I usually use 76 or Chevron - they're closest to me and have pretty decent prices for Burbank, CA. I find I have to use the 89 octane mid-grade or I get pinging in the 3slow.

87 is $2.31 here, and thats for arco brand

It's $2.23 here in Boulder, the Shell station is 1/2 block from my house so I always tend to fill up there. I don't notice much of a difference between that and the mid grade. I'm getting right around 16 mpg in mine and I hate it.

can i ask a semi-related question?

i always fill with 89. will it make a difference if here and there i put 93 or 87? like very 10th tank or something?

nothing, I also experienced ˟˟˟˟ty gas mileage with the shell v-power i got arround 170mi to a tank of gas w/ a 22re, and I didnt run it hard or anything like that just normal driving. Oh well time to start fueling up at the BP

I've found that I have to use 89. If I do a tank of 93 and then 87, the 87 tank will ping. It's not that the higher octane gas can offset a lower octane tank. The octane rating is needed for each combustion cycle.
