Royal purple filter, 9.3k mi

[oil pan 4]

2 oil changes does not disappoint in the sludge department

First oil change was Pennzoil Platinum 5w30 ran 5,704 and the second oci was Pennzoil Platinum 10w30 HM ran 3,625 miles.
Hyundai sonata hybrid 2018.

Imasay that about the limit.

A little hard to see, but it appears as though that is a whole lot more goopy oil than I've ever seen in my old Sienna "sludge monster" with almost 475,000 miles.

Assuming that's the case what do you think causes that?

What filter went on? Thank You

A wix 51586 I think it was

I don't know but that sludge has topography.
It seems the harshness of being a direct injection, chain driven dohc engine.

I ordered a particle count on that second oil change. It was too dirty to get a particle count. So probably shouldn't run these for 9,000miles.

Wow! That is hard on oil for sure! I run my Promaster (Pentastar) 2500 work van 5k OCI with the OG Fram Ultra every other OCI. This is a small hard working DOHC engine for a heavy 159" wheelbase cargo van. Port injection seems to keep oil much cleaner, as the filter never looks that bad after 10k

Probably leaking leaf spring would be my guess.

Leak gap was probably too large for the debris to clog, lol.

The first oil change the oil looked great. The second oil change it looked way worse and only had like 2/3 the mileage.

 

[Fair enough]

Well oil filters don’t cause sludge. The oil looks ok like on the end cap and where it is thinner in the can. So the dirt stayed in the filter or can which is desirable.
Not bad maybe look at that new Wix XP they came out with.

Are those miles the miles the engine was actually running when not on battery?

So this was two relatively short OCIs and the oil was too dirty (ie, too dark) for a particular count on the 2nd OCI that was only 3,625 miles, wow. How many total miles are on this engine?

Who claimed oil filters cause sludge, lol. Only the debris you can see stayed in the filter. Nobody can "see" what's in the oil but a particle count which couldn't be done because it was too "dirty" or dark for a regular ISO 4406 particle count. Must be a lot of combustion blow-by going on to be that dark in 3,625 miles.

It doesn't seem to matter. My original hypothesis with hybrid cars is the starting, stopping, cool down periods would be easier on the engine oil.
All testing and observation appears to point to quite the opposite.
It would appear that hybrids are far harder on oil than straight gas cars especially in short trip cars.
There's only 57,000 miles on it.

Does this car show how much run time was on the engine over the OCI to give an indication of how much was on battery and how much was on the engine actually running. On a hybrid, there could be way more mini "cold starts" going on, which could mean lots of fuel dilution and ring blow-by with rich sooty combustion episodes.

Nope the hour meter counts up when it's on. Already tried that.
I've heard other non Hyundai cars will count hours only when the engine is running.

Just way too much time with same oil filter. I don't understand why or the logic. Why to over extended the oil filter eludes me.

What was the time period? ... didn't seen any info on that from the OP. Two separate relatively short OCIs mileage wise.

For soyance.
I'm finding that putting a big old wix wl10058 on my little ford 4L is able to just absolutely soak up the dirt.
I'll run it and pull a sample and find almost nothing and I'm at 8,000 miles.
The royal purple oil filter technology just isn't designed to run for a long time..
I'm just going to pull a sample every 500 until I start seeing more dirt. Then I'll either change it or run it another 50 miles and check it again.

 

[ZeeOSix]

Why not just an oil blot test, as I'm assuming you're not going to get a used oil analysis every 500 miles.
