17 Civic 1.5T, 108K mi; Pennz Euro L 5W30 9.5k mi

[chinee]

This has been the highest interval between oil changes with this car and the UOA still is pretty uneventful, except for the slight uptick in Fe.

Replaced with 5W30 Euro L once more, which is likely to be the final use of Euro L, only because I've run out. I use either PP or PUP 5W20 in my other 2 vehicles so the Civic will likely start on a diet of the same. I'm going to target 8 or 9K for the next interval... not ready to go 11K as suggested.

Car also got:
- new wipers, only 2nd time changing since new,
- battery, replaced free under 4yr warranty, Duralast Platinum (35 months ago)
- rear brakes, Carquest Premium Gold ceramics lasted 30K miles, replaced with same.

I wish I had more interesting stuff to post, but my cars and their UOAs are so boring, which translates to reliable and low cost.

What oil filters have you been running ?

At first glance it looks like the Euro L held it's viscosity better, which is probably the benefit of that oil compared to others.

At some point your oil consumption could spike due to rings getting dirty. I wonder which of these oils would keep rings the cleanest....

5W30, 5W20, 0W20, Euro, Platinum, Ultra Platinum, doesn't matter. Wear is the same. Your car is a Honda Honey Badger.

Either the Mobil 1-110A or the Purolator 14610.

Where is the Manganese coming from, I wonder?

 

[JAG]

That is a lot of data. Thanks. There are some mysteries with many of the viscosity and fuel measurements. Oil Analyzers is the lab to use, in my opinion.

 

[Oliveoil2]

Do you use the OLM for the OCI?

UOA is NOT an analysis of an engine; it is an analysis of oil! It seems this needs to be repeated at least once a week.
Cheap UOA cannot tell you what impact one or two OCI has on an engine. Only way UOA can tell you something is up with an engine is if there is huge spike in certain metals.

Stay with Euro L. It is a better oil than others.

I would agree. I was thinking of switching to a high mileage blend, but if it broke... so the yellow bottle will continue to decorate my garage for the foreseeable future.

That is odd. There is some information I left out concerning this oil change...

97,957... took an oil sample through the dipstick tube and sent for analysis. it's the prior UOA on the chart.
98,475... I tried performing an intake valve cleaning by spraying almost an entire can of CRC GDI IVD Intake Valve and Turbo Cleaner in the intake tube. Approx 1/3 to 1/2 of the can pooled in the intake tube and did not make it into the engine. Such a failed procedure... smh.
98,603... 128 miles and 4 days later, I changed the oil, which presumably might be contaminated with the CRC and any build up that might have been dissolved.

This sample is the oil fill that directly followed the attempted valve cleaning. Might the Manganese have come from the cleaning?

Possibly. From what I've read, Manganese is typically associated with a change in fuel type or fuel additive. You can see it's been creeping up over the past several oil changes.

Looks good... Thanks for sharing. If you want a slight bump in viscosity try a high mileage oil like you said.

 

[ARCOgraphite]

Did the OP use and octane enhancer or run cheap 93 octane? Most Likely from washed ash deposits from MMT.

Not something you want in a modern engine.

Also I would stick with SN+/SP oils in a tiny turbo motor.

Regular Top Tier fuel only.
