M1 0W-20, 2002 Honda Odyssey engine, High Copper

[btanchors]

I just got this report back on my 2002 Honda Odyssey. This is the very first UOA I have done on this vehicle's engine. See a separate post I will be making regarding an abnormal transmission UOA. Meanwhile, here is the info, from Analysts, Inc.:

Vehicle has Honda's 3.5liter 240HP V6. Engine had 29,941 miles on it when the sample was taken. The engine oil was Mobil 1 0W-20, using the Mobil 1 M1-104 filter. The oil had 4,875 miles on it.

Iron: 14
Chromium: 2
Nickel: Aluminum: 4
Lead: 2
Copper: 32 Underlined as significant
Tin: Silver: Titanium: < 1
Silicon: 8
Boron: 169
Sodium: 10
Potassium: Molybdenum: 69
Phosphorus: 958
Zinc: 1118
Calcium: 3190
Barium: Magnesium: 31
Antimony: Vanadium:
Oil added: 0.5 quarts, sump capacity ~5.5 quarts
Fuel % Vol: Water % Vol: VIS CS 100 degrees C: 9.8
SAE Grade: 30
Glycol Test: Negative
TBN C D2896: 6.83

At first, I was alarmed by the high copper, but through searching other posts in this forum, I notice that other recent vintage Honda 3.5 V6's also tend to have high copper...I wonder what is causing this? Other than the copper, I think this is an excellent report. Also of interest is that the Viscosity is reported as SAE 30 instead of SAE 20 - Is the Mobil 1 0W-20 already close to a 30 weight at that temperature? The TBN suggests the oil is fine, so I don't think it is thickening due to oxidation....

The note on the report says that the values are noted for monitoring purposes only. In other words, the report is not marked abnormal, but the values bear watching. It says to Resample at the next scheduled interval. I changed the oil and filter anyway....

It could be just a quirk for that engine. Key is-is it coming down. Everything else looks good though. I'd say the thickening might be a mistake.

High copper is normal for these Honda/Acura V-6's and the rest of the wear rates are fine.

You could go to a 6000 mile drain interval, based on these results. I generally use a lower limit of 4.0 on TBN with the ASTM D-2896 test method....

I believe the 0w-20 starts out at 9.0 Cst, so it's thickened a very small amount, which is normal for a shear stable formulation.

Since the copper didn't come paired with high tin or lead I wouldn't be at all worried about it. Probably from an oil cooler or some such. I don't believe there are any load bearing surfaces in the engine made up of pure copper. If there are any bushings used to carry a load they are generally bronze, which is a copper-tin alloy.

No worries!

This is a nice report for this engine.

Agree, this is a fine report.

Is this the actual Honda engine or is it the Isuzu engine that Honda subbed out? Copper is common with the Honda engines.

This motor should be the same as Honda Pilot/Acura MDX. Are you sure that the sump holds that much? The capacity spec from Acura is only 4.2 qts. From experiences on the MDX, 5 qts will be past the add mark on the dipstick(dealer changed the oil but I provided the oil in qts) and my recent 2 oil changes resulted in less than 5 qts fill by 400ml & 200ml(with 15400-PCX-004 oversized filter) respectively.

Ditto for no worries on this report. How long was the OCI?
