So Ethanol Free >> Ethanol for the MPG numbers, but which octane should I be buying? Some gas stations near me have 90 others have 87.
On my fuel log I track the gas type used. That's the 2020 log, you can find my older log (Pre-Lithium) in there as well. |
since it has VVT buy the highest octane you can afford you will be able to pull a higher timing on it
with 87 i barely get 18.5/18.5
91 octane 23/31.2mpg it's able to pull a tight timing of upto 42 degrees advancement with it
it's normally around 27-35 degrees on average
with 87 oct 12.5 degrees advancement is where it tops out at retards the timing in AFM mode to about -2 to -12 degrees it would also rapid flip flop between v8 and v4 (sure that can;t be good for the engine)
it's more likely to search for gears with 87 octane
