Conventional car engines won't produce temps or pressures high enough to break down the lubricative properties of conventional oil. There have been numerous studies done on this.

That being said, I still put synthetic in my BMW!

A little history on synthetic oil:

He listened to the noise and he says 95 percent chance is the lifters. i told him will this sieze the engine, he goes i dont think so. I asked him also, how much to repair and he says 1000 to 2000 depends what is needed. So since my car is only worth like 3000$ i am just going to use it as it is and do all other maintence and live with this small noise. Or, if one of ya'll can give me a link on how to do this lifters change ( is it expensive to buy the parts, is it tedious job to do).
$1-2k for what? I'd get a new mechanic.

Did you check your spark plugs even? Sounds like one is loose or an exhaust leak.
