Alhtough, in theory, the car is tuned for 91 AKI, so it should be fine. Also, I've seen no clear evidence of non-California cars putting down more power as a result of access to the slightly higher octane.

93 is preferable, but really 91 should be okay.

just not cali 91 because it's oxygenated or even 93 with 10% ethanol. I only want gasoline, ferosene, toluene, and MMT in my fuel, maybe a little isopropyl alcohol in winter.

Skip lunch and use that fund for your premium gas. Sounds like you're back in highschool
Lol. Stay young.

What the Owner's Manual say?... PREMIUM

Other than that the owner is looking for problems.

I am facing a hard choice as well. The ESSO stations here in Germany all swapped to E10. I can still get premium 93 but what would be the long term issues of using E10 rated at 95 oct?

Under stock set up you only need 91. I'm not sure why other people are saying they run 93. Why would you need anything higher? You only need it if the compression was changed through modification on your engine. Running higher octane would be throwing your money. Please correct me otherwise.

On the east coast it's somewhat rare to find stations with 91. We usually offer 87, 89, and 93.

i also go to sunoco and they have 91 and 93. i figure theres such a small difference (2-3 cents) i might as well just go 93

gbrettin · 03-07-2011, 11:18 AM

Yeah, most gas stations here offer only 93. The only exception to this is Sunoco which offer 87 - 93. I typically goto Sunoco.

I will need to take a second look at the prices but I thought there was more of a 10 cent price difference between 91 and 93. I drive 110mi per day in the Z at least so it adds up. I'm not crying about the prices either. I knew what I was going to get when I bought the car.

i guess it depends where you are. i have a 10 mile commute. and around here the difference is very small. the big gap is 89-91 i think

10 cents x 18 gallons (usual fillup amount) = $1.80

who cares...

This guy's numbers are gonna add up pretty quickly at 110 miles a day. That's a fill up every 3 or 4 days assuming he's staying out of the fun pedal and maximizing his fuel economy. Assuming two fillups a week (which is what my fun pedal usage would require), he'd save $187.20 a year by using 91 vs. 93.
Certainly not a make or break it figure, but if 91 works just fine, why not pocket the savings?

if 91 works fine and $187.20 is a big deal, i suppose that is a good option~...

but that could also mean $187.20 less consumed tacos and burgers which would be cheaper considering medical visits and bills. lol

are you REALLY saving money by doing this overall? i dont know... i doubt it. people think they're saving nickles and dimes here and there but still in the red often do to worse habits.
