FL5 engine oil dilution

[EJBFL52023]

I'm not a mechanic but I have had numerous Honda's for over 35 years. In addition to the 2023 Type R with 22k on it I purchased new, I also own a 2018 Honda CRV. The Earth Dreams engine in the CRV has a known oil dilution issue. My non-mechanic experience is that clearly smelled fuel in the oil of CRV with it's oil dilution problem. I've not smelled that in the Type R despite the appearance of clear "thin" oil on dipstick. I always do the oil change at Honda dealer using their 0W20 oil. My guess is if you aren't smelling fuel in oil you're car is fine even though it appears clear and thin. I waited until maintenance minder indicated oil change was due last time and although a bit dirty in appearance the oil was still not showing that thick dark black color nor smelling if fuel.

Hope this helps.

Attached is my latest Blackstone analysis. As I stated they use flashpoint to determine fuel contamination. The flashpoint in my sample was above the minimum temp that it should be so they say the sample is not suffering from major fuel dilution.

Nice results I'll be switching to liquimoly 5W30 in my next oil change in about 2 weeks, I live in South Florida and the stop and go traffic is insane even worse with 80°+ degrees ambient temp plus humidity, I'll be sending a sample to Blackstone as well with my current oil 5W20.

I just switched to HPL Premium Plus 0w-30.

I used Blackstone. They'll send you the test kit for free, and then you pay when they do the test.

Ordered my kit but, this is what it looks like at 4,930 miles. I did the recall today too. My buddy who's the dealers master mechanic did the recall fix and the oil change in about 40 minutes.

I mostly travel to work on the highway but, I live in a city so short trips happen as well, and my guess would be that's what's doing it is the short trips. I let it warm up for about a minute, drive easy until she warms up, I'll see what blackstone says eventually. I just ordered their kit. I should've ordered it when you said something.

Seriously though, you can't judge the oil based on how it looks or smells, unless it's gummed up or something. I've heard before that you should be worried more if the oil is super clean looking because then it may not be clearing out all the junk from the engine.

I did read that the oil being dark brown or black can mean it's still doing its job. That's what I'm thinking. I'll see what blackstone says but, yeah it was getting a little dark for my liking at the same time. I usually change mine around 5k though on my vehicles and always use full synthetic and a good filter as well. I have two more free oil changes from Honda then I'll be doing my own at that point.
