Does anybody know if it is possible to find higher octane than 91 in California at all? Preferably in the Bay Area - or is the 91-octane premium definition a state-wide thing?

Thanks,
Lars - just north of San Fran

I always use 94 or 91 if I can not find 94 but I never have, or will use 87.

No save here,Flavor 987s I am not (jcb 986), I am jbs 986, there are some cars that you can run 87 Oct., Are Boxsters use a higher Oct, because are motors are high compression motors, lower Oct, will cause "Engine knock" not a good thing for any Engine. let alone the M96.

I figure if you're in a pinch or in some backwater place where they don't have the octane you need, I imagine the car will run on 87, but first chance you get to throw the proper octane in, it should be done.

The way I see it, and read it in some cars' owner's manuals, most modern cars that are meant to run on a higher octane can run on something lower, though it is not recommended for regular use because over time that will cause damage. So again, in a pinch, you do what you have to do rather than be marooned in the middle of nowhere, and simply fill your tank with something higher when you can.

While not verbatim, I'm pretty sure our manuals say something along the lines of "use premium fuel, or the highest octane fuel available to you". Around my neck of the woods that is 93, though some places will only have 91, and there's not many, if any, stations left around here that aren't using ethanol additives, so I have to bite the bullet on that one. But I'm using the highest octane available to me, 93. If I end up on fumes in some random place like Yellville, Ark., and they only have up to 89...well, that'll have to do until I can get to a station with something proper.

Take a Jeep Liberty, for example. The manual essentially says the car can be run regularly on 87 without any issues, but if you're going to be doing any towing, that will require optimum performance from the engine, so they recommend using 89 for that. By the same token, you could also fill up on 89 regularly and be just as well.

If someone's looking to cut their fuel costs and seeing if they can live on commuting or joyriding on 87, well they picked the wrong car for that...if it could've been run on 87 regularly they would've built it around being able to do that. A Corolla the Boxster is not, so you have to give a premium car premium fuel.

No offense meant to anyone who happens to be from or near/around Yellville, just picked a random place.

So to stir the pot a bit more, which would be better?

91 octane
or
93 octane with 10% ethanol

We only had 91 around here but saw the 93 blend recently.

Trying to save a couple of bucks by filling up with lower octane doesn't work for high(er) performance cars. The ECU will just adapt the mixture so that the engine power stays the same. Lower octane will lead to lower mileage. We've been driving Saabs for many years and decided that the highest octane will cost the same in the long run and results in a smoother engine.

You will get better MPG's with the 91 octane (no ethanol) vs the 93 (with 10% ethanol). Did this experiment last year. 93 is probably still the best bet. 93 pure gas (no ethanol) is ideal. It is very easy to find in places like Wisconsin, maybe due to all of the RV's and boaters.

I did this experiment with my previous car (toyota solara). The car recommends 91 octane (but can take 87 with some engine output reduction/increase fuel consumption per owners manual). I put 91 un-oxygenated fuel when I was in Minnesota and I put 93 with ethanol when I moved to MI. No noticeable power difference, but 91 with no ethanol returns at least 2-3 MPG better on highway.

You can get race gas, 100oct unleaded but it is about $8.50/gal. I ran a 100/91 blend for a while on track days but now just run 91 pump gas. In Calif we are "special" so we get "special" gas formulations in an attempt to improve emissions. Welcome to the Golden state.
