Since seeing AK's oil change DIY, I've decided to do my own changes and I'm leaning towards Redline. Considered Nissan's Ester, but Redline is a strong group V with excellent anecdotal evidence for smooth running and slightly lower temps. Once you get past a certain quality level, the decision is less about data and more about gut feel, which is strongly influenced by this board I admit.

Lol, I bought 3 cases of Mobil1 from Costco while it was onsale, and now I get to return it. Costco return policy ftw.

:twocents:

Although I haven't changed my oil yet, I decided to try Amsoil. Gotta tell ya, it was really nice just ordering it off of the Internet and having it show up at my door - doesn't get more "easily available" than that! :tup:

BTW, if you have any speedshops close by, many of them stock Redline.

I will be going with the new Castrol Edge, and DIY. I don't care if leprechauns jump out of the engine should I use it, or about any other facts or figures thereof.

FIrst Oil change
 

Around 1300 miles. The first one is on Nissan. Most likely change it again in 1700 miles; then swiching to syn oil (Redine or Amsoil). I likely will add Amsoil's by-pass filter to filter the oil to 2 microns and add some additional oil capacity.

If you do this can you please provide a writeup here so that we can see where you placed components? I've looked at doing the same, but the engine bay space is restrictive.

Sure; in the meantime, check out Amsoil's web site-bypass oil filter installations. A 2005 G35 sedan install one below the aluminum bumper. The bypass oil filter looks easy to install. I am not sure if the supplied Amsoil's oil adaptor plate that is installed at the stock oil filter location is a thermostatic sandwich plate or not. Amsoil's Bypass oil filters down to 2 microns.

I'll likely install a oil pressure gauge at the same time later this summer once my friends garage car lift is complete.

Pardon my ignorance but what's a by-pass filter and how is it beneficial?

I will be doing my first oil change at 1,000 miles (currently at 440 miles). This is a habit I have had since my first new car. I will be using Mobil 1 5W-30.

Then I will do my next change at 5,000 miles and repeat every 5,000 miles. Of course the filter will get changed with every oil change.
