For $300 dollars they should be doing the oil change for your car AND giving you a short shifter thrown in for free. There are a lot of threads that may help you decide what kind of oil and filter you want to use.

I know a lot of Nissan/Infiniti dealers use ENEOS for their 350Z/G oil changes. I am sure if you buy the filter, and get some ENEOS or similar oil, you should be good.

My oil change was short of $50 at the Nissan dealership... and they use Mobil 1 synthetic. They also topped off my fluids.

$300 for an oil change? I know what the lube is for.

Umm im sure your eclipse does just fine w/ amsol but i would change it a lot more often than 25k lol... unless you mean 2.5k... seriously better safe than sorry

I'm pretty sure you're talking about the $250 overall maintenance and inspection they can perform at like 10,000 miles.
