Mix 3:1
I really enjoy my car and drive it hard such that the oil is 260F+ on a regular basis (it doesn't take much... just sitting in traffic and a few consecutive wide open throttle pulls on off ramps and merging can do this). And I live in CA where 91 octane is more like 89 octane elsewhere (check out the Cobb and other forums for more info on this).
This mix brings my oil quality to "93 octane" and if you believe what is posted on Cobb and other sites, it is really just bringing the fuel quality up to the level of 91 octane elsewhere in the US
I figured it makes sense to get a bit more protection from detonation given how I use the car. I am not expecting power gain or any other benefits other than more safety margin from detonation. If I had access to 93 octane I wouldn't bother with this. |
Thanks for the info. Here in NC, I can pump 93 at shell and bp. Lucky.
