Default A question revisited; when should I get my first oil change?

I've got just over 3000 miles on my new Mustang GT (I guess it's not new anymore!). I asked before about when to get my first oil change, and it was suggested I read my owner's manual.

The owner's manual states for the first oil change to be done at 10,000 miles. My oil life monitor says I have 73% oil life left.

10,000 miles seems like a long way to go without an oil change! Do these cars ship with synthetic in them? At what intervals are you guys doing your oil changes? Synthetic?

I just did mine when the monitor said 10% oil life left. I'm pretty sure the GT ships with synthetic, but I don't know if it's the Motorcraft full synthetic or the Motorcraft blend.

I know 10k seems like a long time, but modern engines are built a lot tighter, the surface finishes are better when the thing is assembled, and fuel delivery is a lot more precise. There isn't as much to contaminate the oil as there used to be on older engines.

it won't do any harm to change it sooner, mind, but I think people tend to fall for the "tiger repelling rock" fallacy when they advocate much more frequent changes. But it's your money, if it gives you peace of mind go for it.

I have a 2014 GT (1,300 miles), and my understanding is your first oil change should not take place before 5,000 miles. I'll probably change mine for the first time around7,500.

I also believe your GT is delivered with a synthetic blend.

Ford Motorcraft also sells an oil cooler ($400-$500 cooler, hoses, etc., installed) that you might consider for your Georgia Summer. Lowers your oil temp about 30 degrees. There's a recent thread on that. Arguably, there is nothing better you can do for your engine's life along with proper and timely oil changes.

I have the 5.0 in my 2013 F150, first oil scheduled change was 5,000 miles. Our local Ford service center said to wait until it was due, as it helps the engine break in properly. I have heard stories about people changing to synthetic when the engine is brand new and not having the rings seat properly. Most Mfgs will not consider a car that uses a qt of oil per 1,500 miles a warranty issue. The way I look at it is, first change go by the book, after that change it early if it makes you feel better.

n.b. do check the oil level occasionally, though. both Mustangs I've had (2010 and 2012 GT) consumed one quart of oil before the first change, and none thereafter.

The cars have a synthetic blend in them. Change the oil after 5,000 miles, but probably best to do it when the computer tells you for the first change. I personally don't wait until the car oil life reads 0%, but I feel comfortable changing the oil at around 7,500 miles.

Thanks for the replies guys! I think I'll hold off to around 20% to 10% oil life left before I get an oil change. I'm also considering an oil separator: http://www.americanmuscle.com/black-...ss-1114gt.html
I've heard these keep a lot of crud out of the motor. What's the consensus on these?

Oil separator is a must have! I cannot believe how much oil blow by mine catches. Definitely buy the first one for the passenger side if you are only buying one. Also, do some research. There are some comparisons, and UPR oil separators/catch cans seem to perform best.

The book may say 10,000 but the warranty service is 7500.

Just took the 13 in for the first oil change and it said right on the paperwork:
"To keep your warranty service in good standing, oil must be changed before 7500 miles"
it was at 7604 when it went in

If you don't like what Ford recommends, then do it whenever you feel it needs it. This is not an exact science here. If you drive your car hard then you should change sooner.


Very simple.

GLOCKer, your 2014 Mustang GT comes with synthetic blend from the factory. I changed mine before the 1000 mile mark. I have always done this with a new engine. I changed my oil at the 5000 mile mark, then will change it again at around 10,000 miles. I live in Florida, where the temperatures reach 95 daily. Consider that, plus the heat from the asphalt, idling with the A/C on in traffic, and taking the engine up to redline every so often. Changing oil more frequently than every 10,000 miles is more than just "piece of mind". It's just common sense. I paid 29,000 hard-earned dollars for my car, so neglecting it is not an option.

I forgot to mention that at 5000 miles I switched to full synthetic.

Nonsense. "The book" (aka the owner's manual) says what Ford recommends you do. They're not going to tell you an oil change interval of 10,000 miles is OK then void your warranty if you don't change it at 7,500. That would be patently ****ing stupid and would practically invite all of their customers to sue them.

this is a load of crap. it's your dealer trying to scare you into giving them more money. the owner's manual says to change the oil when the oil life monitor says to, and gives a rough guideline as to when it might tell you the oil needs to be changed. Anyone who says it needs to be done on a set interval (and uses scary language like "warranty in good standing") is only looking to vacuum money out of your pocket.

I'll go 10k miles on full synthetic, maybe more depending on what those 10k were like but only 6k-7k, tops, on the blend. For the first change, some people have the notion that keeping the factory oil in for that 10k helps the break-in period but I don't subscribe to that. If it bothers you, I still wouldn't change it before 5k miles but after that, I'd feel comfortable with a 10k frequency providing I was going to the track.

Decades ago, the theory was to change the factory oil early due to casting grit from the manufacturing process. That isn't an issue since the process has evolved significantly.

My 2013 that I bought with 5,800 miles on it had the change oil light on. What would cause it to come on so early?
The car was very clean and owned by a 60+ year old, the stock tires looked almost new.

the oil life monitor tracks a number of things. a lot of short trips where the engine doesn't get good and warmed up will shorten the oil life due to contamination.

I change mine every 5k regardless. Had a 2013 V-6 and oil monitor usually said 50+% life remaining whenever I took it in. Car always "felt" better after a change, but it's your choice. As far as an oil separator, get one! I never heard of that before I got on this forum, but I got one anyway. Boy, does it work! Can't believe how much oil it catches.
