Does yours spec 5W20 GF3 on the cap like my Accent, Bad? Odd they would spec GF3. No mention of GF4. Mine isn't burning the factory fill, it's clean and clear as can be after only a thousand miles, I'm thinking it would be a waste to change it absent a situation such as yours. I got to where I was doing 5K on dino on the 2005 and 7500 on syn, and that car was clean as a whistle when I got rid of it. I figure they fill it at the factory with ultra-cheapo dino, but who knows? But it's hard to say it matters looking at the pics at the top of this thread, eh?
