N14 oil analysis

[dane333]

I've just done oil analysis on 2000 volvo vn 420 cummins 460hp and this is what i've got.I don't know anything about this so if someone could help me I would appreciate it.Keep in mind;this truck was sitting for about 5 months.

aluminum 13,chromium 5, copper 3, iron 40, lead 5, tin 3, silicon 21, potassium 5, sodium 45 A, moly
In the report it also says;
*All engine wear rates normal. Sodium level (oil additive/coolant) higher than typical. Chech for source of coolant leak. Drain oil and change filter if not already done. Resample at next service interval to monitor. Truck has 1, 100, 000km or 660,000miles.

If anyone can explain analysis to me I would greately appreciate it.
Thanks

Usually potassium would be higher along with sodium also indicating coolant. Aluminum is kind of high in my opinion indicating piston wear. How many miles are on this change? I would just see what happens on the next oil change since it's not really affecting wear. Silicon seemed kind of high. Both silicon sodium, potassium stay around 5ppm on my engine. 6.7 cummins. I know it's smaller than your 14 liter but it gives you something to go off of. Aluminum is usually around 2 or 3 ppm on my engine.
I wouldn't worry yet. Just see what happens next time. The sodium is also an additive in some oils. I would maybe check the air filter to see how it looks since silicon is kind of high.

It says Glycol not detected, but they say to look for a coolant leak. Wouldn't they detect Glycol if there was? What oil did you use? What miles on the oil at time of analysis? What kind of driving you doing mostly ie. farm, city, highway (I assume w/ that mileage)?

Doesn't look too bad. But a little more info necessary.

That is a fine UOA under those conditions.
