that 100 Octan fuel costs about $4.30 a galon at last time I used. I use that 100 octan as 50% with 91, my non-SC ran so smooth. Now 91 octan at that 76 staion costs almost $2.30 and the 100 octan is still around $4.5 a galon. I think $4.5/gal is not too bad for an SC going to off road sometimes.
The 76 is at Almaden Expressway and FoxWorthy in San Jose, CA near Capitol ExpressWay. Let check that one out , your SC will love that blue fuel.
