C cdesigns Member : Mazda CX-7 Aug 26, 2007 #1 Guys is weird but, I have been running 91 octane instead of the 93 octane gas and the engine feels more powerful than with the 93octane. I haven't check gas mpg but it feels better, no knocking. and is cheaper (yippy)

A AWmustang Member : 2009 Mazda 3 GT Aug 27, 2007 #3 91 is the lowest octane required by the manual.... unfortunately no gas station by me sells 91. My choices are 87, 89, 93.

R Rick's CX-7 Member : 2014 Mazda6 Aug 28, 2007 #4 I've been running 89 for over 2000 miles now without any adverse effects. I've taken a good beating for it, but it's all good! http://www.mazdas247.com/forum/showthread.php?t=123674218
