So yeah, basically I was half asleep and before I realized it I was 4.5 gallons filled with 87 octane. Whoops...

I filled up another 6.5 gallons with 93. Will I see any effects? Obviously I know my engine isn’t going to blow up but I’m just wondering if I’ll see any repercussions.

I don’t think you have anything to worry about. When I first bought my SI the dealer initially filled it with 87. When it was at about a quarter tank I filled it with 93 and didn’t notice any repercussions from the mix.

If you’re stock you’re perfectly fine, if you’re tuned, don’t drive it like you stole it until the 87 is out. Try octane booster too

Exactly. Lock the thread now before people come with their false info.

It's fine. If you calculate you essentially have 89 with the mix of 87 and 93.
Anyways its regular required premium recommended so the ecu will adjust and you will lose a bit of power but that's about it.
