3k-5k depending on your driving habits. Being the cheapest synth
blend oil here I wouldn't expect wonders. I've been using this
oil for quite a while with 3-5k intervals and I'm happy with it. It's nice
and clean when it comes out and there's still
no oil consumption at 165k (I have a Zetec). I do change it
regularly though - I plan on keeping the car as long as possible
and $10.92 / 5qt will not bankrupt me.
