My car has hit right above the 2000 mile mark. It has already been through one day of autocross. I decided to change out to the oil a little early and send it out to sample for the sake of collecting data. I noticed my oil had a strange tint to it, similar to what it looks like when someone puts dye in it to inspect for leaks, anyone else notice this when using Motorcraft oil? Anyhow, here are some pics of something I thought was interesting. It seems like there are design differences with the factory original FOMOCO filter and replacement Motorcraft filters. Im not sure why they would be designed differently. If you look closely you can see the bypass spring is different along with the holes for the oil coming out the filter. This was something I found curious so I wanted to share this out to anyone who was curious.

Pic of the FOMOCO filter. You can see some of the residual oil and the curious coloring I was talking about. I have no driveability concerns but sending it in for anaylisis anyhow.

Motorcraft filter. I tried getting a good shot of the differences inside. If you look closely you can see the differences between the factory and Motorcraft.

I assume both filters had the same oil per-filter change/oil change? Also same driving style per-oil change filter change. (this would be inconsistent due to being human.)

This was the vehicles first oil change so this oil that came out was the factory fill.

Yea the motorcraft oil has a green color.

 

[galaxy7]

Yup...my first drain was that odd color as well. No idea what they do diffeeent, but it's normal.

The factory oil has additives that help with break-in. It should be left in for the first 1000 miles at least.

Some of the differences would be for service departments to be able to see if the oil was ever changed during the warranty period. A part from the external markings being different between the factory and OER replacement filter the design difference on the inside would also tell them if it was changed.

A little bit of leak check dye in the factory fill oil doesn't constitute a special break in oil, in fact the owner's guide says not to run any special break in oil or friction modifier as they may prevent piston ring seating.

Its breakin oil

There's no such thing in modern engines.

Next time go with M1-211 (similar to old ford 910 before they downsized it)

Personally, I go with the Mobil1 M1-209. Width is the same as the M1-211 (2.98"), but it's 0.63" longer (4.12" vs 4.75") and brings oil capacity up to a full 6qts, which is nice, as much as I love having 1/3 quart of oil on the shelf. It just absolutely dwarfs the newer, smaller FL-910S. Also, with that much filter media, you never need to worry about the bypass valve opening and having unfiltered oil circulate on cold startups or due to a dirty oil filter on a long OCI.
I'm doing a change this weekend and was actually going to take a photo just like yours and post it in a different thread, but you beat me to it. Maybe I'll still do it, just for fun.

 

[Huzzah]

Here is a comparison photo I took. Looks like the M1-209 and M1-211 are actually the same size (one wasn't in stock) despite the different specs listed on O'Reilly's website.

 

[aaronc7]

Interesting. I got the M1-211 last time around and it took exactly 6 quarts, which is what I was going for.

What's up with the gasket on the original?

Is there a taller Motorcraft filter to reach the full six quart oil change? Will the Fl-400S do that? Though I know there are some very good filters out there I want to stick with Motorcraft to avoid getting any possible grief from the dealer if I ever have an oil-related warranty claim. And I take it a taller filter fits fine, no issues with it hitting something or being hard to get into place or for removal? (My car is brand new, there is snow out and I have not crawled underneath it yet to learn where everything is. First oil change will be this Spring)
Not having the .3 worth of oil left on the shelf appeals to me too.
Thanks for any replies.

 

[Huzzah]

You'll be fine with 6qts and FL-400S. There are no clearance issues as the FL-400S and 910S are the same width, and the FL-400S isn't long enough to touch the splash guard. Even the M1-209 isn't long enough for that.

Congrats on the new ride, happy motoring.

So let me get this straight...you're worried about not running a Ford brand filter due to warranty concerns, but yet you have no concerns about running a completely different part number not recommended/listed in the owners or service manual??? Interesting.

Keep in mind that it's tendency to get wrapped up in the working about "meeting manufacturers specifications or recommendations". Most aftermarket products, especially something like Amsoil, exceed those specs.

I use an Amsoil EaO 34 which is the FL400 counterpart and exact same size. 6 quarts put me right at the top of the hash marks on my dipstick.

 

[NY STate of mind]

You make a valid point. I was only asking for the six quart convenience factor of it but while under warranty I will stick with the 910S. Might change to something else down the road some day.
