Thumbs down Best fuel!?/////Whered all the 92octane go?!

California valley user here, i cant find 92octane anymore! What the heck!?

What about other states!? What ratings can you get? Ethanol %?

anyone eaisly get 85octane?

And finally what do u run and why?

Im running a compresion ration of aprox 9:5:1

She pings with 87, 89 is just 87 and 91 blended so i stay away from that, 91 runs great in winter, ritch in summer.


Check this out, do a test. Buy 20 bucks woth of 87 then 91/92. Do u get more with the higher rated?
I have a newer sending unit and guage on a single 12g tank so needle accuracy is pretty good, and with 92 the needle is higher despite the price increase.

I also get better mpg with higher octane despite timing or comp ratio.

Tested in my 2003 hundai sonata v6 with cold air intake, averaged 2 mpg better with cold air, 2 mph better with octane...

Ding ding! FIGHT!
