Re: oil and oil filter change [melanjian] by ceric

The cost of oil and filter change is only $28 at my Mazda dealer. I would let the professionals do that for that kind of cost. The parts (oil and filter alone) cost about $15-$20 already (with all OE parts). What is the point of saving $5-$10? To each one's own, I guess.
 
For synthetic oil. It servces several purposes
- it endures heat better. Good for those who bring their vehicles to the track often to race in high speed.
- it lasts longer w/o breaking down. Good for longer interval between oil change (say, 10K-15K miles). However, the oil cost is 3X higher than regular one. Therefore, you don't really save much $$$ that way either.
- it lubricates better especially at cold starts after long period of parking. How often do you do that?! If you change your oil regularly (say every 5000 miles) your CX9 engine will last long enough. Your transmission probably will fail before your engine does....
 
So, you decide whether you need synthetic or not. It is your money and your CX9.
Some poeple baby their CX9s more than other.

Hi
Does this hitch go below the bumper?
and if so, does it lower the rear height ie can you
accidentally bump this on a steep drive?

Yes, the aftermarket hitch is 3" lower than the bumper.
Google the image "CX9 Hitch" and you will see at least one picture.
The picture is from an installation video at etrail.com.
You can find the OE installation at here
www.mazdaparts.com -> go to CX9 and see the accessories.
 
However, the OE one is 2 1/4" while the aftermarket only carries 3".
To each one's own. I like the 3" opening.

Hitch Wiring for 2009 GT AWD by pcz0925

What is needed for hitch wiring for the 2009 CX-9 GT AWD? It is set up and pre-wired for towing by Mazda and I want to install a Hidden Hitch and do the wiring myself if its pretty straightforward. I've seen on several forums that there is one connection to make and I've also read where other individuals are running wires to the battery among other places - can anyone simplify for a very NON-mechanical person? Any help is much appreciated!!!

2009 GT AWD has the "Tow Preparation" done even if you don't have the hitch. The wiring should be at the rear end. There is no need to run wires from battery to the rear. This is different for 2007 and 2008 models, in which you need to have the tow package to have the wiring prepared.

It depends on what you are towing. If your trailer has a 4-pin connector (for light trailers without brakes), you have everything you need in the factory towing harness and do not need to run any additional wires. If you are towing anything that requires a 7-pin connector (heavier trailers which have brakes) and plan to actually use the trailer brakes, you WILL need to run additional wires back to the engine bay. The CX-9 does not have the factory wiring to accomodate 7-pin connectors.

Ceric,
Please forgive my ignorance. When you state that the wiring should be at the rear end, do you mean under the car and if so, what should I be looking for?

The wiring harness is tucked against the back of the vehicle on the right side, underneath the rear storage compartment.
 
Take out the two little pins holding it in, and the entire compartment comes out..
 
Then look under the harness against the body, sort of underneath the tail light... its a 6 pin white connector taped to it. You can use a voltmeter with ground on the black pin, and map out the remaing pins (tl, tr, brake, running lights, etc)
