Amsoil Signature 0W20 8k Miles 2021 Jeep Gladiator

[Nuclear_42]

Here’s my second report. The report does show my previous sample as a comparison so it’s a little confusing to analyze. My fuel dilution has disappeared either my rings have fully seated or stopping my habits of long warm up idles in Minnesota winter or both. Overall I’m happy with this oil and may push 12k before changing this oil out.

I would go 10,000 until the iron drops to under 50ppm. Thats just me...

Are those Fe levels within normal range for this engine? Everything else looks good.

That’s pretty high compared to wwilsons two 3.6 Pentastars

10 K would be fine….

iron, silicon, copper, all appear to be trending down this sample. So, we'll chalk it up to potential break-in wear for now. I really like those gladiators!

Very nice report

Both samples are from the same oil, right? It's interesting how driving 1180 miles increased the viscosity and eliminated the fuel dilution, without changing the oil. I guess when each sample was taken might matter (hot, cold, after long drive, after idling).

Copper is normal but this iron is high for the mileage.

Same oil brand but two different runs.

Could the iron be high due to cold starts in extreme Minnesota winters?

It's also still a pretty new engine.

It's still wearing in, but I don't think there's a need to be concerned at this point. Engine break-in isn't a switch flip.

Interesting to see the formulation changes run-to-run, I assume these were two separate batches?

What racer12306 said IMO. Hard to say based on limited data. Next sample will hopefully help.

Here is a 3.6 with 62k with an Fe reading of 11ppm after 4,500 miles during winter.

Ah. I was thrown off by the NO in the Lube Change column.

I have to assume the differences in levels are lab error, which are noticeably fuzzy on soft metals and P

Could be, it looks like the 2nd batch had more ZDDP, that's why I mentioned it.

I'm sure there will always be a delta batch, then even larger lab error, 50-60 ppm is within reason for a $30 UOA

Looks ok, but, I would go shorter ocis until it's broken in. I would prefer to get the break in metals outta there more quickly.

It’s interesting they list the 3.6 as direct injection on the report, it’s definitely not lol
