Very high fuel/coolant numbers on my Blackstone Oil report at 20k.

[Swede726]

Going to test again at 25k to see if they improve..

2020 SuperCab purchased in April 2023 with 14k on it....

Fuel and coolant seem way to high?

Is this your first oil change since purchasing it?

Sample back again would be the best suggestion, maybe Change the oil and coolant again is what I would do, maybe bring it up to see if the dealer is willing to work with you (some simply tell you to pound sand if you bring up a oil analysis concern)

Doesn’t take long to get fuel dilution, especially in winter. It’s way less with a catch can.

3% fuel isn't anything to worry about IMHO, and numbers are always higher in the winter.

Go enter your results in the long running poll.

I've had 8 back to back Blackstone tests and I see averages and trends. Fuel in gas is always higher in winter for me. In fact in that poll above I figured out my average, went back and just put that in.

Interesting

Yes do another cycle and see what the new report says

Interesting your TBN is high, oil still had a lot of life left in it

You have 30PPM of Potassium and 7PPM of sodium which from my experience indicates that you are leaking coolant into the oil. I would sample again in 1K miles and again 1K after that (without changing the oil) and see if the potassium is still rising.

This is one of the primary values of a UOA to be able to detect a coolant leak long before traditional method will.

The engine runs rich warming up in the winter. Short trips contribute to high fuel percentages in the oil. The 2% standard was determined before direct injection engines so it might be a little low to be the standard now. You might get a better report on a sample taken after driving in the summer.

It's a little early to be concerned.

Check out my oil samples. My potassium and sodium went down as the miles went up.

Might as well have your transmission fluid tested as long as you're looking for bad news...

It was a CPO and the oil was changed at 14k when I got it from the dealer.

Not too worried about the transmission as the truck has an extended power train warranty to 100k as it was gold certified cpo by Ford. Its a work truck so only plan on driving it for around 5 years.

Just installed the ford performance catch can and will see if it helps on the next report.

It won’t, the FO catch can only draws off the top of the valve cover on the non suction side of the PCV system. It may catch some but not like the raw fuel you would catch with a better system.

Why fix what isn’t broke?
