3. Octane is roughly a weighted average:

A 50%/50% blend of 87 AKI and 93 AKI would get you 90 AKI.

A 50%/50% blend of 89 AKI and 93 AKI would get you 91 AKI.

A 33%/67% blend of 87 AKI and 93 AKI would get you 91 AKI, and generally be a little cheaper than the 50%/50% blend of 89 AKI and 93 AKI.

Gas pumps make 89 AKI from a 67%/33% blend of 87 AKI and 93 AKI, or a 50%/50% blend of 87 AKI and 91 AKI. But, they generally charge disproportionally more for 89 AKI

Very good info. I am going to use this to fill my x5
