Honestly I am a little leery of a 10k interval nevermind 25k.




Many will tout the idea of UOA - Used oil analysis and generally it's a good idea.

That said - In a previous life I did a ton of M&R work with a major carrier here in the US. We'd run 75,000 miles on class 8 equipment before dropping oil. Filter changes at 25k. EGR motors that are abused quite a bit. If a UOA told me I was good to go, I'd not fret and roll with it.

Over the life of a car - oil isn't a super major expense so changing early for condition isn't the worst thing in the world.
