87 unless I'm towing, then I run 92.

 

Livewire tuned 93 octane. Just put a 4.56 gear in so we will see what the mpg is.

 

93 for me

 

87...cant hardly afford it

 

ya i cant really afford mine, its so hard to try and drive slow and stay out of boost, I really just cant do it for one full tank. But if you think about it, 87 here is 3.09, with a 25 gallon tank, thats $77. 93 octane at 3.29 for 25 gallons is $82. so there is only a $5 difference between the 2. not worth a tune change.
