I was thinkng the same thing. I use the K&N filter on all my vehicles with Mobil-1 Synthetic.
Mobil 1 and K&N filters are one in the same. Better than your standard cheap filters, but for what they cost....you may have well as purchased the far superior Royal Purple or Amsoil EaO oil filters. Nano fiber > synthetic cellulose

Hey, that's great. Thanks for the pics and the info. I wasn't aware that K&N and the Mobil-1 filter were the same. I've chosen the K&N filters because of the .75" nut welded on top of the oil filter. On all my other vehicles, including my Harley, where the oil filter is hard to reach, having that nut has been a lifesaver. Although based on what I can see from this thread the filter appears to be easily accessible where the nut wouldn't be necessary.

I wonder, are the Mobil-1 and K&N filters priced competitively?

Not really, they are ~13.00 per filter. Most people use lesser filters to save money.

If I were going to spend that much, I'd go ahead and invest $15.00 in a Royal Purple filter.

Amsoil preferred customers get the EaO filters @ ~13.00

Yep. You're right. I checked AutoZone (see link) and it looks like the K&N filter runs about a dollar more than the Mobil-1 and the Royal Purple about $15.00. I found some good videos on YouTube also which shows the various filters dissected and truly the Mobil-1 and K&N appear to be the exact same internally.

I'd like to see a comparison of the OEM FoMoCo filter as they are the only ones I ever use on any of my cars
ask and ye shall receive *This is the MC filter that will match up with those posted above, not the exact filter that is built for the Focus*

If a oil filter is too restrictive it can lower oil pressure, just a note.
Depending on which side the oil pressure sensor is on. A restrictive oil filter can cause different results.

Sensor before the filter - pressure will rise due to restriction

Sensor after the filter - pressure will fall due to restriction

This is why I love nano fiber synthetic media. It's able to filter the best, yet still flow the best. It's rare when a single product can give you the best of both worlds.

Thanks 2012SEL for posting this. Just changed the oil in my 2013 S at 650 miles. I like to change it early to get any kerf (casting flashing), casting sand, gasket, or whatever unwanted material may be in there.

Same for me - went to a place back in '92 that changed the oil in my F-150 in a "jiffy". Friend drove it to the mall to pick up a couch and called saying it was making weird noises - she drove it back to my house.

The weird noises was a rod that spun a bearing, most likely due to no oil in engine. Turns out the filter was not tighten - and with only gauges and no idiot lights for oil pressure, she never looked at the gauges.

They offered me $200 towards the repair - "Prorated" as the truck was a '78 with 150K on it. Never a problem with it until THAT oil change.[bigcry]

Is there an oil life percentage on the 2012/13 Focus that should be reset?
Yes; turn the key on but not engine. Close all doors so no warning box on instrument dash. Press both brake and gas pedal for a really long time. Even if you think something is wrong keep holding the pedals. Eventually it will say it is reset. Forget the exact dialogue, but do remember it taking a long time to reset.

Got it. Thanks!

Instructions copied from the Owners Manual are at the end of the original post.

Hey guys,

I have been changing my oil on every car I have ever owned, as well as many friends cars... but apparently tonight is not my night.

I changed the oil in my focus for the first time tonight and the original instructions really helped. I got everything put back together and the car back on the ground. I put about 4 Qt into the car and ran it for a few minutes. I checked the dipstick and the oil was just at the bottom of the stick.

This is where i get confused. I added some more oil to top it up (probably half a Qt) and, after letting it sit for a minute, checked the dipstick. The oil was about half way up the length of the dipstick... [facepalm]

After walking around for a few minutes walking around in frustration, I jacked the car back up, took off the shield, drained about half a Qt of oil, and put it back together again. checked the oil when it was back on the ground, and it was back to what it was the first time, just at the bottom of the stick, not even into the hash marks.

I had learned my lesson the first time, and added almost no oil, and checked the stick... it was back up almost halfway on the stick (almost a foot over the max fill... [bigcry]

So, I ran the car for a few minutes, and am going to let it sit for some time to see if it goes down.

TL;DR
Is it VERY easy to overfill the oil in the focus, or am I missing something?
Thanks in advance guys, its been a long day.[?|]
