All,
Just changed oil at 10k and got the results back. All looks good to me except fuel in oil. Here's the results at 5k & 10k
Mi. on unit: 65,556
Mi. on oil: 4,908/10,011
Oil type: Rotella 5W40 (CJ4, not T6)
5k miles/ 10k miles
Cu: 2/4
Fe: 5/7
Cr: 0/0
Al: 0/1
Pb: 2/3
Sn: 0/0
Si: 4/4
Na: 1/2
K: 1/2
Mo: 50/49
Ni: 0/0
Ca: 1009/985
Mg: 1063/1013
Zn: 1259/1013
P: 1078/1012
soot: 0/0
oxi: 18/18
nit: 7/7
sul: 19/19
H20: N/N
glycol: N/N
fuel: N/Y
% fuel: NA/6.18
V100: 13.0/12.0
I found out recently that they don't report % fuel unless it's "high" or if you ask them to. The fuel might be from a bad injector, but I'm guessing it's just from running all winter with very light loads. I try to drive for good fuel economy, so the loads are always low.
Q) Since I didn't get % fuel reported at 5k, can you infer anything from the V100 to tell me if I had fuel in oil then? It would make me feel better if I did - less likely to be the injector if it's making oil at this slow of a rate.
FWIW, I recently got some fantastic fuel economy on a 100 mile trip (>29 mpg ~ 55 mph), and I wonder now if having a ligher oil could have played a role.
Trying to decide when to pull the next sample. Another at 5k, or sooner? Oil in it now is more of the same (last of my stash) Filters are M1.
