Schaeffer's 15w40 2070mi. '03 6.0 PSD

[snoboy]

Ran this oil after draining out Amsoil 5w30 HDD due to abnormal sodium/potassium readings. Contamination occured when I installed my bypass filter and had disconnected the EGR coolant line while oil sending unit was removed and sloshed some coolant into the sending port.

This report confirmed that the coolant issue was not chronic.

Check out that 6.0 vis.

Short intervals like this are hard to judge.

The FE seems a little high with 4ppm/thousand. However, I expect that the ppm/thousand will drop with more mileage.

This oil should make 8k minimum.
