What oil brand is everyone using
I have been using pennzoil ultra premium 0-40
Srt filter. I’m wondering about the fuel dilution and definitely worried about the copper.
Does anyone else have oil analysis that I could compare with. Does anyone also have any recommendations on why copper would be higher and should I worry about it

Hey mikek1971 -

If you use the Search feature and search "Oil Analysis", you'll find a bunch of member commentary in various threads that'll give you some analytics and likely answer your questions.

Pennzoil PUP 10W40 for mine.

A couple of threads with 392 oil analysis:



Based on Blackstone's averages for the 6.4 Hemi, your copper number seems reasonable and is much less than the other two listed tests. Wonder if the comment from your lab is based on an average engine or specific to the hemi?

Fuel dilution - Any clues based on your driving use case - cold outdoor temperatures + short trips vs extended time at full operating temperature?

I seem to recall copper should fall 10-20 ppm. Some motors will be higher, some lower. I don’t know what’s normal for the 392.
Fuel dilution, 2-3% is normal range. A bit higher for diesel.
 
Thank you all
I’m trying to research and see other top of the line oil to use also.
By the comment they said it just has me even more confused and worried.
It’s a daily driver 26 miles one way to work. Had a week or 2 where temps were below freezing and a few days around 0. Garage kept except for during the day

I’ve talked to Mobil, they do not have an oil that meets the specs for our engines. They specifically told me that their European formula doesn’t have the proper additives for the Hemi.
 
I change my oil every 5k along with a 5-tire rotation. Mopar Recommended Pennzoil Ultra Platinum Full Synthetic 0W40 Motor Oil, API Approved, Specifically recommended for all SRT Engines (392 Hemi, 707 & 840) (FULL SYNTHETIC) & Mopar oil filter part number 5038041AA high capacity oil filter upgrade.
