Fuel in oil question

[Rickfar]

I know this has been beaten to death, but I’m just trying to get some info. I have a 2019 Ranger it has 12,000 miles on it. I just got my latest oil sample results from Blackstone. It’s telling me I have fuel dilution of 2.5 I have always had dilution since day one. My question is has anyone had this problem and got it corrected and if so, what did they do to correct the issue?
Blackstone has said the viscosity of my oil is not correct probably because of the dilution of the oil with gas. I would just like to know if somebody has corrected this.
I gave the report to my local Ford dealer. He told me he was going to move it up the chain. I don’t have much faith in that, but I don’t really have no other choice..
Any suggestions would be appreciated.

Fuel dilution on the 2.3 Ecoboost is extremely common, and 2.5% isn’t catastrophic — but it is enough for Blackstone to flag viscosity issues. The first thing to understand is that the 2.3 is a direct-injected turbo engine, and DI motors naturally run higher fuel dilution than old port-injected designs because the fuel is sprayed directly into the chamber. That means more raw fuel contacts the cylinder walls during cold starts, short trips, and during enrichment events. If the truck isn’t routinely getting up to full temperature for long enough, that fuel never fully evaporates out of the oil.

The bad news is that Ford really can’t “fix” this because it isn’t a broken part — it’s a function of how the engine operates. The PCM commands richer mixtures during cold starts, during turbo cooling events, during catalyst warmup, and during short-trip cycles. If your driving style is lots of short trips or urban driving, fuel dilution will always show up in your oil analysis. Even brand-new trucks do it. You’ll see the exact same pattern on the 2.0, 2.3, and 2.7 Ford turbo DI engines.


There are only a few “corrections,” and none involve replacing hardware:

1. Longer drives that get the oil fully up to temp (20–30 minutes of continuous highway operation).
2. More frequent oil changes. Some owners drop to 3,000–4,000 miles.
3. Avoid long idling, which increases enrichment and reduces evaporation.
4. Use a high-quality oil that holds viscosity better under dilution
