...to a point. It also means the 'detergent' in the 'detergent oil' is doing it's job.
If you want to see clear oil when you drain start using non-detergent oil...if you can still find it.
Many moons ago there was an aftermarket Frantz oil filter. It's distribution was mostly just an early pyramid scheme. Just a stainless steel in-line cannister that held a press-fit roll of dual-ply toilet tissue...really. Their dealers almost always used non-detergent to show prospective buyers 'how clean the oil was'. Actually it worked well, theatrics aside. It was in line with the OEM filter and you could actually see metallic particulates residing on the end of the roll when removed for changing, particulates the OEM filters had passed. The TP also had the natural characteristic of absorbing water (mostly condensate) which the OEM filters wouldn't. This prevented a lot of corrosion and varnish build up, especially on short-trip vehicles.
A lot of long-haul trucking companies were using the five-stack versions.
I can remember when Mobile One synthetic first came out. The container said it was good for 25,000 miles. Unsubstantiated assertions from Detroit and oil producers brought that claim to a halt.

If you're are having your synthetic oil changed every 5,000 miles I would switch to non synthetic or a synthetic blend. 0ther wise you're not getting the benefit of going 10,000 miles between oil changes.
