Toyota 5W30, 4k, 12 Jeep Wrangler 65K

[TXHunter]

Drained and filled with Amsoil ASL 5w30 at time of sample. We were about to pull a trailer to the beach with this and wanted to get a baseline sample before. We bought this used from a Toyota dealership, thus the Toyota brand oil in the Jeep.

Make/Model: Jeep Pentastar 3.6L v6

Blackstone comments:
Your Wrangler is wearing nicely at 65,283 miles. Most of the wear metals, especially iron and copper are lower than universal averages, which show typical wear levels for this type of engine after about 6K miles on the oil. This was a shorter run, so some lower wear is expected, but iron and copper are still lower on a per mile basis so the steel and brass/bronze parts are in very good shape. The Toyota oil did a fine job and it'll be interesting to see how the Amsoil compares. Air and oil filtration are working well. Try 6K miles on the next oil.

Looks pretty good, be interesting to see the difference if any.

Since the Pentastar is easy on oil and you're using SS, I'd change Blackstone's recommendation to 10k miles - and only take a sample at that distance. No sense running SS only 5000 miles, especially in the 3.6.

What filter do you plan to use?

No reason not to use Amsoil SS for less than 12K. You will not gain anything.

I went with a Wix 57526 filter for the first oil change.
