M1 HM 10W30, 5,100 miles, Volvo 240 B230F

[Sam_Julier]

First UOA on my 1993 Volvo 240 with the B230F engine. JG Lubricants says sodium at "high range of normal, continue to monitor". Not sure what to make of this as there is no coolant loss. Clearly the oil could have stayed in longer.

What was the last full of oil? If it was Peak, Valvoline or a oil that uses Sodium; that's a possible cause

I honestly don't know then my friend. There isn't much potassium in the sample I see

Great engine. My 1990 240 DL wagon is approaching 350K, and it still runs great. Keep the flame trap clean!
