while your tbn may be a good value, your flash/fuel shows your oil is not really in that great a condition
imho i would not go 40hours on an oci and i would switch to SRT as well
Fuel contamination might be because I had a cold start and only ran it for 15 minutes before changing the oil and taking the sample. This unit is carbed, not FI. That said, it seems all of my engines in any application have low flashpoints and excess fuel, except my 17 Ford Escape which is known for higher unburned fuel. Go figure.
