I usually fill up at Shell or Valero. I'm tuned for 87, because back when I first got my tune 93 was well over $4 a gallon. Fuuuuuck that. 75-85 to fill up is hard enough on me. $130-$150 a fill up is outrageous. Back in 08 87octane was over $4 a gallon and was easily spending $125 to fill up at least once a week. It got so bad that I bought a shitbox Honda civic which I filled up for about $40-$45 about once a week if that often. But I sold it within a year, because all the money I was saving on gas, I was spending on repairs for that 200+k mile POS Civic. But I got it for $1000, spent about $1000-1200 in repairs in the year I had it, and sold it for $1900. So I made almost all of my money back on it at least.
