UOA- Amsoil 10k mi, bypass

What do you guys think of the copper.

Re: UOA- Amsoil 10k mi, bypass

Copper is elevated. 20 is kinda high but still within the normal limits. I will post the chart for the wear metal limits/values on a diesel engine. The number that has me more concerned is the oxidation level. Your report says 37.

Oil oxidation is a direct measurement of an oils serviveability. This can creat acids that can cause corrosion increase viscosity and deplete additives. Nitration levels are considered normal under 50, but ussually seen in the single digits unless high extended drain intervals are used. I will bet $20 that you will go over 50 if you run the oil another 5K like recommended on the UOA.

The viscosity (VIS) is getting close to a 30 weight oil. When the CST 100*C drops to 12.5 it is a 30 weight. Currently yours is a t 12.9. Not uncommon for amsoil in a Powerstroke.

Which bypass filter are you using?

Here is a report for comparison:



Here is a chart that explains in more detail the different items and values found on a UOA report.

Thanks White buffalo.

I have 3k more miles now, Maybe I'll change it and send another sample to see.

Re: UOA- Amsoil 10k mi, bypass

I would change it just for the reasons of the viscosity dropping down close to a 30 weight oil and the oxidation levels.

Your wear numbers are all within normal limits, especially considering 10K on the oil.

10K is a good extended oil drain interval run for that oil.

I'v read some of your other post relating to different oils.
We started using Amsoil over 25 years ago. 1st tried it in a 8v-92 in a boat. EGT dropped at WOT from 780-720, and wtr temp185-182. That was against delo 400. Looking at your experiences, looks to me alot has changed with oil over 25 years. Noticed Shaeffer's is popular. I may try that and compare.
Thanks for the info.

Re: UOA- Amsoil 10k mi, bypass

Well I don't want to come across as an Amsoil basher. I used Amsoil in alot of my other vehicles ('98 Harley-Davidson, gas pick-ups, cars, etc) and it worked very well.

But with the 7.3L PSD it just did not perform better or as as well as some of the other options out here. Along with the high price tag of $33 per gallon it was quickly turning into a $150 oil change. If I'm paying that much more for oil I would expect better UOA results, i.e. lower wear metal #'s, better viscosity longevity, etc.

Schaeffer's cost almost 1/2 the amount at $17 per gallon with excellent UOA results.
