Pumped 2-3 gallons of regular before a realized what was up.

Completely empty, filled the rest with 93...any suggestions?

 

I wouldn't be worried about it

 

Burn it to the ground. Its totaled.

 

Just go easy try not to boost until you refill the next tank if you have wideband just watch the gauge making sure it doesn't go lean under boost.

 

You'll have a slightly reduced octane, just try to resist aggressive acceleration for this tank.

 

Is regular rated 87 octane at the pump?

 

I highly doubt there's going to be any measurable decrease in performance or danger from a couple gallons of regular topped off with 93. Figure a lot of states make do with 91, and I imagine the blend in your tank now probably has a higher octane than a full tank of 91...

 

Lmfao

 

Yeah, I did the math for 3 gallons of 87 topped off with 11 gallons of 93. You're right the octane difference really isn't worth worrying about. It averaged out to approximately 91.7. Almost 92 which is what they have up in the State of Washington for premium.

 

SWeet. I romped on it anyway last night a bit, and had no real issues. good thing I caught it.
