Here's the latest report for my turbo civic. Same as the first report I had on it (factory fill), viscosity is down and severe fuel dilution is present. The only difference is that this time there was no increase in oil volume on the dipstick, it wasn't watery and didn't smell like gas at all. 95% highway driving. Shifting gears at least at 3-4K rpm. And oil is still diluted. It feels like that the car is tuned to run rich, perhaps to eliminate LSPI possibility. Wear numbers seems to be fine though. How does this report looks to you guys out there? Oh, and does oxidation parameter means? looks kind of high although not highlighted.

For comparison and info here's my first UOA on the Civic (Factory fill)

It can't run too rich too often without melting the catalytic convertor, failing emissions, and giving poor MPG.
Remember this engine is supposed to be very efficient with fuel! Its the game.
I think the ring sealing is not standing up to the extra turbo pressure, creating excessive blow-by. Common in Ford Ecoboost as well, probably many others of this type. Everybody has gone to DI-turbo engines now.

I'd be very tempted to use M1 0w30 since that would give more of a viscosity safety margin during fuel dilution for a long or medium OCI.

Blow by is very very minimal on this engine. I had a catch can installed and in 3K just a slight film on the canister walls and some residue on the bottom (perhaps 1/4 of tea spoon). And yes, it gets very good mpg but it's not the seals and not blow by. Thanks for your feedback though.

I'm leaning towards 0w30 on the next change but not sure on the brand yet. I'm comfortable with 5K OCI as long as wear metals are low.

If not excess blow-by in that engine, the only other way I can think of to get that much fuel in the sump is via a leaky fuel injector.
That fuel system is under pressure even when the engine is off, and injectors must close tight. I don't know how common it is to have leaky injectors in new engines.

it's not a single engine issue. all of these new generation honda turbo engines are hard on oil. I don't believe this is a design flaw. likely the way it is tuned

Seems like 5K miles is the max I'd be happy with.

I want a non turbo Honda engine.

A drop in fuel rail pressure will trigger a CEL. I've been down this road with Honda...

I think you are right, 5K would be the max. And yes, I feel like I should've picked up either Accord with manual or Civic but 2.0..

Isn't the fuel dilution coming from direct injection?

Oxidation number is typically normal for an amsoil.
Upgrade to xW30 and consider extending OCI beyond 5K-ish .

I've just noticed that oxidation number is abnormally high (at least comparing to what I've seen). Does anyone has any input on it?

I think there's another user here with a well documented level of fuel dilution in the same type of car. Blackstone readings of fuel might be bogus. Some have said you can't trust them lately for that. With a 5.98 cSt, I highly doubt there were "trace readings" of fuel. More like [censored] loads.

Oil Analyzers show >5% which sounds about right for this engine. I'd be going a 40 grade with that much dilution. I bet it would dilute down to a 20 grade after 4-5K.

I would just use Mobil 1 AFE 0W-20 and follow the MM. Bet your engine would last longer than anything else on your car.
