I'm using 87 as recommended in the manual.
The AKI is an average of the RON and MON, so yes, you probably saw the formula listed on the pumped (MON+RON/2).HRWatson68 said:I need to check the pump more closely next time, because I am sure I've seen research octane numbers, and not AKI.
I'll report back after I see the pump.
