I stand by Castrol Synthetic blend, and or Full synthetic I run my engines hard. I just had it fully rebuilt ran Synthitic in it from the start, and have before almost ran the engine out of oil, and it never blew up, I don't care what anyone says Castrol synthtic works. And my uncle has put it in engines that smoke and it cuts engine smoking in half.

Thiner oil will give you more hp, but not if its cheap oil, because it'll wear your motor from accessive heat, and viscocity break down, but as long as its synthetic, or Castrol oil use 10-30 LOL Or Mobil if your rich! LOL
