I have an '08 Acura MDX and a few days ago, I got this "A1 service due
soon" reminder and showing 15% oil life. I have more or less about
5,400mi/8,700KM on the odometer and this would be the first ever oil
change on our MDX. Normally, I think the first oil change for this
car's supposed to take place at around the 6,000mi/10,000KM or so, but
I could be wrong. The A1 service is just a simple oil change.

Now, normally, I think I'd wait until about 5% oil life remaining
before I went in for the very first oil change, but my wife and I are
leaving on a 3 1/2 week overseas trip in a few days and our car will
be left to sit in our garage during that time.

What I'm concerned about is whatever dirt, particles, sediments or
impurities that may have accumulated in the oil thus far with the oil
change coming up soon, perhaps some of that will be settling or
forming deposits in the engine from not driving the car for close to a
month.

Is this a legitimate concern? What would you guys do if you were in my
position? Just go in and get it done before we leave? Thanks for your
time and courtesy.

[FYI, many of you probably knew this already, but my car's manual
doesn't have a specifically set mileage intervals for the scheduled
maintenance schedule. I'm just supposed to follow the on-board
maintenance minder, which is supposed to tell me when and what type of
service I'll need.]
