Is there a reason why you can't get anything higher than 92 here in Seattle?? Is it a King county law or something? I know you can get 100 octane at Pacific Raceways... and I've heard rumors of one 94 gas station in Auburn.. but that's it?

I can't imagine why there wouldn't be a few places... I'm sure they'd do fairly well with the amount of tuned cars around here.

 

I'm not sure on the answer. But is there a significant difference between 92 & 94 performance wise.. I wouldn't think so. But you tell me, I'm curious.

 

Well looking at the current tune from APR for my S4, I either have to run a 91 octane tune or a 93... and it's a fair amount of HP... for the same price.

Not a huge deal, just got me thinking. Trying to figure out why everyone here tops out at 92.

Seems like everywhere else in my travels has 94.

 

I think a lot of tuned cars prefer to run E85. Even though it is still hard to come by in the Seattle area but that seems to be the trend. I'm mostly familiar with other Evo owners but I'd assume that it would also be true with other turbo/tuned setups.

 

Ive also seen posted that high octane is available here:

Thrasher's Corner Shell
Address: 20702 Bothell Everett Hwy, Bothell, WA 98012
Phone: (425) 398-3774

101 unleaded

110 leaded

 

Just called and confirmed with Thrashers corner Shell, they do sell it and it runs about $8.50/gallon.

 

Well, now we're talking race gas.. and another tune! lol. Anyone know why 94 just doesn't exist here?

 

You can mix the racing gas with premium to achieve your desired octane.. but is it really worth the hassle? Unless you can flip a switch to change between tunes I wouldn't think it is worth it.

 

Yeah, it's not worth it. For now, you have to pick one tune but in a few months you'll be able to switch between the 91, 93 and the 100 using your cruise control stalk. It's kinda cool. Just more bummed that I'll have to run the low 91 tune and lose 15-20hp. lol

I also imagine this will affect the 997 when I do the exhaust/tune this winter... perhaps not as much.

 

I don't think you could ever get 94 octane gas here ever. They do have them up in Vancouver BC though. It'd be a good excuse to make a drive up there.

 

Almost every chevron in Great Vancouver Area has 94 gas, but you might have to pay $5 per gallon for it...

 

Cenex carries 94.

Is there Cenex anywhere near Seattle? I've never heard of that.
