Regular or performance driving?
What grade is your car required?
For most people, going with whatever the factory recommend is good, eg. dino oil.
Some people prefer synthetic oil, which in my opinion last slightly longer and run better if driving style is a bit agressive. (your oil filter may not last as long as the oil, so watch out)
People who do racing/auto-crossing, they prefer Motul or Royal Purple. These are probably the most expensive type but their performance is guaranteed.
Motor oil is like gasoline, you need to experienment them. My car runs better and get more milege with 0w20 than the factory 5w20.
