Default Alcohol free 87 octane...

Just discovered a gas station featuring no-alcohol gas, but at 87 octane only. Should I pass? Current fill is Chevron 91 octane with 10% alcohol.

What do you guys think?

Not unless you want the engine to retard the **** out of the timing.

The 10% Ethanol content won't hurt your car. 87 probably will. Stick with the 91.

All the above, plus crappy gas mileage. 87 octane, in a turbocharged engine (tuned for 91 minimum), under good boost, would be pretty dangerous.

Two places in Boise that carry ethanol-free 91:

If there was any chance of a pipeline being approved (LOL!) we could pump down corn juice free 91 octane or 94 with 5%........up here we all eschew any amount of ethanol even for the extra 3 points.

I'm a bit perplexed. In CA it shows 6 or so places in Norcal that are alcohol free and comments you must sign a waiver it is for off road use and have a tank to carry it home in. Truly 100% ethanol free?

But then I look at a state like Nebraska and there are dozens that claim ethanol free even in the 92-93 range. Are those really 100% ethanol free or just under 9% ethanol. Nebraska usually labels a 89 octane that is cheaper than the 87 that has ethanol and i think it's >10% ethanol - that doesn't mean the others are ethanol free right?

I guess what I'm saying is I think the web listings are misleading.

I like putting premium fluids in my car if possible. It's too bad Sunoco doesn't make a street legal <9% ethanol product. It's all mental I know. Maybe Sears Point has some unleaded low ethanol I can sneak off with.

100% Ethanol-free fuels may be illegal for use in road vehicles in California. I'd have to look into it, but I know the state of CA hates cars.

Inject some water to that sucker, you will lift your octane rating by at least four points.

Compatibility of E10 fuel with Porsche vintage cars and recent classics
Verify your classic car‘s compatibility of E10 fuel with the help of our overview

E10 is a fuel which contains a higher proportion of ethanol than previous petrol formulations. The “E” stands for ethanol. The number “10” indicates that the fuel contains up to 10% ethanol. Previously the proportion of ethanol in petrol was up to 5%.

E10 fuels are suitable for refuelling and thus for running all Porsche vehicles as of year of construction 1996. Specifically, the Boxster (model year 1997) and Carrera (model year 1998) models onwards.

These new fuels, which can include up to 10% ethanol in the future in accordance with new statutory regulations, can be used in all new Porsche vehicles without any problems.

The fuel types Regular E10 (91 RON) and Unleaded E10 (95 RON) are not suitable for use in the following Porsche vehicle types:

Type Year of construction
356 1950-65
911 1965-89
912 1965-69; 1976
964 1989-94
993 1994-98
959 1988-89
914 1970-77
924 1976-88
944 1981-91
968 1991-95
928 1977-95

These Porsche vehicles may not be run on E10 fuel. As an alternative, Super unleaded (98 RON) can be used. With a maximum bioethanol content of 5% (E5 fuel), Super unleaded is compatible with these vehicles.

Please contact your nearest Porsche Centre for more detailed information.

Click on the "details" link for the stations you're interested in, to get more info. I drive a bit out of my way at times to get gas for both cars, here --

If in doubt, ask the clerk, or call the owner if you are concerned. Or you can just test the gas yourself --

Interesting. That fuel-testers.com link shows that MANY states by law require an ethanol label if it is above 1%. Interesting so many states in the grain belt require labels.
