Re: octane in my svx
I have proven that my gas mileage will suffer under highway cruising with lower octane. I got 30.9 with 93 octane with 10% ethanol blend from here to about Indianapolis where they had 92 octane, got about 29.5 so slight changes in driving conditions could apply there, but every time that I have put 91 octane in , either with or w/o ethanol mix, the mileage drops to about 24-26 hwy mpg's...
These were all on my laguna fwd SVX. Considering 93 octane is generally found here for 16-20 cents more than regular, I'll stick to 93 octane.
