There's a lot I would use and would consider high quality: Valvoline VR1, Driven, PennGrade, etc.
X2 and VR1 usually easiest to get, unless you need an odd weight, Walmart carries and often has it on sale.
I used to use Penngrade and loved it, but my supplier stopped carrying it locally and hate to pay shipping for oil.
