Ok so I'm trying to hit E50, I'm confused on what to do, I guess I'm suppose to go with the total in my tank 20.5l and the e85 I have is measuring at 85. And tank has 91 currently in it. Need some help mixing. TIA

Supra gas tank is 51.86 liters

You're at 20.5 liters

Your in-tank level is ~40%, not 20%.

At your current gas level, to reach E50:

Add 3 liters of 91 octane.

Add 28L of e85 from that pump you measured.

Your total tank will be exactly E50, with a final octane of ~98 AKI.

To prevent overfilling and ensure you reach E50, under-fill the gas number a bit and make up the rest with the e85.

I really appreciate your input thank you.
