Amsoil Signature Series 0w-20 4k, Honda Pilot 3.5L, 4.5k

[rstcso]

Got back the UOA results after a 4k miles' trip. From right to left, VOA Amsoil SS 0w-20, UOA Honda OEM 0w-20 @500 miles, and UOA Amsoil 0w-20. Can see wear metals trending downward as expected. Based on the latest samples' properties, it looks like there may be some blending of the Amsoil and OEM oil that was left in the engine after draining and filter replacement. I'll send another sample of the used Amsoil currently in the engine after another 4k miles. Yes, Fuel Dilution: should be zero on the Amsoil VOA. Email sent to Lake to correct this and verify oxidation.

Thanks for the UOA, but there are some highly questionable changes from the VOA that make me suspect. Ca, P, Mg, and B all took more than a 30% loss to the VOA, but Zinc increased? The Moly result is understandable because of the factory fill remainders.... but I still have questions. Hopefully the next UOA will add some detail to this story. Overall, even if this report is 100% accurate, looks like everything is well so far!

14ppm of magnesium in Honda OEM oil? Is that normal?

Ca is very high so Mg not needed

Good points. I'll ask Lake.

Here is Lake's response to the fuel dilution in the VOA sample (mistake, for which he apologized). I also questioned why the molybdenum level from VOAs taken from the same source sent to multiple labs would differ between the lab Speediagnostix uses vs Blackstone and Oil Analyzers. He said the lab he uses utilizes RDE vs ICP. He doesn't say, but I'm assuming BS and OA use ICP?

"Thanks for catching the fuel dilution. Some the result from the 2nd sample got transferred into that cell. My apologies.

It is typical for it to take two complete oil changes to flush out the original oil, so the next sample should be closer to normal for the Amsoil.

In regards to the OEM Molybdenum level, that result is correct. The reason other labs show lower numbers is because they use different equipment to do the elemental analysis. Most labs use the ICP method, which only sees particles up to about 5 microns. We use the RDE method which can detect particles up to about 10 microns. Because of that, Molybdenum levels are different between the methods due to Molybdenum forming platelets of various sizes."

In the short time we’ve been seeing Speediagnostix voa’s and uoa’s here there seems to be a lot of inconsistencies/errors.

Your break in is progressing nicely! Look forward to future SS results.

I agree, and told Lake these discrepancies are being pointed out on this forum. I hope he starts paying closer attention.

It was good to better understand why his moly levels are being reported higher than BS and OA. I did some more research on ICP vs RDE and his explanation is spot on to what I read.

I’m sure it’s the lab but maybe double check before sending results to customers. It’s an extra time consuming step for them which stinks.
