Below is a UOA I received after a 7200 mile run on Penz Gold 5w30. I bought the car used with 14k, likely a rental unit. I change the oil every 5k Since with Penz Platinum (except the last OC). Would you be concerned with the results of this UOA?

No. The only things that really worry me in an isolated UOA are the presence of coolant, fuel or perhaps a dismal TBN. Since that UOA didn't test for any of those items then there isn't much to say.

The wear metals aren't way out of whack for anything and since it is an isolated UOA then there's nothing to compare it against.

I this the Gold Semi syn dexos? I didn't like this oil, even in my snowblower.

I would try Pennzoil Bronze bottle HM, Or QSUD.

UOA doesn't tell much about wear. The wear "catastrophic" is in the filter pleats.

Did you look in the filter for timing chain debris?

What is the sound of the motor through warmup and drive?

i dont know the condition of the filters, but the only ones I use are Fram Ultras. As for the sound on start up there is a clicking from the high pressure fuel pump until warm (which was already replaced once) but other than that, no noticeable sounds.

The engine is too young. I wouldn't worry about it. I would have liked to know what the TBN was and if there was fuel dilution / coolant in the oil.

Try cutting back to a 6K oil change and then test again with TBN/TAN/Fuel Dilution/Coolant tests to be sure.

Fear 20wt oils if you want your engine to last. smirk2

TBN was 2.1 and there was a little fuel dilution, but they said it was not something to worry about.
