Oil change interval
I know this topic has been discussed before..
but..
I decided to drive the car until it told me to change the oil. I bought my car last July (2014) and have not changed the original oil yet...
Well this morning the change oil soon message finally came on for the first time...

I only put about 3000 miles on my car since I bought it last January. I changed the oil when I got it and reset the oil life reminder. A year later the message to change the oil came up. I am not sure if it calculates it on time or usage, but since it came up after only 3000 miles I would assume it just bases it on time, unless you drive a heck of a lot of miles and that becomes a factor.
For your car, how many miles did you put on it? Was it new when you got it? Did you ever check the oil life remaining when you purchased the car?

I bought the car brand new with 30 miles on it last july (about 9 months ago).
On my previous cars I used to get the tires rotated with every oil change. Looks like I need get them done separately as I feel 9k+ miles is to long to wait.

The oil life monitor uses an algorithm to determine when to change oil. It takes a wide range of factors into account. Things like mileage, engine temps, how often the engine sees high rpm, time, etc. My personal philosophy regarding oil changes has always been that too frequent changes will put a relatively small dent in your wallet, but too seldom will put a much bigger one. At least it will if you keep your cars for a long time.

I change mine every 5K and reset the Oil Life Monitor. I bought an extra air filter for my CAI, so I swap out the air filter with a freshly cleaned and oiled one I keep on the shelf.

I don't know if the oil life monitor is accurate, I was stuck on 68% for over 3 weeks even though I daily drive my car and put about 700 miles on it, but now it seems to be working again. I have put almost 4000 miles on my car since the last oil change and its reading 64% the last time I checked. I have just over 7000 miles on my car, I did the first oil change around 3,300 miles back in Sept 14. I'm probably going to do the next one in May.

I bought my 14 GT in August of 13 and my OLM was in the high 90's. The car was built in 02/13.
I changed the oil for the first time in March of 14 with 4,600 miles on it and the OLM at 43%.
I changed the oil for the second time in March of 15 with 6,600 miles on it and the OLM at 2% and the message center said to "change oil soon".
I would say that the OLM uses some of both time and mileage as well as the Algorithm.

There is no mention of mandatory oil change times in the manual that I know of. My car sits, unused from November to April, so I am not concerned about sludge build up. The oil I took out looked to be in good shape. I used the Ford semi-synthetic, as recommended in the manual. I just use good judgement for oil change intervals. I doubt the car can make a better decision for me.

Ah, I don't feel so bad now for going nearly a year without an oil change. Bought my GT in Aug of 13. Had the first oil change in May or June of 14 when it hit 5000 miles. It's only been 3000 miles later and the change oil soon light came on yesterday. I got it changed today. A couple of weeks ago my oil life was at 21%. Since my move last June, I only drive it once or twice a week.

But I drive mine year round. So I like to change it during the spring and fall anyway.

its not "mandatory" but there are guidelines of when they advise you change it, I've read it.
Summer time says that the average oil change should be done between 12-16k KM's.
winter time is 8 - 12k KM's.
my dealership "stresses" how imperative it is that I change it no later than 8,000KM's
So ... to be on the "safe" side, I change it every 10k
if I beat on the car (which we all do) I'll check the oil levels once I hit 8,000KM's and keep an eye on it to make sure that its at a healthy level or else, i'll make a service appointment.
