Yep. Do this also. Also post in the new oil filters, tools, VOA, UOA, and other threads. Extra documentation if needed. That's probably part of why I
Donate to BITOG, as I consider the donation as a partial storage fee for my documentation, besides this forum being the best I've ever been part of since starting out using 1200 baud modems.
The last OCI, when I switched from using Amsoil Signature Series to HPL Premium Plus Passenger Car Oil, I even shot
a short video of doing a flush with a new quart of HPL after draining the Amsoil and before putting the drain plug back on (new crush washer) and adding the HPL, and posted it to YouTube. No talking, but the description has the documentation. The video is completely boring, unless you like to see a quart of HPL being wasted (almost).
I keep my documents separate from my vehicle so they don't "accidentally" get "lost" should I need any further service done at the dealership. I even print out the PDSs for the oils to show the specs they are certified and/or meets or exceeds.
