Hi last time i made a post it was about my lift not working cleaned the screen and the engines great now, this time id like to know what fuel i should put in it, i run 87, i'm in Michigan so i can choose from 89 and 93 as well, so what octane should i run? thank you for the help!

The GT was designed to use premium fuel only, it should be 91 octane or higher.

It's outlined on page 6-4 of the 2003 Vibe owner's manual.

Have folks tried alternating tanks of 89 & 93?

I'm one that alternate tanks every other or every third fill up. Costco, last week, had their 93 premium for $2.02/gal so I gladly went that route. Lately (past several months that is) fuel prices here at the Ohio/Michigan border have been so low that I don't mind the extra 40-50 cents for premium which my 04 Vibe Gt needs anyways.

I like hitting lift too much to run anything lower than 91 octane. Sadly, it is extremely expensive in my area..We are at $2.59 for 87, and I think around $3.29 for 91+.
