1993-1997 Toyota Corolla best oil?
 

I really need to change the oil in mine.

I like this car. It's punchy. It has a 1.6L .. much like a Civic EX just that Toyotas don't have a problem with disappearing from in front of your house or apartment.

I was going to ask somewhere else, but, I mean, I can think of at least one fairly useless forum.. that deals with cars.. I have a dedicated stalker and I wish very bad things to happen to him unless he changes his life and lives FOR HIM and NOT ME. (I assume it's a male, I probably have some I don't even know about. They don't even know their efforts aren't working.. THEY SHOULD JUST STOP...)

What's the best oil, and sure, why not, filter?
And any harm in a cheap Purolator Classic white one?
