I drive an 08 OR. I (very) rarely tow. Mostly highway miles to date, but some city (and a lot of off-pavement) in the mix.
I run 87 (reg) almost exclusively. I run Premium once in a while, meaning about once every three months, to baby it a little. I add injector cleaner every 12k or so,... (25k and counting on my pf).
No issues to date: no pinging, no nothing. if you're towing or adding strain, consider the good/expensive stuff, otherwise only once in a while and she'll love you just the same.
One note: most miles to date on my PF are in west TX and northern Mexico. I'm not sure of ethanol/other mixtures in those regions which may affect things.
