what do i need to do? Do i need to flush out the engine? If so what do i need to do this?

 

i was wondering the same thing, but for the changing brands of blinker fluid...

You shouldn't have to flush the engine if you're just changing brands. But if you're going from dinosaur oil to synthetic, it wouldn't be a bad idea. About every third or fourth oil change, I flush my engine (this is on my other car since I haven't even changed yet on the CL-S). I just get a quart size can of stuff that's creatively named Motor Flush (if I remember correctly). It's a silver can with a red label but any brand should work. Just pour that stuff in the cold engine, idle for five minutes and then drain.
