It is not easy, and really is not a DIY job if you aren't mechanically inclined. You can change 2-3 plugs. You have to take off the intake manifold, which means replacing the gaskets. And there is a high chance of oil leaks.

Change your oil/filter and reset the light.

Just did an oil change on one tonight. I work at Goodyear. It's located close to the front bumper almost right next to the radiator on the left side of the vehicle. You have to take the cover off to get to it and drain the oil. Just take the two 14mm bolts off to access it. Hope this helps.

Warning lights come on when there is an issue. A Oil change light with turn off when an oil change has taken place.
Recommends a 10-30 weight motor oil for its Montero sport model. A heavier weight oil can be used in extremely hot climates.
you have to take off skid plate first to access oil drain plug, and to also get at oil filter. Make sure you dont drain transmission by mistake.
