Third use of the Amsoil Signature 5W-30 + MolySlip combination with Amsoil EaO11 oil filter, about 10,000 miles per oil change, changed annually. With the Amsoil filter, 5 quarts of Amsoil + 10 oz of MolySlip was right at the full mark on the dipstick (not overfull).
This is the first analysis done. The truck had about 124,000 miles when the sample was taken at the oil change. I mailed the sample on 5 May and the report arrived in my e-mail yesterday.
The truck is not losing any coolant. See what you think of the comment about sodium.
