remeber the dyno i showed you? that was with 93 octane, and the car made around 270. on 89 octane the car makes around 240. To me an extra $3-$5 at the pump seems worth it.

Its also not that much more expensive. Currently uleaded is 1.89. I usually get about 12 gallons. Which is $22.68.
Now for premium its 1.99 and for 12 gallons thats $23.88 per fill up.

Yea breaking the bank with that buck 20.
