HONDA 0W-20 syn / Honda CRV / 1.5L DI turbo / 5k miles

[tyman]

It's a decent forum overall, just strange that a forum for discussion of different areas of concern doesn't allow discussion of one of the hottest topics pertaining to the CRV. I solve the issue by not contributing too much there. Interestingly, I've had similar UOA's to the ones here with both Mobil1 0W-20 AFE and EP. After several discussions with my Honda dealership and my Honda Master Certified Technician, they're having no issues, warranty or operational with my changing to Mobil1 0W-30 AFE, so that's what I've done. Observed no difference in operation or fuel economy. Planning on a UOA at 3k to see how it's doing, my hope is for 4-5k OCI's. My Technician indicates that a LOT of Hondas with the 1.5t come in with oil high on the dipstick, so a forum that puts it's head in the sand and pretends or insists the problem doesn't exist, isn't providing a true forum, obviously an agenda there for what reason, I don't know.

Like I said, I really think he's a corporate shill/employee for Honda. That would explain 99.8% of his posts on the forum and the behavior of the forum in general.

First UOA on my 2017 CR-V as I was a little concerned about the reported fuel dilution problems with the 1.5 turbo DI engine.
The UOA showed 3% fuel. I have not noticed a rise in the oil level and none of the previous oil changes smelled like there was a lot of fuel in the oil.
I am sticking to 5,000 mile OCIs which is about 30% on the OLM.View attachment 61851

Bump...due to relevancy to recent contentious discussion.

Can someone please explain to me what the problem is with this UOA ?

I am looking at wear numbers, fuel dilution % and flashpoint (est.)

TY !

No problem with it. Just diluted oil and reduced viscosity. Run 5w30 and be happy

Fuel dilution is a third rail topic. Don't ask me how I know.

So a certain percentage of fuel dilution, with a certain flashpoint, is cause for alarm, never mind the wear numbers ?

There is "some" fuel dilution and there is "severe" fuel dilution. Why not have consideration for the other data points ?

Thanks for responding parshisa.

A $30 spectrographic analysis is a poor indicator of engine wear. Just like flash point is a poor indicator of fuel dilution.

The actual ASTM test for engine wear due to the oil is a far more complicated and expensive endeavor. But it gives statistically valid results.

5yrs and 63K miles with civic and 0/5w30. Several UOA with “normal” wear numbers on “heavy” oil. Car DOES NOT CARE. All the engines cares for is how regularly you’ll be changing it.

93 octane fuel will take care of majority of the fuel, when I used 87 octane I would find fuel in the catch can, oil also smelled horrible of fuel. I could actually smell it in the cabin. I switched back to 93 octane and no more fuel in catch can. I also use Mobil 1 ESP 0w30 ACEA C3 oil. Oil analaysis showed 0.8 fuel over 10,000 miles with the 93 octane. With the 87 octane it was 1.8 fuel dilution.
