What number gas do you fill in a 2005 Corolla. My mechanic said 89 and our relative's manual says 91. Whats the right thing?
Corollas should only use 90.3 .... :roll:
Our manual syas 87 no higher
The dude lives in denver his says 91
EPA Gov (http://www.fueleconomy.gov/feg/noframes/20797.shtml)
According to this, it's regular...so 89, right?
.... does it really matter?
