Old habit. I used to do that when I was pushing 8k and 10k OCI’s back when the car had less than 200,000 miles. I would replace the oil filter at 5k and top it off with the ~1 quart of fresh oil. Just wanted to keep TBN and add-pack fresh during the course of a long OCI. Always felt that a $5-$6 quart of fresh oil would safely get me to the end. I usually don’t do that on a 4k-5k OCI. But in this trial I’m doing, I went ahead and did it at 3k on the first 5k run and at 4k on the 7k run (but keeping oil filter in place not replacing). I’m gonna do that at 4k on my current 8k run and stay consistent in my methodology. Just a cheap insurance preference I like to do.

Cousin's 03 2.4 usually consumed 1 qt every 2000-2500 miles. Tried multiple brands with the same outcome.
First run of Valvoline R&P 0W-20 and it is barely 1/2 qt low after 3K.
Have you owned this 2008 Honda Accord since new? If not, at what mileage did you buy it? What has been your oil change interval since you owned it, and have you been using synthetic, synthetic blend, or conventional oil? Sorry for so many questiions, just trying to learn your secret to going 352,000 miles on an Accord.
I am original owner. Bought it new. Broke it in on conventional Valvoline oil within first 1,000 miles. I think it was around 600 miles or so on first oil change. Then at 1,500 miles. Then at 3,000 miles. Then at 5k miles. Then at 10k. Got into a cadence of 5k OCI’s using Mobil1. Then switched to Valvoline Synpower synthetic for a long time. Then started trying Amsoil and 10k mile OCI’s. Did that for 40-50,000 miles. Then switched back n forth between Valvoline and Pennzoil Ultra Plat a few times… and going 10k intervals with an oil filter change at midway mark of 5k and topping off with 1 qt of oil. Once I began the Honda start up rattle, then replaced the actuator and timing chain, I went back to 5k intervals. Been doing that since. Again switching up oils between Amsoil, Valvoline, and Mobil1. I finished with Mobil1 Ext Perf HM oil before switching to Valvoline Restore & Protect. Oil consumption reduced from 2 qts per 5k to now 1/2 qt per 5k. It’s was burning those 2 quarts per 5k for over 100k miles or more. Even before the timing chain replacement at 220,000 miles.
I’m done with switching oils now as VR&P has delivered sig less oil consumption and fantastic wear oil analysis.

I do that with EC30 to offset dilution and boost the oil …
(Mono grade should do that well) …
5 mins with a Fumoto valve - a bit longer if it’s an oil filter …
I've likewise had some fantastic results with VRP based only on cleaning in my 212k miles 05 Odyssey. No UOA on it, but with wear metals so low in this K24, it makes me wonder if there's any point in using HPL in my J35 or my newer K20C4. Can this wear rate realistically be improved upon? It seems to me that it really cannot be, at least when you are doing easy highway miles. Maybe in a different duty cycle with more cold starts some other oil would show a better wear metal performance at these miles.
But dang, how much better realistically can things get?
Not since 220,000 mile mark. Replaced timing chain and tensioners. Otherwise, nothing done to the engine. Transmission is also original and has had Zero work done to it other than fluid changes.
