leave with all the correct information. Audi's Top Tier Gasoline is recommended for the adatives and other detergents that clean out the gunk and deposits that build up inside of the engine.

http://www.toptiergas.com/
Why TOP TIER

The intention of the TOP TIER Detergent Gasoline standards is to create a winning situation for gasoline retailers, auto manufacturers and drivers. Currently, many gasoline retailers provide fuels with lower-quality additive packages that can build up deposits on fuel injectors and on intake valves. Others can build up deposits in combustion chambers and may lead to intake valve sticking. These lower levels of additives can have negative impacts on engine performance and vehicle responsiveness.

TOP TIER Gasoline Retailers:

USA
76 Stations
Aloha Petroleum
Conoco
CountryMark
Entec Stations
Exxon
Holiday Stationstores, Inc.
Kwik Trip / Kwik Star
MFA Oil Co.
Mileage Stations
Mobil
Phillips 66
Quik Trip
Rebel Oil
Road Ranger
Severson Oil
Shell
Texaco
The Somerset Refinery, Inc.
Tri-Par Oil Co.
U.S. Oil

Octane at any USA gas station is measured the same but not all have the same additives and detergents to keep you fuel system and engine clean and gunk free but you can also buy the additive at those gas stations or a Audi dealer and add it every oil change or every service interval which Audi recommends which will do the same thing as Chevron, Exxon, Texaco and Shell except because of the longer interval you are adding a more concentrate version directly to one fuel tank of gas which is recommend to not fuel back up to you have run 95% of that tank through you cars system

Now octane controls the combustion since we have removed lead from fuels way back when. Fuel is more combustible when the octane is lower and more stable when higher levels are in the fuel. Gasoline can com-bust just from pressure not needing spark. this is why all car makes and models have different recommended fuel along with Min/Max octane levels which are in your owners manual Audi usually says in manual and on the inside of your fuel door that 87 octane is the minimum because of there compression ratio (high compression ratio can cause fuel to com-bust / ignite from pressure then spark ignition happens late causing spark knock which is bad for piston heads and cylinders). But most engines fix that by retarding the timing causing the engine not to run at peak performance but cause no permanent harm just temporary stuff like less power and less fuel efficiency. Now if you car only calls for 87 then your just throwing you money away by putting a higher octane in you vehicle it does nothing for performance or fuel economy on stalk cars unless the car was designed to run on higher octane from the manufacturer.

There are 3 different ways to measure Octane.

In most countries, including Australia and all of those in Europe, the "headline" octane rating shown on the pump is the RON (Research Octane Number) is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane. 600rpm test engine.

(Motor Octane Number) (MON), or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load, as it is determined at 900 rpm engine speed, instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON, however there is no direct link between RON and MON. Normally, fuel specifications require both a minimum RON and a minimum MON

Canada, the United States and some other countries, like Brazil, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI, and often written on pumps as (R+M)/2). It may also sometimes be called the Pump Octane Number

Difference between RON and AKI
Because of the 8 to 10 point difference noted above, the octane rating shown in Canada and the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel.

So the United States and Canada put the same exact fuels through a higher stress test using (RON+MON)/2 which is a average of the two called the AKI showing a lower octane but is 4 to 5points higher than what is listed on USA service stations which give the below numbers the same equivalent as European RON method.

USA/Canada= Europe/Asia
87 = 91/92
88 = 92/93
89 = 93/94
90 = 94/95
91 = 95/96
93 = 97/98
Now any fuel getting closer to 105 to 110 octane usually has lead in it that will cause damage to the catalytic converter which is in all newer model cars unless it is a track car which usually are not required to have one. For my Audi I looked up the price so i could just point this out $335 for after market OEM replacement to $950 for the Audi OEM before instillation.

I use Sunoco 91 and Audi fuel additive every 3,000 miles. Exxon and Shell are 30 cents more expensive per gallon, not worth it.

[ArubaBlue32]

im in boston, and there's a ton of places that have 93, and 2 sonocos that carry 98

[eyrah]

SHELL! always, and is anyone else pissed off about paying $4.39 a gallon?! i hate california
