what is potassium in oil
Oil Analysis. High potassium and sodium in oil sample. The last 4 oil samples I've had ran have shown high Potassium (40-44) and high sodium levels (108-95) but no Glycol. I do have to add a gallon of anti-freeze every few weeks mainly do to a few cold leaks. The engine is a 07 Cat C-15 with 900,000 miles.
