I use 10W-30 AMSoil or Mobil1 fully synthetic. But I live in tropical climates and have never had the cars in anything colder than 55 or warmer than 98.

Sorry, had to edit my typo of 0W-30 to 10W-30

i up to know i think have been useing 10-30 valvoline synthetic.

I started using valvoline full sysnthetic 5w30 about 1000miles ago. I get it for free so I can't complain. The only thing is it's winter here in CT and on initial start I have a slight tap due to oil just starting to be pumped up to the head.
