93 only.

I've heard numerous analysis for both sides. Some swear it does not do any better some and some swear it is an amazing difference in power and helps for the life of the engine (Better combustion etc...).

But just because the Porsche says so in the manual and the gas cap I put 93.

They must know better...

I've never put in anything but 93, but as others said some 91 won't hurt - especially in highway cruise mode. With knock sensors there is little chance of ping or pre-detonation anyway.

I've also come to fear that with high gas prices some cheaper gasoline companies are cutting additives to offer lower prices. Check out this website for Top Tier brands.

91 is the highest available where I am, so that is what I put. When I'm in Chicago, I put 93 in my (other) car.

I've always used 93 in my Firehawk and will continue to do so. I will also only use 93 in the Boxster. It's only a couple of cents a gallon. Since it looks like crude prices are coming down, I expect gas prices will follow shortly.

Regular was down to $3.81 around Jacksonville, today.
I Will only use 93 becasue I have proven, beyond a doubt with my DD that I lose money by going to mid-grade. I won't try it in the Box. If I can't afford to run premium in the Box, I can't afford to drive it anyway.
Funny how the demonrats are trying to maintain the lie that drilling for more oil won't affect the price, yet as America does no more than demand drilling for our own oil, the price drops.
How'd everyone like the big F*ck You Nancy Pelosi gave the whole country Friday? :troll:

Got a link? I hadn't heard. Actually, maybe PM me as that's quite OT.

Are you asking just for 986 or 987 too? I use whatever the highest is, don't know if it's always 93.

The big F U Pelosi gave us all was shutting down the congress, turning off the lights and cameras and taking off, instead of having a debate or vote on the energy plan. As of Yesterday, the 30, or so, republicans are still there calling on the democrats to come back and do something.
Now, I have a problem with the republicans doing nothing when they had a majority, but that was also before 4.00 a gallon gas and a majority of Americans telling the congress to go drill more oil.
