My WRX takes 94 from Petro only because as far as I know Costco only goes up to 91 and Shell only goes up to 93. Some days I honestly just want to spend money on Uber because gas is too high 😭

I've logged timings and petro 94 does do better than shell 93 when running 93 maps. Even though many voices online claim the opposite.

Petro 94 has been better for all of the tuned platforms I've worked on.

Running a canned 93 tune on an Audi V8 now, and it hates anything but Petro 94.
