 SHOPPING
ended up just going to A1 Auto Parts at Goodna.  3818 1812  The reason being that their oil seemed to be slightly lower cost than the three big chains.  When we were there it was way easier.  Go to the counter and ask.  I find at Superchap etc that I spend ages scanning the shelves looking for the part.

PETROL v DIESEL

Both Nissan and Captiva say 5W30 BUT Is there a difference between engine oil for petrol and diesel?

 HOLDEN CAPTIVA 7 CX, LX, LT, LTZ Auto CG CD26 01/2011~01/2019 4 Door SUV 4WD DIESEL 2.2 litre, Z22D1 (LNQ) I4 16v DOHC VVT Turbo Direct Inj {135kW} 

The Captiva Service Manual says the oil should be 5W30 (Dexos 2)

The Nulon web site says use Use 5W30 Diesel Dexos 2

The Diesel stuff has a 2 in the bottom right of the logo.

The diesel stuff has a yellow "30"

This has a 1 at the bottom right of the Dexos logo but has the word "Gen 2" at the bottom right of the label underthe word Dexos

From the Nulon Web site.

Highlights the "Diesel" version

 

 PHONE CALL WITH NULON
I was wondering what the difference between Dexus 1 Gen 2 and Dexus 2 was so I placed a question on the Nulon web site.  They called me.  It appears GM have decided to require very high spec oils and oil makes have to pay a lot to get the oil accredited so they can put the Dexus tag on their packaging. Apparently some needed to sort out a sub audible knocking on US 8 gear cars.  The Diesel oil can be used in petrol engines but not vis versa.

Costco did a deal with Nulon.  The Costco "Protect" range are basically the Dexus oils but of course GM would not honour any warranty stuff.

Today did the oil change

 

This is the engine.  It's at the front of the vehicle.  To access the oil filter which is at the top left, I had to remove the oil filler cap per the video above and also undo and move the air tube.

I wiped out the inside of the oil filter with a paper towel.  The oil while black did not feel sandy.

The oil filter came with a new O ring.

I lubed it with some of the new oil.

I make ramps using some bricks.  The back wheels are chocked forward and aft.  Not keen on Jacks in case the car slips off.

Presented with a dilemma.  Which is the sump.  The video confirmed the black one.   assume the aluminum one is the gear box.

The left over oil was poured back into the original container.  This is  5L container and I put all 5L in but there was slightly more than 5L taken out.  The dip stick though has the new oil at the mid point.
