The best weight oil is whatever the hell it on sale.

The oil cap says 10w30 which is perfectly fine for summer driving but 5W30 is better for winter starting. I always ran the cheapest crap I could buy at napa and it took it like a champ for nearly 5 years. $20 oil changes FTW.

Of course oil brand is up to you, to me it's all the same unless you want specific oils for euro cars or high performance oils with extra zinc/metals in them.
