Just wanted to bump, and to say thanks.

This was too easy. Those not changing their own oil should seriously consider it, with the 3.6 it's a piece of cake.
 
Thanks so much for posting this article and the great photos! I had the first oil change on my 3.6L 2006 STS4 done at the dealer at around 3k miles, but I somehow got the feeling that all they did is reset the meter and didn't really change the oil. Car now has 6k miles and I'm going to do it myself.

I put the car up on ramps (low profile ramps available at Wal-Mart, my "normal" sized ones don't fit under the low STS front bumper) and spent about 15 minutes looking for the oil filter! Couldn't find it and although I guessed that it might be in the canister up on top of the engine, I had never seen one like this before.

So I did a search in the forums and found this article. Great! I will try it this weekend. I bought a WIX filter, couldn't believe how small and light it is without the metal canister that "normal" oil filters are supplied with. The shop owner couldn't believe it either...

Anyway, I'll report back if I discover any tips. Thanks again!
 
I've done 2 changes on my '06 one at 2250 miles and the other at 8250. I ordered the AC Delco PF2129 filters from Advanced Auto for $4.99 plus shipping. Came out to less than $20 for 2 filters. Sam's Club has 6 packs of Mobil 1 for $27, so basically $37 for a 6 qt Mobil 1 change with filter.

I love the filter setup on this engine.

Hi, I have several AC oil filters, none of them come with o ring seals that fit on the top of the filter housing. Do other brands supply the o ring with thier product? Tom
 
I think the real beauty about the new oil filter element design, is that there is virtually no oil left in the element to despose of, unlike a spin on design where there is always 1/2 litre/quart of oil left.

Seems that all newer engine designs are going to this design. Chevy Ecotec, Mini to name a few others.

I'm not a tree hugger, but I do think we need to take care of this earth a bit better than in the past.

The oil change on the CTS 3.6 is the most easy one I have ever done, of any vehicle I owned, I drive her up onto my Low Profile Rhino-Ramps, change the oil filter, drain out old oil, refill w/6 Qts, Mobil 1 5w30, & reset DIC......for about $40.00, you can't beat it......I can do the job in about 10-15 Mins, then I bring old oil to Pep Boys & they take it no problem......
 
I know this might sound stupid but which way to you turn the canister to take it off? I know there is an arrow on top of the cap that points the wrong way and i dont want to crany it one way and be wrong and tear the aluminum off it!

Is it clockwise or counter-clockwise to LOOSEN?

Righty - tighty, lefty loosey. Turn it counterclockwise to loosen (same as the drain plug). The arrow is in the direction to tighten (also withthe torque 25 N-m). You can use either a 24 mm socket or 15/16".

The 2008 uses the same filter / drain plug as the previous 3.6L, but there is a shroud under the engine that needs to be removed (4 screws and a few push clips) and the upper engine cover needs to be lifted to take the filter out. Probably adds 30 minutes to an otherwise simple oil change.

I'll post a new thread for this in a month or so when I change the oil on my new car.
 
stupid question coming.... after the DIY oil change, does the computer automatically detects the new oil and change the specs to reflect the next oil change? thanks
 
i'll try to change it myself in 2 weeks! Last week, I went to the dealer just for little question: what type of oil did you put in my car? 10w30. Synthetic or regular? Regular why? Nahhh nothing, just by curiosity, tks!! So I'll wait til I have 5000km made with the actual oil before changing it but after that, I'll put back synthetic!

But you're talking around 30-35$ for 6 qts of oil!!!!! Here its 40$ just for a 4.4L so I'll need approx. for 60$ of oil.... where in canada, can I find a place where I dont have to give my wallet for an oil change?! Tks!
 
I pay about $50 bucks for my oil change....looks dam easy...I am gonna start doing my own......Unless its cold outside...
 
just did mine by myself last friday.. took 23 minutes to be exact! Very easy in fact! Cost here in Canada to do it myself (oil +filter) 74.50$ ax incl. Dealer wanted 135$ + tax + letting my car all day at the dealer...

Tks to all of you guys! :D
 
On my previous car I installed Fumoto Valve - follow this link and you will see what it is: http://www.quickoildrainvalve.com/ProductDetails.asp?ProductCode=F107NA

I have CTS 08 with DI engine. It seems that to get to the oil plug I will need to remove a plastic cover underneath the car. If I could install the Fumoto valve I could connect a short tube and drain the oil without any mess. It works on my Infiniti....anybody out there tried this valve?

Nope. You have to manually reset it.
 
listen to the chick, you gotta hold the reset or clear (CLR) button

when you see canadian tire have a sale on mobil 1 buy it, i got 2 - 4.4L + a 1L for 90 with tax this week. thats 2 oil changes. im gonna keep lookin for sales and buy enough for 2 changes at a time.
my 3.2 takes 4.8L so this works out perfect for me, im not sure what the 3.6 takes.

btw the oil change on the 3.2 isnt that messy at all, i think its a caravan that the oil filter is next to the exhaust and towards the front is the worst, i useto work at mr lube and i burned my arm on those soooo manny times.vw's are stupid too, i think it was the mid 90's disel that was under the headers/exhaust manifold.
i had my drain plug changed from the torques to a regualr wrench drain plug, didnt use the oil filter drain, i just took it off and let it fall in the drain pan,
the cts is 2 low to put on my ramps without removing the bumper so insted i put 2 wheels on the curb and just went at it, perfect height just make sure you have it so the high side of the car is the opposit of the drain plug on your oil pan.
to be honest the only tool i used on the oil change was a mastercraft adjustable wrench, used it on the drain plug and filter cover, no issues.


does the 3.6 take the same filter as the cavi/colbolt ecotech? looks like it.
 
I know wal-mart regular sales for a 5L of mobil 1 is 38$ + tax. They only sale 5Liters no 4.4L. I go at the dealer for my oil filter: Ac Delco PF2129F.

the car holds 5.7L of oil and for the drain plug, I do the same thing as you, I turn left the wheels so I can slip my arm throug there and take off the drain plug. No need to lift the car. For the oil filter, its on top of the engine, to his right side when stand in front of the vehicule. You can find some picture around here to see how 3.6L guys we change our oil filter.. very very easy, no mess, no drip, no burn at all!
