Ford dealer installed wrong oil
I recently took my FGT to a local Ford dealer to have the axle bolt upgrade performed. I had the dealer do an engine oil and filter change service at the same time. Last night I happened to read the repair order and to my dismay I see that the dealer used Mobil 1 15W50! Should I be concerned? BTW, I specifically requested that the service adviser be sure that the tech use the recommended Motorcraft # XO-5W50-QGT oil!
If it was my car - I would get it out ASAP.
John at Accufab tested different oils to find the Ford (Conoco supplied) is the best performing.
What I would be worried about is the differences between the two manufactures. Synthetic is a "big" group, many having totally different properties and residual affect if you move from one to another...
Good luck.
PS - Find a real service dealer

Get it changed
I agree with Mike!
I would take it back to the dealer and (forcefully if necessary) request the oil be drained and changed to the OEM Motorcraft oil.
They screwed up and after you specifically told them to use the Motorcraft oil, I would hope they would not challenge the request......

I would get it out and they need to acknowledge it in writing . I think it's a warranty issue if you do not use the Ford Oil? So they may have violated it ??
Check the manual and be educated before you talk to them .. Probably no damaged has been done but I would to have their screw up documented. Who knows. If there are motor issues down the road it would be wise to have this documented... just my 2 cent...

At least your belly pans and frame rails are OK, right?

Thanks for the input Mr. Mad & Mr. Indy! Before I called the dealer to complain I wanted to get some insight here on the forum. I thought that certainly a Ford dealer (which was recommended by other GT owners) would use the correct Ford oil without me instructing them to do so. However, being a little paranoid, I figured it wouldn't hurt to mention it. Apparently my concern at the time was reasonable. Not that it did me any good. BTW, I researched for some time to determine which Ford dealer to use for service and when I took my car in there were 4 other FGT's in getting serviced at the same time.
At least tell the dealer that going forward you want a real GT service tech not a Focus tech.or, have them banish the tech to truck land. If they don't respond properly use the weight of the Forum (not the moderator) to help you!

Thanks for the advice Stormcat. I was worried about the warranty aspect also!!! I was not going to mention it on the forum because I did not want to come off as a whiner. I agree that it is doubtful that any damage has occurred. Mobil 1 is a fine oil, it's just not the right oil, nor the right wt. (15W50). I will take your advice and check the manual. If recall the manual does say to use the Motorcraft 5W50.I would get it out and they need to acknowledge it in writing . I think it's a warranty issue if you do not use the Ford Oil? So they may have violated it ??

Believe me ICE Man, I will be checking the belly pans when I get home from work tonight! I'm keeping my fingers crossed (maakes it dfficult to type).
This oil will not harm the motor in So. Cal. IMO
I would be concerned with the 15W starting weight in the cold climates though. And maybe for torlerences until warm. But given the 50W top end, I doubt tolerances are an issue. The 50W is spec for the cars and it will be the same when the car is warm.
Until you drain it for the proper starting weight, (which BTW is a national avg. If they only sold GT's in Palm springs and did not care about EPA ratings they may have used a 10w to begin with. ). Let it idle longer to warm up. Once you are at operting temp it will not do any damage.
I think we are are a little paranoid about the oils. I have been selling motor oils for nearly 30 years, been to many labs and on many plant tours, dyno tests, wear tests, etc. The specs can be different in each blend, but the Mobil 1 is one of the best in the industry for an alum motor. And for the record Motorcraft does not blend any oils or chemicals. They are all private labeled something else.
Keep in mind this Motorcraft weight is odd and Ford does not use it in anything else high production. It will be gone ( not available in motorcraft) in a few years and we will all be using something else anyway. Until then, I will use the Motorcraft, with Mobil 1 being my second choice.
Don't panic...just have them order the spec stuff and change it again.
