91 Octane

Slightly uphill at around 10pm. Temperature roughly 70F outside.

Sadly filled with chevron didnt get to test shells fuel :(

I had filled with chevron previous to the idea of switching to shells smh.

Same as previous log, only difference was swapping the #1 and #4 coil packs to see if the ignition advance issue follows the pack

Quality of fuel is atrocious feel like I should switch from chevron to shells fuel.
