What kind of oil do you use?

Oil is like religion in forum, so I won't get into a war of words...LOL.

This is what I use:
- Summer 10W30 synthetic, change every 5K or so.
- Winter 5W30 synthetic, change every 5K or so.

I usually buy synthetic from NAPA auto (made by Valvoline from what I was told). When on sales, it is about $3.60/qt.
Or you can get synthetic Walmart brand for similar pricing.

I personally don't want to spend more than $3.50 ---> $4/qt. To me anything more than $4/qt is a waste of money.
