So many narratives on this issue and so little data, but maybe that's why we love this sort of conversation. Two thoughts, then I'll grab the popcorn.

1. What is really happening when you change gas? Are you getting cleaner burn, more power, change in engine temperature? Is there anything else happening that affects what we see? (Ethanol additives play a huge part in this as well, maybe more than octane.)

2. None of this is actual research. Get large sample sizes, blind study, run rigorous tests, and get back with us in 6 months. Get someone else to fuel up your truck every time, change randomly between fuel types (no diesel), and run 3 tanks before switching to the next fuel. Get that data over many samples and then bring it here to share so we can insult you.

TL;DR, drive slower, buy regular gas, spend the saved money on a decent 6 pack (no IPA).
