Octane requirements

Nothing to do with the question asked, but my 2011 1500 Sport 5.7 does not like lower octane gas. I've used 93 octane since new and it has never had an issue with knock. After gas went sky high I tried running 87 octane (lot of posters on Ram forum said it won't bother it), that thing ran like doggie poop. Missing, and knock. Back to 93 octane for me, you just have to go with what the engine likes best.
