I haven't even picked up my first 993 yet and I don't want to feed her with the wrong juice when I do.
What fuel types are you using? Octane? Ethanol or non-ethanol? What does Porsche recommend?

Use only premium unleaded gas. What octane that is depends upon the state you live in, but anything over 91 should be fine. You are unlikely to get a choice of with or without oxygenators (ethanol or otherwise).

Thanks, the only reason I asked about blended fuel is because I had run into an issue with ethanol in my ducati. Apparently it deteriorates the plastics in the fuel tank causing a gross distortion in it's shape over time, a very short time. This issue is only in the US since the EU doesn't blend their fuel.

Me likey Chevron with Techron. 91 is the highest we can get here in California. Using (R+M)/2

Major brand 93 Octane without ethanol (which, BTW, costs more to make than the gasoline it's supposed to save!). BTW, I pass up any station where I see the tanker delivering. They stir up the sediment.

Around here I can get 93 octane and Philips 66 has non ethanol. I use that or Shell or Chevron.

Just filled up with Citgo 93 Ethanol free the other day. Sounds like the way to go but I'm no expert.

Chevron 94 here in BC (Canada, eh).

Same here but I am not sure about ethanol content and if it is used to boost the octane ratings. Anyone else know? All I know is that it is the highest octane rating I can purchase locally.

91 is the best that I can get here in Nebraska and seems to work fine. Used to be able to get 92 at BP but they went down to 91. I always say no to corn gas. I have respect for famers but not going to support their lobby.

Someone was just telling me that it will deteriorate rubber seals as well.

JP-5. The car smokes a bit but I think it helps lubricate the fuel injector pintles better than regular fuel.

JP-8: If its good enough for an SR-71 @ Mach 3.2+, then it oughta be OK for a 993, yes?

PS,....boron cartridge needed for initial start, tho.

super+ 98 or ultimate 100
