Quest

2004~2007 camry 4cyl engine all based on the same venerable 2AZFE(which is what my wifey's 04 has), so it's 87 octane rating.

Running higher than manual spec'ed doesn't make too  much difference in my case (tried as high as 94before) so I wouldn't pay too much here in Canada (price difference between 91 and 87 is minimal down in the sates).

I'm typically doing 500kms/wk these days (between Rmd and N.Van) and 87 makes good sense to me.

BTW: our calculation here in NA (North America) for octane rating (at the pump) is: RON(research octane number) + MON (motor octane number) divide by 2. Some countries only spec RON for their gas (sold through retail pumps) and there lies the differences.
