Schwaben Scan Tool
I will compare my S-Scan tool to my OBDLINK MX this weekend. I am betting all our N55's fall within a range (stock engines) and the variations that we are seeing are based on how and where we are reading the oil temps & or even confusion over coolant temps.
.
Regardless the oil temps are what I consider high (above 240) where the concern starts and raises an eyebrow as to the oil spec / viscosity and OCI.
