If you mix half 93 oct and half 89 oct, do you get a 91 oct in ur car??
Just saw that 5 page thread about what grade gas to put in ur 2nd IS, and it made me think of a question.................. maybe someone with some expertise in this area can shed some light on this issue?
I'm wondering if you get the same 91 octane gas as in the gas stations if you just mixed half 93 and half 89. the math works out to be 91, but is it really a 91 octane gasoline??

Where do you get 93 octane gas on a regular basis? Most gas stations serve 87, 89, and 91.

The answer is yes, you will be 91 when mixing two together. Remember not to get anything higher the required octane rating stated by the manual since it does not get you anything better. You may FEEL better and want to think it is better because you pay more, but it is really not.

). Added octane booster, burned a portion of the fuel, and then filled up with 93.
