Since this thread has popped back up.... Dwight, have you looked into the pennzoil ultra any further? It iis what I have used in my 370z since its first oil change. I also used it in my 2011 wrx for over 30k miles of hard driving . My wrx did not consume noteable oil either. Great cheap oil I feel.

I am doing an oil change next weekend and will send the sample of the Pennzoil Ultra in to Blackstone for a UOA. It will be the first sample with that oil, and it will have about 5000 miles on it. Will be interesting to compare with the Redline.
There has been some buzz on the Bob Is The Oil Guy website that there is some kind of new replacement coming for the Ultra. That may mean some good close out pricing on the current formula, provided you can find any. If you could find a 5 qt. jug for $25 or so I would buy a few.
I'll report my lab results when I get them.

Thanks for the heads up. my best friend manages an advanced auto parts here in town. So ill ask him what they got.

very curious on your results. Especially with 5000 miles. Im always a bit nervous to push it that far. I change around 3500-3750.

Anybody using the Purolator Synthetic oil filters, are they any good? I was using the K&N's but had a defective filter the other day, the car almost bled to death after two days. Thank God nothing catastrophic happened.

im using the black k&n filter right now.

I just started using the black K&N also.

I put on the purolator recommended here last weekend. No issues so far...

I used a regular purgolator filter, it was the same size as the stock one.

Did my first oil change today. Tons of help here. Thanks a ton for this writeup!

:tup:

just did the first oil change since buying my z. i'm no noob, i've been working on my own vehicles for over a decade, but there's something special about doing the first oil change. makes me all tingly inside.

I know what you mean. I drank a glass of the first oil I drained on mine.

Gotta Luv them Magnetic Oil Drain Plugs!
 

re: Magnetic Drain Plug

OK, well you guys got me all worried about nuthin' I suppose (most of the metal particles aren't ferrous anyway) but I went ahead and installed a magnetic drain plug.

I found mine on Amazon: Mishimoto MMODP-12125B Black M12 x 1.25 Magnetic Oil Drain Plug ) 12 x 1.25mm (fine thread).

The first time I ordered I just specified 370Z and they sent me a 12 x 1.50 (coarse thread, I think the pkg. was just mis-marked) so I had to send it back. The second time I specified 12 x 1.25 mm and they got me the right one. It seems well made and has one helluva strong Neodymium magnet in it. I can't wait to capture all them steel chunks!

Also: I returned this one due to a very weak magnet: NRG M12 X 1.25 Gold Magnetic Oil Drain Plug Part # NOP-200GD (from Auto Dynasty).

yah, sounds like a typical mishimoto product.

The only Greddy part I have is a magnetic drain plug.
