I have a 2006 Montero Limited. I use 5W-30 Pennzoil Plat. in conjunction with either Wix or K&N oil filters. My mileage is currently 33,500. Becasue the Montero's engines are overtaxed and work harder to pull the car around than say, a Land Cruiser, I think using a synthedic oil and frenquent changes are the best rules to follow.

Syn blend
Purolator Pure One Filters are good. Just avoid Fram since they tend to leak at the seals.
During break in periods your supposed to use conventional oil then switch to Synthetic. As for switching to conventional oil once in a blue moon after regular use of synthetic it should be fine since synthetic is a high detergent oil unlike conventional and there is alot less carbon build up in between gaskets. So if your in a budget crunch, going to conventional in a emergency is fine.
Now going from regular use of conventional with high mileage, there is going to be alot of old carbon build up in between old hardened gaskets, head gaskets, rubber rings, ect. So using Full Synthetic high detergent all of a sudden will do its job of cleaning carbon. So guess what, where the carbon used to be is now a hole or passage for oil to flow through and create to mystery leaks and puddles on driveway since the gaskets are old and not fill the gaps.
Alot of my friends did the switch to Synthetic after I warned them with their cars having 150k plus miles, now they have leaks all over the motor.

I've been using regular 5-30 oil (Quackerstate) from the day I bought my Montero. Changed both oil and filter every 5,000 miles (the book says to oil change every 7,500 miles on regular service and 3,000 for severe service). I figured I'm somewhere in between and it works very well. I'm not at 180k miles. I use only Wix or OEM Mitsubishi filters. As another post stated - stay away from Fram.
I truly do not think you need to be doing an oil change every 3,000 miles if you are running a full synthetic oil. You should be able to at least go to the maximum recommended mileage for the regular service (7,500). Definitely avoid going back and forth between different types of oils. Pick one and stay with it.
