This oil was sucked out of family member's car piping hot after a 170 mile roundtrip. I expected that to make the flashpoint and fuel % better, and it did. It really makes me wonder sometimes when we see low viscosity and low flashpoint if it could be from fuel temporarily being in the oil that would have later gotten burned off and returned to normal? The last time I did this sample for them it was only driven 5 miles around city streets to warm it up and Flashpoint was much lower with a trace of fuel. Makes me think the immediate driving before the sample is a big indicator on those readings?
This car had a lot of city driving during the 5,700mi and one year. They didn't have me run an analysis on this one in over two years, and I don't think they need to next year either. It looks good (knock on wood). It does have some solenoids and sensors slightly leaking on the front of engine, but they are fairly easy 75 cent O Rings to replace, and it makes no difference on the dipstick yet. The report is rather boring (good thing).

(Note - the viscosity was essentially identical to this Mobil 1 0w-40 I tested a couple years back with only 189 miles on the oil! It must shear SLIGHTLY immediately in this engine, but then stay right there both SUS & cSt were virtually identical when it had only 189 miles on the oil).
