Yo, you can use 0wt-30 if you want........the thicker your oil, the more HP you will be losing and/or power. AMS 0wt-30 is what I use........5wt-30 is good too. AMS oil will save your engine too......it's truely synthetic and is way better than Mobile 1.
BTW-The HP diff is minute between oils, but the overall protection and reliability is there with AMS oils.
