In my Hondas, I did not consider it an issue and went out to about 5k.
However, with the VW, I know from FF UOAs that, even early on, there was a lot of metal in the oil. So, I decided to change early and glad I did. At 1000 mi, the drain pan was full of glitter. I rinsed it out for a day with some Delo 30, and more glitter came out. Refilled with RP 15w-40 and run 3500 miles, still some glitter, about 1/4 of the FF.
