Yeah, all the info here jibes well with what I know about oil. In my Eclipse, since it's turbocharged there's a lot of blow-by in the cylinders. The oil fouls extremely fast with carbon particles and gas. You can pull out the dipstick after 1500 miles, take a whiff and smell gasoline.

I change my oil on the Eclipse every 3000 miles. When I drain the Mobil 1, it comes out pitch black. If I do the same on my sister's Miata at 5000 miles, you can still see through the oil.

So, seeing as how this is both naturally aspirated and dry-sumped, I expect the oil to last longer. I've also seen many oil studied touting 20,000-mile oil changes but it makes me nervous. The dealership told me to use the electronic gauge and when it dips to the low mark, add a quart.

Oh and Randall, the dealer told me that due to natural expansion of the oil when the engine is hot, versus when it's cold, you'll get different readings on the oil gauge. He said I should just check the oil level when the car is cold and go by that.

Thanks for the warm welcome, guys.
