2020 Ford Ranger 2.3 EcoBoost with high fuel dilution.
First UOA: Motorcraft blend 5w-30; 5.9k mi
Second UOA: Mobil 1 5w-30; 4.9k mi
Most recent UOA: PUP 5w-30; 4.0k mi

I bought in April 2023 with 14k. I use it as a my main work truck for my home improvement business so lots of short trips, idling, hauling heavy loads etc. Should I drop down to 3k oil changes based on fuel dilution?

I just put Amsoil signature 5w30 in it and was going to change it at 4k and see the results from there.

Also, I'm running premium 93 only and have the Ford Performance factory catch can installed since summer of 2024.

A few comments in no particular order:

- wear rates are perfectly fine, and in fact have settled to a very acceptable level; the engine itself if perfectly OK
- there's no distinction in the different lubes used; they are all in "normal" (statistically insignificant) bounds in terms of wear relative to macro data
- the contamination level of Si no problem; insolubles are normal
- fuel is not abhorrent and normal for an EB of this generation (though BS fuel values are vague at best; other services offer more accurate measurement)

Honestly, I see nothing here that would cause alarm. If you're going to commit to shorter OCIs, then use the least expensive lube you feel comfortable with. At 4k miles, even house brand lubes would be indistinguishable from these results.

The engine appears very healthy but the viscosity due to apparent fuel dilution I would find alarming. If it were my vehicle I would strongly consider jumping to a 5w40. With all the idle hours and fuel dilution this vehicle would also be a candidate for 3k OCIs.

The Pennzoil oils are also very thin for grade in 5w30, Valvoline EP HM is one example af an oil that carries the Ford spec but is blended thicker if you wanted to stay with 5w30. Euro 5w30s even a bit higher still but you lose the Ford spec approval, as you would with a 5w40.

BS Fuel dilution figures are inherently low so they've set their limit at 2%. Being that Ford recommends a 5w30 you can always jump to a 5w40 for piece of mind. Of course wear is absolutely fine.

Similar sentiment here. I'd not trust Blackstone's fuel dilution measurements to start with; not the best track record. I will be starting a UOA trend on a GTDI N22 engine and need a new UOA source for this very reason.

If mine, I'd run a Mobil 0/5-40 or Pennz 40wt and 5k OCI's.
 
You could possibly spend around the same money & go to a 0w-40 or 5w-40 and take it further to 5-7k then resample to see where it's at. That could buy you more time so you're not constantly changing oil so soon & running a business can be time consuming. As for the wear metals everything looks really good. Yes, it did shear from the fuel but that ending viscosity is fine for your 4k runs, in that Ranger, if you decide to stick with a 5w-30. Thanks for sharing.
 
Ya I agree with others. Your wear rates are good. The fuel in oil over time is what I would be concerned about. It doesn't appear to be causing any problems other than viscosity loss, which is not impacting wear.

Amsoil SS is going to give more solvency and could potentially keep your rings cleaner. I'd go 5k on SS. A less expensive consideration for you would be something like Mobil 1 ESP, which is highly shear stable or Valvoline Restore and Protect, which is not as shear stable but will keep pistons clean. Or, just stick with PUP as it seems to be working ok.

We overthink things here. 😜😜🤪
 
Thanks for the feedback everyone. I think I might try some 5w40 for the next change. I had a Saab 9-5 Aero 2.3 turbo that called for mobil 1 0w40/5w40 and it held up well in that motor when I tested it. I think I might have seen mobil 1 has a 5w40 turbo truck oil has well..
 
Is PUP one of the quicker 5W30s to shear down a grade? Almost every UOA of it I've seen shows it sheering down a grade even in vehicle that doesn't dilute fuel much at all.

Yes, the Turbo Truck is a CK-4 HDEO Mobil product. The Euro oil you mentioned should be work well & is easily found at WM or auto chains. Let us know how it goes if you resample.
