C-12 Cat, 430 hp, Kenworth road tractor.
Rotella T 15W40 (dino), 10 gallon sump, 2 1/2 gallons make up oil during interval. 35,000 (thirty-five thousand) miles on change.
These numbers are very good, and it appears to me that the oil held up incredibly well. Probably could have kept running it.
Sb Titanium Silver Cu 54
Pb 11
Tin Al 11
Ni 1
Fe 80
Chromium 4
Cd Na 8
Boron 1
Si 12
Water %soot Glycol Negative
Fuel
Viscosity 15.69 cst @ 100 C {still a heavy 40}
Additive package:
Zinc 1477
Phos 1331
Barium Calcium 4106
Magnesium 16
Moly
This wasn't an experiment with a twenty five thousand dollar engine. It was an OVERSIGHT that this oil wasn't changed at the usual 25K OCI's we've been getting. But it certainly looks like no harm was done.
