Blackstone Oil Analysis Report(s) | Hybrid

[The Real Maverick]

Regarding flashpoint IN GENERAL.

NOT SPECIFIC TO ANY ENGINE OR BRAND OF OIL:

Flashpoint of 300°F (150°C) or higher is considered suitable.

Some will want to argue "suitable" is a long way from "ideal". Ok fine. Please don't argue.

I feel 365-370°F is a long way above "suitable".

To me, it shows that even a 12k OCI is still remarkably conservative for your use case.

And more importantly - you have a happy little 2.5L.

Should be over 385 Blackstone spec
Ford oil spec at new at 425F.

and yet my Ford oil was at 450*

This is well beyond splitting hairs.

450 is over the 425 spec. 100% no argument here

Well did ya use 50 weight?

Better check!

450 seems unreasonably high.
Blackstone says the average for used oil in gasoline engines is 380 and 410 for diesel engines.

Water in the oil, or some additive you added are the ways flashpoint can go up.

May be a typo? Yours was higher than virgin oil?

This was Motorcraft Full Synthetic 0w-20. No additives.

Blackstone will also tell you that the flashpoint test itself is more of an indicator rather than something that can be valued in a vacuum.

I think it’s also worth noting that the specs listed are their minimum acceptable specs. There will be some variation.

450 sounds like an outlier.
How can you account for it?

It does, in general, move upward with heavier oil stock.
