You will be fine...change the oil before you go, then check it regularly until you get back.
Data points from my personal experience to add weight to my recommendation.
New Colorado has 15,000km service intervals, and an OLM
* bought it as a demonstrator with 4,600km on the clock, and 62% of the oil life consumed. I'm now at 8,000+km, and only down to 76% consumed...one 900km round trip in 26 hours, and it didn't drop 1%....idle bad, highways good.
* Holden (GM) state that the OLM on "ideal" (read highway) conditions can exceed the service interval, change annually.
* They also state that you should change within 1,000km of "0%"...there's a safety factor.
Mobil, back when I had a 1990 4Runner, and after pushing the point that Warranty was long gone suggested that annual changes with M1 0W-40 were fine...whether you did 5,000km in that year, or 35,000km....again idle bad, highway good.
