Like the title says, what do you choose? I stick with the non-ethanol gas, even though they have dropped it down from the 91 octane it was. It's been a while since I used the corn gas, but I seem to remember that seat-of-pants feel was better and mileage slightly better with real gas. Thoughts?

Non-Ethanol for me!

In BC Chevron sells ethanol-free 94.

I would also use the ethanol free stuff. You have knock sensors in the 964 which should prevent pinging all the way down to 87 octane. The numerous rubber hoses, fuel pump, and injector seals in the 964 were not designed to hold up against ethanol. That being said, I have seen the most detriment occur to cars that sit, rather than those that are driven. You could also consider an octane booster at each fill up.

if you don't mind the pain in the ***, use the eth free and then add torco to boost the octane.

CA gas is Fuchsed up! No choice whatsoever for pump gas in Socal Thanks again politicians, and big oil!

Its not big oil! Its big Ag! Exxon Mobil has no interest in selling corn.

92 with ethanol, hands down.

These cars NEED a minimal octane to make power and 90 isn't enough. You really don't want to use any octane boosters and the effects of ethanol can be ameliorated by judicious use of (blue) Stabil.

Steve,

By blue Stabil, you mean the marine Stabil? Great that we have to add a product to counter-act a product that is put in. Makes me want to go on a corn-free diet. Well, except for bourbon...

WBYonder, if you're near Pasco and Richland there are a bunch of choices for non-Ethanol 92, no?

Exactly...Governmental subsidization based on biased research underwritten by Big Ag and promoted by the Big Ag lobby resulting in an inferior product that is sold to the public at prices not justified by the product's low quality....It's the 'Murican way!

I have local access to 94, alebit with ethanol. It's my choice for spirited summer driving and definitely for track.

If I'm just tooling around on the highway though, and for winter storage - back to Shell V Power 91 with no ethanol.

Kinda the best you can do under the circumstances, I think.

90 is marginal and you are relying on the knock sensors to do their thing. Too much heat, too much load, a bad batch of fuel that's sub the listed octane and you could have an issue that you will not realize until it is too late.

Cheers

MC,

The locations on that site are either commercial (I don't use enough fuel for them) or in the case of the Conoco stations, inaccurate. They list the Conoco stations at 91, which they used to be, but they lately have had 90 octane, and charge dearly for it. I think I'm going to give Steve's recommendation of 92 and blue Stabil a go.

Matt Lane

I have also heard about the Marine Stabil as a potential remediation - makes a lot of sense in those applications with the high humidity and and the hydroscopic propensity of the cornohol to mix with the water.

PS - Hard to go wrong asking WWSWD... ("What Would Steve Weiner Do?")

Yessir,.. precisely!

This has been SOP since Congress mandated dropping MTBE for Ethanol.
