STS Oil Change


Spurlee

Recommended Posts

I'm going to change the oil on my girlfriend's 2006 STS. Are there any unusual situations or tips I need to know? Is the cartidge filter on top or bottom?

I passed on the $14.00 AC/Delco filter as well as the $10.00 Fram and went with the (American Made) STP for $5.00.

2 cases of Mibil 1 ran me less than $70 a Costco.

Thanks!

Check for zirk fittings on your ball joints and tie rods, I think they have done away with them and they are sealed units now, but just check. Torque the oil drain plug to 15 ft lbs.

Heck, why not go with the Valucraft for $2.49?

You'd have to talk a long time to get me to believe there's a 300% difference between a $14.00 filter and a $5.00 one especially when they get changed every 3,000 to 5,000 miles. Spend your money where you want, I'll keep mine for things that make a difference.

I always use AC Delco, but I don't think I ever paid $14... Something is wrong with that price, shop around a bit. As a matter of fact an AC DELCO oil filter at Rockauto is:

ACDELCO Part # PF61 {#25014377}

FILTER,OIL $5.06

Since the FRAM is $5.00 maybe that shop is getting more vigorish selling the FRAM...

This calls for a cartridge one - CF2129 as I recall. WOW you're right - it's $4 to $6 at Rock Auto. Autozone had the AC/Delco, Fram and STP with the big price variation..they're ripping me off, or tried to anyway. Now I'm really glad I only paid $5.00.

I'm going to check around and price them...

Doesn't the '06 STS have a Northstar? Did they change the filter? I don't think I pay more than $4 for an A/C Delco filter.

I have the V-6 in mine...

No, the 3.6L uses an oil filter that is just the filter element. The 'can' is permanently part of the car. You open up the filter housing and change out just the element, which is cylindrical similar to this one in appearance:

Thanks for the picture - i was wondering where the filter would end up being. I hope the drain is easy to reach...

The paper elements make sense when you think about it - and should be cheaper (my recent experience notwithstanding) I help a friend with his VW Jetta and his paper-only filter is on the $9.00 range he says.

The "TopSide" location is great - much better than the "Engineer Convenient" underside location of most chevy 350's.

OH, I looked up a 4.6, didn't know you had the V6, that cartridge reminds me of the old days....

Yeah, wonder what the reason for that was.

Hmm I know. I would expect this oil filter to be expensive, as I would not imagine that many vehicles use it. It seems larger than a typical PF61, I wonder if its related to providing more filter area to offset by-passing better or maybe they didnt have enough room for an oil filter adapter?

The cartridge type filter design makes the oil filter very easy to change with almost NO mess/dripping. Because it is on top of the engine it is easy access.

Ease of recycling, minimization of waste, and reduction in trapped motor oil inside a disposed filter are often given as the reason for companies reverting to cartridge designs instead of spin-on filters, according to wikipedia.

Hmm, nice, thanks Bruce.

Here's my only experience with a cartridge type: On the Jetta it's located underneath like a regular filter behind a shroud held in place with many little non-stainless screws fitting into poorly affixed "clip threads". The shell housing is a cheap plastic with very small gauge threads and, of course, requires a special tool to fit the non-standard very large "nut" molded in. Us regular guys have to make do with a large plumbers plier which chews up the plastic nut and is too long for clearance. There is a hard-to-see rubber gasket which typically gets left behind up in the filter recess - you have to know it's there to fish it out with yet another long, thin hook-type tool. The oil will begin to leak out when there are still 5 turns left, so it's a slippery mess.

Now, the drawing up above shows a much better design, I hope that's what I have. Properly designed and located, a cartridge filter seems to have a lot of positives. And, there's no metal outer shell to create and recycle. Given all that, you'd thing that they will get cheaper as production and applications ramp up.

YEAH, same problems I had with my '62 Chevy 283. Funny how everything old is new again. Less Chinese steel and I bet they make GREAT fire starters when burned!

Never underestimate the amount of a persons greed.
