Nice, and good choice on the oil. You can square another 0.2 quarts in there just for good measure (it calls for something like ~6.13 quarts). That's the same oil filter as I use (look at my signature). In fact, I just bought 12 of them for $112 shipped from a Florida dealer. Turns out that they're cheaper for KIA than Hyundai, so I'm going to use KIA filters from here on out. Your old filter looks fine. Mine was sparkling in the sun when I did my first oil change, and there were particles in that plastic housing as well. Took a while to clean everything. Let me know what kind of fuel mileage you're getting with the new oil :)

Yeah I added a bit over 6qt. I just eyeball the "gauge" on the side of the jug. Give me a few days to come up with a reasonable MPG estimate... I had to go flog it a bit after I warmed her up :)

No way on earth anyone could detect and ascribe a real-world fuel economy change to the oil. Considering that gasoline varies in energy density by up to 4% even at the same gas station that puts a much smaller change down deep into the noise. Add in all the other vagrancies of daily driving and any observed change is impossible to attribute to one isolated variable.

The problem is not measuring something, the problem is ascribing it to one variable which in this case is utterly impossible.

I agree with you. Still, I was wondering if @SilverFusion2010 will experience any meaningful change. IMHO, he won't. The Mobil 1 FS 0W-40 is basically 0W-30 in disguise. In every VOA I've seen of this oil, the cSt @ 100C is towards the top end of a 30-grade oil. I think that's why it lost its BMW LL01 certification, along with Castrol, Pennzoil, and other 0W-40 oils. It's almost like all of these manufacturers decided to make 0W-40 thinner when they reformulated it a few years ago and either shear down to a 30 grade as soon as possible or ship it as a thick 30 grade in a 40-grade bottle as Mobil does.

We really haven't seen the viscosity degradation with current Mobil 1 0W-40 have we? That was a while ago, at least one or two formula iterations.

The approvals are based on HT/HS anyway, not a grade.

Just bought a 2021 Kia K5 GT. 2.5L turbo making 290hp. On prior vehicles I ran fram ultras out around 7500-10k miles. This one requires 3k changes under severe service... and since I'm enjoying the 290hp...

Basically, should I go with the orange can fram and save myself some money, or is it worth shelling out for a fram ultra every 3k?

EDIT

Fram doesn't offer a filter for this engine. Just finished up a live chat. So now I need filter recommendations. TIA

If this engine is a GDI, check for fuel contamination in the crankcase. If you encounter a fuel odor or have the oil analyzed and find over 2% of fuel in the oil, follow the 3k routine.

It's a GDI/MPI engine, so fuel dilution isn't as bad as it used to be with previous GDI-only Hyundai/KIA engines.

Right, so Castrol EDGE Euro (API SL) 5W-30 with an HTHS of 3.5 carries a BMW LL01 approval, while Castrol EDGE Euro (API SN) 0W-40 with an HTHS of 3.7 doesn't.

Actually looking at this: https://360.lubrizol.com/Specifications/BMW/BMW-Longlife-01

It seems that it's viscosity-related, as only 5W-30 and 5W-40 oils can get LL01 now.

All approvals specify a minimum HT/HS but that's not the only criteria for approval. My point was that it's not based on the grade (some approvals are starting to disregard grade) and neither is it based on a winter rating. There are many criteria an oil has to meet for an approval. To say it is "viscosity-related" and then infer it is related to the winter rating is not based on anything factual. Even if you wish to promote the notion it is for wide viscosity range oils that wouldn't apply to a 0W-30 oil as opposed to 0W-40.

Cartridge looks fine, wonder who makes it for them? Mahle has made H/K cartridge filters on other models, eg. 3.3L engine.

What was the oci/fci?

The aftermarket will catch up, though if history an indicator, some will just use the oem in their branded box. At least for awhile.

The aftermarket hasn't yet caught up, it's not a money maker I guess. Too many pieces to include in the kit for most manufacturers that are used to the easy money that a regular spin-on filter brings in.

Yeah, economies of scale keep cartridges higher than spin on anyway. Until and unless the application becomes popular enough to manufacture or rebox, they may not wade in. Fram reboxes the Mahle H/K OEM for the 3.3L engine. Extra Guard CH10855. Same cartridge.

A friend has a stinger with dual turbos. Purchased 2 years ago and couldn't find oil filter. The stealer recommended semi-synthetic or full synthetic. They didn't really know or care. I e-mailed Fram 2 years ago. Your not the first. Best of luck!

This has been interesting info.

I am looking to get a new sedan, and was hearing good things about the car, but the fact that they want me to spend $$$ on syns/filters every 3k miles in today's world is ridiculous. Admittedly, I'd probably not follow that OFCI after warranty, but my local dealers offer the "10yr/100k mi" warranty to first owners as part of purchase, so that's 33 oil/filter changes at a very high price point. If the fuel dilution is that bad, such that it needs flushed every 3k miles, then I'll pass for sure.

Man do I ever miss my old Grand Marquis ...
