What motor oil are you running?

Thanks and yea im trying to get every mile out of this engine i can. how often do you change your oil? i do about every 2500 to 2700 depending on how it looks, i do mostly city driving so its a little rougher on the engine than highway or country miles.

Honestly I usually trust the Oil Change Required system because if I'm not mistaken it will come on earlier or later depending on how your driving? it ends up being about every 3,000
