I'd like to get some data points such as any material, description of the material, as well as the vehicles mileage and oil change interval to gauge what is normal. Please follow my format:
2020 P400
51K miles
northeast (not used to tow)
oil changes every 15-17.5k
very occasional light silver specs(fine shavings) and some red material (maybe gasketing or chain guides.

If you have any suggestions, let me know. Would like to gauge what's normal wear.

 

2021 P400
45K miles
Northeast
Oil changed every 7,500 miles
Just black oil residue on the filter. Never saw any silver specs.

2025 P400
26K miles
Northeast
Oil changed every 10,000 miles
Just black oil residue on the filter. Never saw any silver specs.

 

2020 P300
72K miles
Northeast and Southeast U.S. (some towing, some off-roading)
Oil changed every 5,000 miles (using Liqui-Moly meeting JLR spec.)
Just black oil residue on the filter. Never saw any silver specs nor any red material.

 

Go to Waldo's World YT channel and watch his 6-video playlist on a Range Rover he worked on, it's fascinating and he goes through this oil thing as well. Different vehicle than yours but all those videos kept my attention - I played them at 1.5x speed.

 

If your really interested whats up with your oil send a sample to Blackstone Labs. If you reach out to them theyll send you a sample pack for you to send back to them, theyll send results back with an actual analysis on your sample.

 

2022 P300
88,000 miles
Upstate NY (lots of Towing and lots of heavy Off-Roading)
Oil Changes: since new at 1,000 miles, 2,000 miles, then every 5,000 miles after
OEM Oil (0W-20) and OEM Filter every time
Just black oil residue on filter, no silver specs ever
All oil changes done by myself through the drain pug (never vacuumed the oil out through the dipstick).
OEM Magnetic Drain Plug: Has always been clean
