Valvoline R&P 5w-30 5k mi; 2001 Crown Victoria 149.4k mi

[GriffinB]

This report is from my 2001 Ford Crown Vic with 149k miles on it, everything is stock and it is used as a highway commuter, so pretty light driving, occasional WOT, but I don't necessarily drive it like a grandpa. Oil filter was a Champ Labs PH820XL, I will post a C&P after this of it. OCI was from 4/4/25-7/15/25, 5,161 miles, I had to add 1qt at 3,000 miles. Ambient temperatures have been very hot, mid 90s, very humid and lots of rain, A/C running for longer periods, I am in South Georgia.

The next oil I put in it was SuperTech 5w30 FS HM, I am going to do a UOA on that to see how it looks, particurally the wear metals compared to this R&P. Then maybe I'll do some ST 5w20 and see how that looks. I also put a Pronto/PG filter on this time.

Why did you only use R&P one time?

This was my second time using it on this car. But it was not needed, engine is extremely clean and looking through the oil fill port the top of the heads are still practically grey. I just ran it to do a little cleaning and see what it would do.

The only concern would be the Al the first run, but it came down. I would have expected Fe to be elevated based on the filter. What is the history with oil pumps on this engine?

I agree the Al is worrying, it went down but could've just been a fluke. Weather was also considerably warmer this time so cold starts would be easier on the engine I assume. Especially because the macroanalysis posted by BITOG uses the Ford 4.6L and the avg was only 3.3ppm for Al, Fe and Cu is lower then avg so that's good.

From what I've heard 4.6s have extremely low oil pump failures, as far as my engine specifically nothing has been touched on it, everything is stock and original.
