In addition the change motor oil every 3K miles is a myth created by corporations with the intention of parting you from your money unnecessarily. - AfwN

I came here seeking info on just this topic. I was considering doing 3-5K oil changes, but wanted to see if the consensus was that that was really more frequent than needed on newer cars, which generally state that oil changes should be done at 5-10K intervals. So I have a follow-up question.

I just bought a 2013 Ford Fusion Hybrid (which I absolutely love, btw!), and the manual suggests changing the oil every 10K miles, for my driving, anyway. I drive 25 miles one way to work, most of it highway, at speeds generally between 40-70mph. A little stop-and-go along the way, but not too much, as I try to time my drive to avoid the heaviest traffic. I am also driving to maximize the use of the electric engine for better gas mileage, driving 60% of the way in EV mode. For those unfamiliar with the 2013 FFH, it can go up to 62mph in EV mode. I have frequently been able to go as fast as 63-64mph in EV for short periods of time, so it definitely lives up to that promise. I live in the L.A. basin of SoCal, so no severe weather, no road salts, etc. I will drive a few times a year out to the desert to visit my mom, but that's still going to be on a fairly well-maintained interstate, with rare wind-generated dust storms. I would likely change the oil much sooner after one of those.

Note that on the 2013 Fusion Hybrid, the electric and gas engines can sometimes both be running to maximize engine efficiency. As I understand it, most hybrids, especially prior to 2013 models, run in one or the other, but not both at the same time.

So my question: with a brand-new car, one that I intend to keep for 10 years or so, one that I intend to maintain religiously to get the most out of the car for the longest period of time possible: Is there any advantage whatsoever to changing the oil more frequently than 10K miles?

Also, on another board some time ago, mention was made that in that poster's car, using Mobil 1 oil had appeared to have a very beneficial effect on his engine (he's a car guy). Should I consider insisting on Mobil 1 oil for my oil changes?
