Mobil1 0W-30. It flows the easiest at start up and protects like all the other 30 weight oils when hot. Since it is synthetic, it is no more prone to break down than the others either and still protects at hotter tempetures than regular 10W-30 oil, so it is not too thin.Jliao said:What's the best oil for the P5? and what do you guys recommend? I know Synthetic oil is better, but which brand..etc..
Thanks
