2.3L Engine oil

24351 Views 23 Replies 13 Participants Last post by  ddsski
Looking through the MKC owner's manual, it indicates an oil change interval of 10,000 miles or 1 year, as long as the intelligent oil life monitor (IOLM)hasn't displayed a message to change the engine oil. But if your IOLM resets prematurely you should change the oil at 5,000 miles or 6 months.

How do you know if the IOLM reset prematurely?

Page 341 shows the 2.0L's oil capacity (5.7 qt.), oil type (Motorcraft SAE 5W-30 Synthetic Blend or Full Synthetic Motor oil), and Ford part no./spec no. Nothing about an oil filter.

But page 342 shows the 2.3L and it's Engine oil capacity and spec is completely blank! Whatsupwidat?

Do these engines use an oil filter?

Go download the 2016 manual. It shows the 2.3 specs. Same amount of oil as the 2.0 and they both use same filter FL-910-S (also listed in the manual).
Seems that Ford specs indicate same oil capacity and oil for the 2.3L as they do for the 2.0L.

Oil name:
Motorcraft SAE 5W-30 Premium Synthetic Blend Motor Oil or Motorcraft SAE 5W-30 Full Synthetic Motor Oil

Oddly enough the part number is different. For the 2.3L the part number:
CXO-5W30-LSP12 or CXO-5W30-LFS12 (Canada) / WSS-M2C946-A

Taken from Ford Technical Specifications.

And a one page pdf that describes the MKC 2.3L engine.

And the oil filter is a Motorcraft FL-910S, as per p 337 in the 2015 manual:

The interval between oil changes varies based on driving conditions, etc, However, I prefer to change oil every 5,000 miles. To me, 10,000 miles is just too long.


Besides, I like a professional pair of eyes doing a safety check (tires, brakes, etc) every 5,000 miles while performing the oil change. I guess our dealer agrees. They are offering FREE oil changes every 5,000 miles for the life of the car!
That's nice, when I was going to buy the Audi the local dealer was giving us free oil change and basic maintenance for life of car too..
Did you buy from Kindle in CMCH by chance? I saw a lot of MKC's from Kindle this summer actually...

I asked my dealer about the conflicting oil change intervals too and they said 7500 - and they did the other basic maintenance stuff too.
Moretti.. We dealt with Causeway Ford/Lincoln in Manahawkin NJ. they also say that the "recommended" interval is 7,500 miles, not 10,000 but provide the oil change at 5,000 miles. Seems strange but we will change every 5,000, with or without the FREE offer.
Yeah, I was hesitant too and thought even for synthetic oil 5K would be it but they did oil change and basic at 7500 and say next oil change isn't until another 7500 which would be 15K. I used to change oil every 3K with other cars!

Hope you guys make it through the hurricane OK this weekend! Where is your MKC gonna be? Get it to higher ground if you're by the coast. Sending good luck your way, be safe!
Just want to thank all for their comments, references, and advice re: Engine oil and the 2.3L.

Thanks. My wife is on her way to Nashville with the MKC to see our son, daughter in law & (2) granddaughters.


We are 12 miles from the beach, so hopefully we will be OK even if the hurricane hits the Jersey shore.


Take care!

My dealer completely contradicts the manual and marketing materials about the free oil changes. He showed me on their internal Lincoln technical web site that we get a max. of 3 free oil changes and tire rotations over the first two years. I don't put many miles on my cars so that equals an oil change every 8 months. For your car I guess it depends on how many miles you drive.


I always get my first oil change (after the engine has been broken in) early, at about 6 months or 5k miles, and then stick with the regular intervals. My last 3 cars have all used synthetic oil and I've consistently been told by the respective Service Mgrs. (and backed up by the car's manuals) that with synthetic you can safely go 8-10k miles between changes, and I have. Of course once the free oil changes expire, the price for an synthetic oil change vs regular oil is about 3x the cost...$20-25 vs $75-90 where I live.

Usually with new cars, I change the factory fill at 5,000 KM...I also use regular oil for my second fill,beyond that, I change to Mobil 1 full synthetic.
Wondering if we get first 2 years free oil changes here in Canada...anyone Canadian knows anything about this, please share, thanks!
Question. If I want to top-off my oil on the 2.3 ecoboost do I fill it to the top hole on the dip stick or just above the hash-marks? Or does the hash-marks indicate time to add oil?
I always just aim for the hash marks Blankster, just a smidgen below, don't forget oil takes it's sweet time to move down to the pan,so the initial reading is somewhat skewed ...top to bottom of the hash marks is the "safe "range....too close to the bottom and you'll froth it..stay closer to the top, hope this helps!
The owners manual seems to indicate that between the holes is the safe range. I'm Just topping it off before we leave for a trip out east. To me it looks like the hash marks indicate the lower half of the safe range.
I have 6 qts. of Castrol full synthetic 0W30 from when I owned my Saab who recommended it for turbo longevity. Volvo and Mercedes also recommend it.
Would it be OK to use this in my 2.3 Ecoboost?

No. I would use the proper weight oil. In fact the head mechanic at my Lincoln dealership suggested sticking with synthetic blend as opposed to full synthetic. Now for those of you in Canada perhaps the factory fill is synthetic??
It gets pretty cold and snowy here in Syracuse. Mobil 1 5W-30 and Motorcraft oil filter for me. I change oil and filter my self every 5000 miles. May be overkill, but that's my choice.
As a Racer, the oil topic is something I don't get personal with. When hot, the 30 is what matters. OW would be my oil of choice for winters esp if you will be starting at or below zero routinely. That oil is 100% acceptable and WILL NOT void any warranty. Unless you live in the deepest south, I'd just use that standard. When I take over my oil changes, that is the weight I will use. Its the 21st century, the only reason they use a blend at the dealership is because its cheaper. They want you d to do more frequent changes at the stealership. ALL of the European vehicles are using AT LEAST 10,000 intervals between changes (many unlimited mileage annual now) on top shelf full synthetic oils. LL01 spec, or LL04 spec on BMW diesels for example.

For all we know, the head mechanic is 60+ and hasn't been reeducated in oil tech in 25 yrs. :eek The very first motors to benefit from true synthetics were the turbos and this goes back 25 yrs now!!

Dealerships just preach the manual according to Ford. Blank on this one, I've run motors way harder than 99+% of y'all will ever do. I've done massive amounts of research on the topic. If Op had said 0W-20 or 5W-20 I would only have agreed with that if he was in canada and it was for winter use. But by and large I would suspect the 20 would be a bit thin for the pressures that would be seen in the motor.
In my Lotus motors, I actually use Shell Rotella T6 5W-40 (a diesel oil) because the higher zinc levels prevent cam wipe and at WOT, I'll burn everything right off the cats. Delvac was also top shelf.

In the beginning, Mobil 1 was a true synthetic type 4 I believe. Then Castrol cut corners with a type 3 synthetic (basically a blend). Except for the extended performance products, Mobil 1 isn't that great anymore.

THose overkill oil changers need to look at the studies. Your 500 mile oil changes may get you 325000 miles while the annual or 10000 folks only get 300000 out of the motor. Add up the costs and you might as well just replace the vehicle 6 months sooner.

Nothing like an oil thread to stir up passions among gearheads...

When a dealership or car company recommends a specific brand of oil, you can bet that they have a financial interest. If either advocates for dino (conventional) or synthetic, you have to look for the reason.

Case in point - BMW Mottorrad (motorcycle division) made a sudden recommendation change from full synthetic to dino for their bikes around 2005. The reason was widely discussed on various forums until someone noticed that the change happened at the same time BMW Motorrad switched their oil supplier to a partner that did not offer synthetic grades. It wasn't a realization that full synth was bad for the engines, it was simply a matter of the new BMW-branded oil only being available in conventional grades.

One of my cycle club members is a lubrication engineer. His favorite saying is:

Dirty oil is better than no oil
Clean oil is better than dirty oil

If anyone tries to engage him in a debate on dino vs. synthetic vs. blends, he just defaults to the statements above.
