Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

16 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

1 acknowledgements have no verified action link; they do not establish a repair result.

Outcome without a verified action link

At $2.80/gal, it's certainly still not too bad.

POST 1 / ORIGINAL POSTEROriginal post

I live in a town that doesn't have anything higher than 92 octane (BP station). That's pretty much my default station given that Porsche recommends 93. So all is well until the wife bought a whole bunch (i.e. a stack or a sh*t load as some would call it) of Shell gas cards -- she found a deal where they can be purchased @ 20% off. Well unlike Texas where I spent a good number of year, all the Shell stations here pump 91 octane only. Q: shall I even bother using these Shell *prepaid* gas cards on my 996? -WKL

POST 2Original post

In CA, the BEST you can get is 91 and mine still runs fine.

POST 4Original post

In Russia 98 octane is recommended by the manual and dealers, same in Europe i think. It is quite weird that they have different reccomendations for EU and US. Alex

POST 5Original post

US has different octane rating than ROW. Where to get the shell card at discount? I want some....

POST 6Original post

Yeah, seriously, I live in NYC and I'll drive to Texas to save 20% on gas....

POST 7Original post

Pretty much everywhere but the US (and maybe Canada, I forget) uses RON. The US uses (RON+MON)/2. Your 98 is like our 93.

POST 8Original post

The car will detune itself for the lower octane, so there will be no dire consequences.

POST 9Original post

Palting is correct. I'm able to get Sunoco GT (100 unleaded) at a pump and mix in 5 gallons for every 10 of 91 to get a tank octane of 94. Subjectively, the car feels stronger, particularly in the higher RPM ranges.

POST 10Original post

Europe has a different way of measuring octane UK - RON USA - RON + MON / 2

POST 11Original post

Same here in Vegas. We import that crappy California gas

POST 12Original post

Lucky us Texans, living in the energy capital of the U.S. 93-octane gas is readily available even at your neighborhood convenience store pump stations here in Houston. At $2.80/gal, it's certainly still not too bad.

POST 13Original post

I just paid $2.79 for 93 octane at the local marina yesterday. Typically, the marina gas is much more expensive. I was pleasantly suprised and bought more than I needed! We ran 72-76 mph in the beautiful weather, it was great!

POST 14Original post

Canada does use the RON system. Standard "high test" gas is 91 here, and you can get 92 in a few places, and 94 at Sunoco. That's what I use and it always works well. I've run it since I got the car, so I can't comment on how and if it feels different.

POST 15 / ORIGINAL POSTEROriginal post

Hey gang, Okay...here is what the wife did (didn't know the procedures until now that I ask -- hell, only professional housewives can do this kind of stuff): ** DISCLAIMER -- THIS NOT AN ENDORSEMENT ** Go to: https://www.membershipme.com/giftcar...g%20essentials - Sign up "shopping essentials" (monthly membership $14.95) - Purchase Walgreen gift cards (apparently you can also buy gift cards from Target, Lowes, Amazon.com etc. Max $500 from each company) - Purchase Shell gas cards from the local Walgreen's using Walgreen gift cards - Net-Net: you basically pay for full amount and receive a 20% rebate @ end of month * You can cancel the membership anytime but make sure the rebate arrives first * -WKL '02 C2

POST 16Original post

Since I only fill up about twice a month, the 20% discount on fuel at Shell would be a wash for me. I pay about 36 bucks a fillup, FTR.
