Just picked up an '06 GT 'vert; lovin' it (duh). Was wandering through the owners manual and see that they recommend 5-20 Motorcraft synthetic oil. Does the GT come from the factory w/ synthetics and when is everyone doing their 1st oil change? I have probably been overly cautious in the past; my Hemi Ram got it at 1,000 miles; the Harley I changed when I got home from the dealer (about 75 miles).
Just want to do'er right from the git go; when is it considered "broken in"?
i just got an 07 GT and i will do my first oil change at 1000 mi. I am also wondreing about the synthetic oil . once u use synthetic i think you must use it always. is this right???
The Ford oil is a synthetic blend, and any oil change at a ford dealer will be the blend. I did mine at 1000 miles, you can't be too careful. The engine power really wakes up after the 3000 mile change.

Can't be too careful indeed...I'm takin' Luci in for a full syn fillup today, with only 120 miles on her. The thought of that engine oil sittin' in the crankcase for a year gives me the willies. I didn't specifically ask (but should have) whether an oil change is part of the "pre-closing" prep of the car, but I doubt they had the bandwidth to do so. Salesman told me they had moved 15 cars on Tuesday and were looking at even more the day we bought (Weds.).
And yes, my understanding is that once you go full syn you should stay with it.
How many cars did I blow up back in my early/ignorant years because I didn't get the oil changed often enough? A lot...way too many. Not gonna make that mistake again, especially with these hot babes of mine...

That is a myth.
You can switch back and forth from synthetic to regular and back to synthetic every 5 miles if you want without hurting anything.
The car comes factory filled with Motorcraft synthetic blend (which is the recommended oil in the manual). Note that synthetic blend is NOT the same as full synthetic. I simply changed my oil at 5,000 miles for the first change as recommended by the manual. It was still golden colored and there were no bits of metal or anything in the sump. This isn't the 1950's anymore, you don't need to change the oil at 1,000 miles.
I chose to continue with the Motorcraft synthetic blend because it's cheap. Otherwise, I'd simply be using regular oil (Castrol GTX). My usual policy is full synthetic for turbo/supercharged and air-cooled applications where the oil sees temperatures above 350 degrees at times, in naturally-aspirated street engines, you'll never be able to tell the difference between synthetic and regular oil before 300,000 or 400,000 miles.

How many cars did I blow up back in my early/ignorant years because I didn't get the oil changed often enough?
Unless you ran them for 15,000 miles or something, the answer is "zero".
My father's '99 Explorer (302 V8) is running great at over 200,000 miles and we change the oil only when the onboard display says to (about every 7,000 miles). Hell, the manual for my '88 Honda that I used to have specified a 7,500 mile oil change interval. I se no reason to change the oil in any new GT any sooner than the recommended 5,000 mile interval.
And once again, the idea that you cannot go back to regular oil is a piece of automotive myth that has no basis in reality.

I had full synthetic until I read on this very site that the opinion was against using it. Something about the variable valve timing being affected by the less friction. I would like those persons to come forward so we'll know the whole story. As I remember, it was a very convincing argument...against.
have a 1993 toyota corolla that was mine and now my stepfathathers. This car was not well maintained, and oil changes are about every 8K. It has almost 300K and still runs good with no smoke or lifter noises. Oil changes are done at walmart or anyware cheap. I do use 5W20 Motorcraft oil in the stang, and would use synthetic, but i wouldnt change the oil every 3K, more like 5K...its just a waste of money, unless your racing it every weekend.

supposedly, the use of conventional oil or any other oil other than the synthetic blend recommended by ford may void your engine warranty due to the variable valve timing on these cars being controled by the oil pressure, and the oil pressure can be changed by switching oil weights and blends. have heard this from quite a few people, as DEA R&E did. at any rate, the syn blend is not that expensive and why chance it? ford knows thier engine and knows whats best for it. from my understanding as well, there is no benefit on our cars from running full synthetic unless you have heavily modded the bottom end of your engine and are pumping out some serious hp. 500+

Ford can't void the warranty for using an oil different from the recommendation unless they provide the recommended oil free of charge.

uh, okay. so ford recommends 5w 20 synthetic blend motor oil. you put in canola oil and the engine locks the f--- up, youre saying that ford will warranty you a new motor? because they didnt GIVE you the 5w20. id like to see that.
for all of you who didnt fall out of bed and hit your head this morning, i do know this for sure:
if you dont use fords recommended oil, and something happens to the motor, and they are able to trace it back to the oil, you are not just screwed. you are screwed royally. thats why i will use what the MANUFACTURER (ie: the builder, the creator, the assemblier, the developer, THE GRANTOR OF THE WARRANTY of that engine) says that THIER engine takes. if your engine says it needs 5w-20 senthetic blend, then that is what you need to use. ill say again, i think ford would know what oil is best for thier motors, you think they WANT warranty claims?
i suppose 66stang thinks that a stang running a tuner (sct or diablosport) with a 93 octane fuel tune doesnt need 93 octane fuel either, even though SCT and Diablosport RECOMMEND IT. so, by his theory of what RECOMMENDED means, you can run it on 87, and they have to fix any problems b/c they did not supply you with 93 for free!!
oh yeah, and ford does NOT have to supply you with the oil for free, however, they cant make you use thier brand. any brand 5w-20 SAE synthetic blend will do.

They do not specify "synthetic blend". They specify an API oil grade and a viscosity. Any oil that meets the specified API grade and viscosity can be used without voiding the warranty regardless of whether that oil is regular, semi-synthetic, or full synthetic.
HOWEVER, it is theoretically possible that only synthetics or semi-synthetics meet a specific API specification.
What 66Stang351 was saying is that Ford CANNOT mandate that you use their BRAND of oil unless they supply the oil for free. Any brand of oil that matches the viscosity and API grade specifications can be used in your Mustang without voiding the warranty, period. I can almost guarantee you that any name-brand 5W20 oil, regular, semi-synthetic, or full synthetic, will meet the proper specifications for the Mustang and will not void your warranty. For example, Mobil's non-synthetic (Mobil Clean 5000) fully meets Ford's mandated specification WSS-M2C930-A for use in the Mustang's V8.
oh yeah, and ford does NOT have to supply you with the oil for free, however, they cant make you use thier brand. any brand 5w-20 SAE synthetic blend will do.
That's what he was saying.
However, if Ford says that only their brand can be used, then they are required to provide the oil for free.
Also, as I pointed out, there are conventional oils that meet Ford's specifications, you don't even have to have a synthetic blend.

I just changed the oil and filter today. This was my first time in the GT and it took a bit longer than any other car I've done in the past. It took me ages to find the drain plug - the car is much lower than stock so its difficult to see without a pit or lift stand. I had to jack up the car on one side slightly to get my oil drain tank in. After that it was smooth going although the filter was a bit awkward as there is a hose on the way. The K&N filter has a 1" hex on the end but you will need a 1" spanner - there is not enough space for a socket and driver.
I added a fully synthetic Castrol Syntec 5W20 - just under 6 quarts so far and a K&N filter which seems to be very well made.
You can see from the photo that the recovered oil is definately used - this was the first change since new (11/05) and probably should have been changed ~ 2500 - 3000 miles - new owners take note ! I'll keep an eye on it but this should do until at least 7,500 on the clock. Changing the oil the week after you collect the car is OTT IMO !
