I recommend using Amsoil Signature Series Oil. I have had great success with it in my Wife's Infiniti, my old Equinox, and my race cars when I raced circle track. Amsoil oil and filters will be going in my Focus here soon. But everyone has their opinion about engine oils.

If you want to change your oil with the best, and use the oil safely for the OEM 10,000 mile interval, or one year....here is what I would do.

Amsoil ALM 5W-20

Amsoil EaO34 oil filter

This will give your engine a 5 quart capacity, better mpg, less wear, and peace of mind knowing you can take it for the long run.

and don't pay retail for it. Take advantage of their preferred customer program.

I didn't take the time to read the entire, but I'll add my thoughts on the matter anyway.

I used to run exactly 3000 miles and change the oil. If I was over a bit, I'd freak out and think my engine was going to blow up. Guess I was pretty naive at the time.

When I got my jeep and decided to switch all maintenance / most repairs to ME, I started reading up on oil. My 4.0 is an "old" designed engine with not-as-tight tolerances as modern engines. Anyway, the common theme was that it is safe to run 5000 on synthetic on that engine.

My 2011 Focus' owners manual suggested 7500 miles OCI. At first, I wasn't entirely sure whether or not that would be a good idea. When looking at used oil analysis for this engine, I think 7500 on a synthetic would be entirely reasonable. Maybe even 10!

There's a few reasons why it's able to go 7500-10k miles. First is, it has a larger oil capacity per liter of engine than my Jeep. It's oil capacity is 5 quarts, my Jeep's is 6 ... it has half the engine displacement. Second, as with any "modern" non DI engine, it has tight tolerances and isn't hard on oil. Until recently, I had been doing it at 5000 since I qualified as "severe service".

Since my last oil change, I've had a ton of highway driving, I'm going to try to extend it out to 6500 this change. I need to keep it within owners manual specs for warranty purposes.

Once I get out of warranty, I'm going to do two oil changes a year. One in November switching to 0w-20 and one in may/june switching to 0w-30 - it should be about 6000-8000 per change. Oil filters will be changed haflway through the interval.

Now, DI engines may be a bit different. Since they're new, the affects of using oil longer aren't entirely known. They do tend to be a bit harder on oil and have more fuel dillution. If I had a DI engine and was going to do an extended interval, I'd do a used oil analysis at 6000 to see how the oil is holding up.

As a side note... If you're not already using a larger filter for higher capacity on your 4.0, you can use the filter for Ford small blocks. It cross-references to Motorcraft FL-1A. It looks like you might already be doing this since you mention 6 quarts, but I thought it was worth a mention...

You can't beat a UOA for gauging the efficacy of YOUR engine's OCI. It will be interesting to see what the internal monitor thinks of my Amsoil fill. Wonder if it will trigger the "change soon" at all before I chicken out?

Factory fill gets dumped this week @ 3500 miles. Will get UOA at 10K at a max for the new fill. Will base OCI's on the 10K UOA.

Yup, I've been running the FL-1A since I have done the first oil change!

It's thrice the size of the stock mopar filter ... I think the huge filter caused the oil filter adapter to leak from bouncing around off road with almost an entire quart of fluid! haha. To fill my jeep from empty on an oil change is right around 6.5 quarts.

The last oil change was with Rotella T6 and I ran it 6000 miles. I'm going to change my Cherokee to Supertech synthetic 5-30 in November/December (whenever it starts getting cold). I'll probably have a total of 7000-7500 on it. I'm going to do a UOA then to see how it did!

Aren't the OLM based on mileage, throttle usage, trip length, etc?

I really don't know. There may even be a particulate sensor in there that triggers at a certain level.

Or, it could be like the filter change light in my fridge. It alarms regularly(every few months). Of course, it isn't hooked up to anything, so it's only telling me that a certain amount of time has passed since I last reset it
