What is that a picture of? I don't see sediments in a pan.

Thanks!
That stuff is big enough to get trapped in the filter. It was probably sitting in the pan away from the pickup so it wasn't moving much until you drained it.

GDI ? Typically GDI engines may not do so well beyond 5,000 mile oil changes due to the amount of soot dumped in the oil (not so good for timing chains).Surely you must be kidding
I regularly do 7000-7500 mile intervals in my Corvette and 10,000 mile intervals in the Civic, using off the shelf oil that can be found in Walmart and Canadian Tire.
5000 miles is too early for most people unless it’s a severe fuel diluter. Even with a little bit of fuel, 6-7k intervals are fine. There are plenty of high mileage 1.5T Hondas out there chugging along just fine using intervals determined by their OLM (which means 9-10k)

There’s no reason why it wouldn’t make it that far with 10k intervals. It’s port injected, it’s easy on the oil and I do mostly long highway runs. And long term members here will know that Tig1 has done 10,000 mile intervals with Mobil 1 for almost 50 years now and many of his cars went well beyond 300k.

My Corvette is direct injection but doesn’t have a problem with fuel dilution at all. My Civic is port injected.
Our Honda Fit has averaged between 9k and 10k mile OCIs and it's over 360k miles now. The MM typically recommends replacing the oil around 7k miles, but the assumption among owners is that the MM is based on it guessing you are running conventional oil (this is a 2007, it's not the most sophisticated oil monitoring system). Still, it's also mostly highway driven and is easy on the oil (PI) which means extending the interval isn't an issue. As always, OCI based on mileage is a case by base variable. Shorter mileage isn't always necessary and may be a baseless recommendation entirely for many cars and service conditions.

As I've said before, hours are a much better proxy for this stuff than miles. A DI engine short tripped in-town like a Honda 1.5L could have a gallon of gas in the oil after 2,000 miles and 200 hours with an average speed of 10mph, while the same car driven 90% highway with an average speed of 50mph would have accumulated 10,000 miles and not have the same gas in the oil.
How do you time changes this, if at all? What if someone takes 18 months to do 7500 miles?
Don't you burn oil? (I mean, you have 360k, so it's had a good run, but just wanted to point that out.)
Then 18 months! This 1-year thing is getting old!

I wouldn’t have a problem still taking it to 7500 miles in that case. In fact I used to do two year oil changes in my previous Corvette and one of those intervals ended up at 10,100 miles
But it wasn’t a fuel diluter. I’m not sure if that’s specifically what you were referring to
Yes that was it. Just wondering if time plays into your decision at all. I'm on the side that it doesn't really matter.
Yep. It burns oil. Bought it used at 156k. It has always burned some oil. When I decided to start tracking it (back when I was in my 20s and stupid), it has consistently been at 1Qt every 4k miles for most of the mileage since purchase. I don't know exactly how much it was burning initially upon purchase and I have no way to know POs maintenance habits. It may have been less originally.
Granted, that's a relatively small amount for a Honda I4 with this mileage. If it is somewhat stuck rings, I'm gonna find out before year's end as it burns more than before now on Valvoline Restore and Protect. Given how hard it's driven on the interstate, it could just be wear and blowby due to RPM revving to make power. (It's around 3500 for ivtec and yes the PCV system is working fine)
That said, to your point it may be stuck rings. If that is the case, it would be due to using cheaper OTS synthetics like Havoline Pro DS or Mobil 1 Advanced Fuel Economy too far; that's the oils I used mostly when I first bought it.
^In hindsight, Amsoil Signature Series would've been the correct choice. The UOAs looked fine on other oils for 9k and 8.5k, but who knows if piston deposits were occurring. It didn't seem to be much a thing back then. And under the valve cover, it looked exceptionally clean.
^So, we now know cleanliness is deceptive wrt piston cleanliness. Also the UOAs I got at the time didn't test for oxidation, though maybe that's a thing regardless because we do know deposits occur even early in an OCI, so who knows if it's the intervals or prior owner, or oil choice. Likely more the oil choice being an issue if it's deposits.
You live, you learn, but I can live with 1 Qt per 4k. I don't like that it has trended to 1 Qt per 3k on the Valvoline Restore and Protect though. I've got about 10k miles left to satisfy my minimums on Valvoline Restore and Protect. (20k miles total and over a year)

An initial increase in consumption when first starting Valvoline Restore and Protect has been noted by members here. Those who continued using it found it stopped and then things improved with subsequent OCIs of the Restore and Protect.
Valvoline Restore & Protect 5W-40 is officially on the Valvoline Euro website, but PDS/SDS are missing yet.

True.
It’s on the 3rd interval now. So far, the rate of consumption is the same as the 1st interval.
However, I’m not tied to any particular outcome, but not everyone that did the “minimum consecutive OCIs” had a reduction.
At the very least, I can rule out whether or not it has clean piston rings when I’m through with interval 4, and that’s good enough for me.
As stated a while back, if between now and the end of interval 4 I notice an improvement in the consumption rate, I will likely run a 5th subsequent OCI at that point.
The PDS are available if you select a European country (make sure you pick the UK unless you are fluent in another European language haha). Sadly they are not available in the US yet which makes me nervous they won't be released here.
If you search in the US:
