Mobil 1 ESP 0w30 5500mi 2024 Integra Type S K20C

[bvl]

Third UOA, similar trend in the viscosity dropping a tad.

Oil Analyzers did the UOA, only surprise to me was the low Fuel Dilution reading. Don't know why they feel its flagged as a different oil, the add packs are pretty close which is expected with the ESP 20 and 30 here (vs. the 5/30 API spec)

For my driving (good amount of 65-75 HWY), running the 20 or 30 for 6K OCI would be just fine, I do like the added HTHS of the 30 of course. I am not afraid to dip into the happy pedal on this fella, that's why I got it Will run the 0/30 for 7500 for next UOA.

Looks like they didn't test the fuel via GC method like your previous two samples (Hence why it's showing low). Metals are coming down.

strange you got more aluminium than iron the samples.

I question the 1% fuel dilution, with a KV100 of 10.1 only

Is this a Turbo Engine? Maybe Honda finally fixed fuel dilution

I think fuel dilution is low considering he has 10cSt viscosity for 30 oil

That Euro 30 grade oil is quite shear stable. We've seen other oils where you'd think that it should be less b/c of the fuel dilution but it's not that low so viscosity alone can be misleading. I know what you mean though.

I had the K20C in my 2.0 Accord and my current car 23' CTR. I done numerous UOA on these cars and have never seen excessive fuel dilution with this Honda engine. Although probably 70% of my driving is open road and expressway. I do very little short tripping during my commutes.

Well, K20C4 has issues

This is from Oil Analyzers:
"When the oil's viscosity is lower than one (1) cSt from the known starting viscosity of the oil when new, we will confirm fuel dilution by ASTM D7593 GC method, reporting the result as percent by volume. However, if lubricant grade is not included with the sample, fuel dilution will be confirmed by GC if viscosity is below 13.3 cSt for diesel engine oil and below 9.8 cSt for gasoline engine oil. If viscosity is above the oil's mid-point for the grade, fuel dilution will be reported as <1.0%."

It seems that since you don't have a VOA of this oil with a known starting viscosity, they defaulted to the "below 9.8 cSt" and did not do the gas chromatography. I have started putting a note on all of my samples: "please test for fuel with gas chromatography regardless of the oil's actual viscosity." They have honored that request every time. You just have to tell them.

Yes, @tolian21 its a high boost 2.0T, minimal difference in the Integra Type S I have vs. The Civic Type R. The K series doesn't dilute as much as Honda's L15 series, but there appears to still be more then trace amounts in relatively short drain intervals (Honda would have me go 10-11K based on their OLM)

This is my first 30 sample, the previous 2 were 20s all started in the mid 8's for cSt (M1 EP 0w20, then M1 ESP 0w20).

Thanks for that note @himemsys. This is a bit annoying since I specifically put in the notes that I was looking at fuel dilution for this sample. Guess I didn't use all caps so the common sense-o-meter would go off

Check other people reports for 2.0t, including mine, all high dilution. And for highway driving.

Considering ESP 0w-30 started at 12.0, its not bad to end up at 10.1. I get about the same viscosity loss due to fuel dilution, maybe a bit more 2.5cst
