View Full Version : QX4 Oil Change Question

09-14-2004, 09:41 PM
I have to change the oil on my 2002 QX4. No, I didn't go two years without changing oil. LOL! I just bought it used in June. After a very quick peek it appears the skid plate covers the filter and motor. Is there a "trap door" or do you have to remove the plate in order to get at the filter?

No trap door. You've got to drop the sheild. You can leave front bolts attached and just take loose the rears.

Yeh, that's what I figured. I had bought a set of ramps for my old '03 Cobra and just haven't had a chance to get the QX4 up on the ramps to check out the undercarriage. Thanks for the help. I appreciate it.

This is my first time changing the oil for my '99 qx4. What oil filter is good for this car and is there anything tricky to doing it? Also, what kind of oil do you guys recommend? I just got tired of bringing it to the dealer to get this done.

I use Mobil 1 10w-30. Mobil 1 Filter works well also. If you have high mileage, don't switch to syn, it might leak.

I think the dealership uses Valvoline, so go for that if you don't use Synthetic.

thanks! so they use regular motor oil at the dealerships? I guess that makes it even easier. Well, it's at a little over 60k in mileage but if that's what they've been using, I don't know if now would be a good time to switch. And I looked up some oil filters on line and it looks like I might get a Purolator oil filter. I heard they work pretty good. Any other tips? Pretty easy to change? I've never really gotten down there to take a look. Figured it shouldn't be any harder than my Acura Integra.

Make sure you have a socket set (metric). That skid plate is fun getting off if you don't have the right tools.

I personally would change all the other oils to synthetic, other people might say otherwise. Such as transmission, transfer case, blinker fluid, etc...

I changed my oil at 40k to synthetic (when I bought it) and have had no leaks. But the best engine damage preventative is not what oil you use, but how often you change it.

Get a intake while you're at it, it'll add a little MPG and HP. I suggest a HKS for your car.

Thanks for the recommendations. HKS makes an air filter kit?

Oem, Mobil 1, Pure One, in that order and they should be replaced every 90 days [small size] 3,750 miles if you care about the after 100,000 mile performance.

I highly suggest the K&N for easy of installation. The others are nice, but need some tweaking (bends are not perfect, mounts are horrible or non-existant, etc..). For performance, Franken is suppose to give the most hp. I suggest the Apexi filter if you do go Franken.

Enjoy your QX4! I love this car!
