PUP or VRP

Here's my 2016 Honda CR-V with the K24W 2.4 L gasoline engine, oil change history to date:

Build date 10 / 2015 so factory oil was put in sometime in that month.

1st oc 6,051 miles 2/14/2017 at Honda dealer, 478 days +/- 15 days & 6,051 miles on previous oil

2nd oc 11,599 miles 1/20/2018 at Honda dealer, 381 days & 5,548 miles on previous oil

3rd oc 15,726 miles 4/22/2019 at Honda dealer, 457 days & 4,127 miles on previous oil

4th oc 19,877 miles 2/15/2020 at Honda dealer, 299 days & 4,062 miles on previous oil. Note, I punched this vehicle 3 days later on 2/18/2020 with 19,877 miles on it.

5th oc 23,558 miles 10/21/2020 at Honda dealer ( free oc ) 250 days & 3,770 miles on previous oil

6th oc 27, 186 miles 8/27/2021 Note, I installed a Fumoto 90 degree angle drain valve, put in PUP 0W-20 & a Fram Ultra XG7317, 309 days and 3,628 miles on previous oil

7th oc 30,704 miles 6/11/22, 287 days and 3,518 miles on previous oil, put in PUP 0W-20 & a Fram Ultra

8th oc 34, 388 miles 3/21/2023, 283 days and 3,685 miles on previous oil, put in PUP 0W-20 & a Fram Ultra

9th oc 37,905 miles 12/8/23, 262 days and 3,516 miles on previous oil, put in PUP 0W-20, left Fram Ultra oil filter on for a second use because it was too cold outside to mess with it and Honda says its OK for two oc.

10th oc 41,451 miles 10/14/2024, 311 days and 3,546 miles on previous oil, put in PUP 0W-20 & a Fram Ultra

11th oc 44,635 miles 7/21/2025, 280 days & 3,184 miles on previous oil, put in PUP 0W-20 & a Fram Ultra

---------------

1st through 5th oc were all done at the same Honda dealer. So until 27,186 miles it got whatever the dealer used.

I have been changing the oil as soon as the oil life drops to 20 % remaining.

Note, at last oc, I had been using PUP 0W-20 for 17,449 miles, and before I started using PUP there was some yellow varnish on the dip-stick. When I checked the level after filling during this last change, I noticed that there is not any yellow varnish anywhere on the dip-stick now. The entire length is shinny silver steel.

I don't know how that translates into cleaning high temperature areas like piston rings, but it sure cleaned the dip stick after 17, 449 miles.

Lake farms out all of his testing, from what I been lead to understand. Not sure if that’s 100% or not; He does interpretations of the data. There are multiple videos on YT where he’s at HPL’s facility.
Yeah, the level of testing he has available for UOAs is very different from what HPL has in their lab.
