Finished oil change on DB9
First time in my life so took a loooong time to complete, damn difficult. But 2nd time will be easy.
Took 12 quart of oil mobile 1 0-w40 ero formula
Only problem I am left with is I can't put the clip back on air intake hose
Not the big one which goes in to throttle body but one smaller one on lower side of throttle body.
Any special tricks? It is so hard to reach, may be there is a special tool?
I am doing to go look for extra long thine nose plier may be that will work.
Also one trick I did was
Once the filter is loose, don't try to bring it up filled with oil which can spill everywhere instead let it sit up right in the area near oil pump
Get a fluid pump with long tubings on both side, empty the filter
Now it gets light weight and can be tilted to bring it out from the top, without spilling a single drop.
I just did my DB9 Oil change over the weekend. I replace the aston clip on the air intake hose with a standard 5/8" hose clamp. The trick I used to remove the oil filter was after loosening it I placed a plastic bag over the loose filter before completely removing it.
Just because a filter is a similar size and screws onto the threads doesn't mean it is correct for a car, especially a high performance one.
There are a few parameters to consider such as oil flow, micron particle size, bypass pressure etc.
Do you buy cheap oil as well? What about second hand part worn tyres while you are "savng" money.
If you are doing the job yourself you are already saving loads. Fancy an engine rebuild caused by saving pennies?
I am trying to change my oil on my db9 but there is a wireclip hooking into some aluminum line that is behind the oil filter so i cannot unscrew the filter the entire way off. I tried disconnecting the clip but i cant get it off or out of the way.
So you're saying you can't even unscrew the filter all the way before it hits that clip? I just did my oil change weekend before last on my DB9 but didn't have that issue. When the filter was unscrewed all the way there was still clearance to that clip - not much but there was clearance. I didn't have to remove any clips by the filter. Can you rotate that clip to buy you just a bit more room? It seems like you should be right on the verge of having the filter come off - like you're on the last half thread or something.

I was able to unhook the clip but there still wasnt enough clearence. No matter how hard i tried the metal line would not move so i couldnt get the filter off. I screwed the filter back on and filled the car with oil. When i have time ill take it somewhere or pull the undertray and see if i can lossen a braket for that line and get it out of the way.

Just curious - what year is your DB9 and what is that metal hose/connecter for or connected to? I have an 08 and I don't have that metal line there - hence why I had no interference issues removing my filter. It's hard to get a picture of the filter location once all the air ducting is back in place.

Its a 2005. I couldnt tell what the line went to. I was thinking power steering or transmission cooler....does the car have a transmission cooler for the auto?
Look very similar
Filter should be on right side of the picture
Take a light and look down in the ending from around that corrugated plastic/rubber pipe (air intake) which is going in to theprottle body.
Filter should be visible and most likely white in color
I stumbled across this thread when I was looking for an alternate OEM filter. And I wanted to address this post;

There are a few parameters to consider such as oil flow, micron particle size, bypass pressure etc.
High Performance engines
The Ford Racing CM-6731-FL820 filter is OEM for modern Mustang V8s, which (depending on application) often make more power than a DB9.
Flow rate and filter particle size
Summit lists the Ford Racing filter as 12microns. No idea what the AM filter is rated at. But this is just like with air filters, its a trade off. The smaller the filter particle size, the more restrictive it becomes to flow. I've heard that you can find extreme filters that go down to something like 1 micron. A red blood cell is about 8 microns. So some oil filters out there will be able to clean brand NEW oil!
Bypass pressure
This number is not important. The bypass pressure value, is the pressure needed to bypass the filter element because its full of dirt. Its like a safety switch to prevent the filter exploding when its full of dirt. It tells you nothing about how much dirt the filter can hold, which is more important. If you're doing 10,000 mile oil change intervals then you want to maximise the dirt holding capacity of the filter, typically measured in grams. The bypass pressure value is not relevant.
In my opinion the Ford Racing FL820 is the best oil filter money can buy for the AMV12. Period. I'm happy to be proved wrong if someone out there is willing to cut up, measure and test a genuine AM filter. There is enough measurement data out there that we could probably figure out who the manufacturer/brand really is.
