What brand of gas do you use?

I use Chevron 91, I've never seen 94 at any of the Chevrons where I live (San Jose). Where do they have 94?

I always fill-up at 76. The 91 octane (best we can get in the west) is $4.09 right now. I've been getting 28-29 mpg on the freeway in my 2.7.

It's $4.13 a gallon now...ugh.

$55/tank.

I always use 91 Chevron. I've tried 91 76 when I was super low one gas a couple of times. I noticed no difference.

I don't get it,why are some folks running cheap gas in their sports car? You want something that runs good on cheap gas? Go get a Civic or scooter. DON'T BE CHEAP ON YOUR FUEL if you want your car to last you many many years.

I went out to VIR last weekend to see the races and filled up with 100 octane lead-free race fuel they have at the track. Quite an experience just filling up. At 7.50 a gallon, I maxed my credit card charge for the fuel at 75.00 for the first 10 gallons, and there were still 5 more to go!

The car seems to sound different with the 100 octane, both at startup and when driving. For example, I think it's gurgleing more than normal when slowing down. Its hard to tell with my butt dyno if it is making much of a difference. Seems to run faster at higher rpms, but if it is, it is not a day and night difference. Interesting experiment, but I think its expensive to try again,
