[wussyPup]

1HD-T from 1990 HDJ81 with 136,700 Km.
Finning analysis of sample of Esso XD3 0w40 with 4,700 Km.

Action Required

ABNORMAL SODIUM CAN BE RESIDUALS OF COMBUSTED COOLANT ENTRY THROUGH CYLINDER(S),
OR ADDITIVE, MISC. SOURCES; GLYCOL TEST IS NEGATIVE. OTHER ANALYSIS READINGS
APPEAR TO BE ACCEPTABLE. SUGGEST TO CHECK OPERATION TEMPERATURES, VISUAL
INDICATORS, COOLANT LEVEL, CONDENSATE, ETC. SUGGEST TO RESAMPLE @ 4500 KMS. TO
CONFIRM & MONITOR. EVALUATION CAN BE RE-ASSESSED WHEN SAMPLING HAS FURTHER
DEVELOPED A TREND FOR HISTORIC COMPARISON.

Could the high levels of Sodium be leftovers from the higher detergent oil used in Japan?

THe analysis doesn't say 'high' levels of sodium rather it says 'abnormal' which begs the question; What is normal?

Considering the numbers for Calcium and Magnesium, I don't find the results surprising.

hey Steve, i just got my second analysis done, and i got high levels of silicon as well, is there something to worry about?

Silicon is dirt. Check your air cleaner and pipes.
