I just picked up 14 bottles of the Castro GC 0w30 for $6.89/L. I did my first oil change at 15,000kms and the oil seems like it was still good. Not sure if the color makes a difference but I'm assuming the more black it is the sooner you should have it changed. I think I'm going to try and do 17,000-20,000km next and see how it is. I still have enough for 3 more oil changes after I stocked up a few days ago.
For all you Canadians I got it from Canadian Tire. They are on sale for $6.89/L until Thursday I believe.
