Blend Calculator
Pump E85 isn't always 85% — its ethanol content varies by season and fuel class (roughly 51–83%), so set the pump's actual % above.
The pump's sticker says "E85" — that is a rounded label name, not a measurement of 85.0%. The % you enter below is your best number for that pump; the range fields under it (preset to the seasonal 51–83%) show the honest range of answers if the pump is actually at either end. Narrow the range when you have a tested number for your pump.
This app does blend math and station finding only. What blend to run is your and your tuner's call — it gives no tuning advice.

What did I get
Enter what the pump meter actually showed you pumped — the gallons on the receipt, not the split you planned. This mode recomputes from the amounts actually pumped.

Fix my blend
The blend in the tank isn't the one you wanted? Enter what's in there now and the % you want instead. The answer is a plan: add the correcting fuel if it fits, or drain or burn off a stated amount and refill — never just a refusal.
