Oil and Lube
I have a track pack car and I am wondering what oil and filter you all are using? 5w50 full synthetic is not a common oil. I have been a valvolin user forever.
Also What lube, Grease are you using?
Filter?

Here we go again :grenade: 
I'll save some people the trouble of posting. Use the search on the forum there's many an oil thread floating around here, especially about cars using the 5w50

No problem and I mean no harm by it. Usually people on here go crazy when another oil thread gets started. I'm preferable to royal purple oil and motorcraft filters myself but I just have an 03 mach, 04 v6 and 95 GT so I don't have anything newer to know who even makes a 5w50

Go on SVT Performance and do some reading. We have some good threads going on oil with one of them having independent tests done from Blackstone. Once you see the results you'll realize 5w-50 is not the best choice.

I agree it is not the best choice. We use to own a union 76 station for many years. Studied oil and fuel then. But to keep the warranty I am told to use 5w50 till the warranty runs out?? Living in Florida I am never in need of the cold number.

The problem with Motorcraft's oil is that their 5w50 ends up shearing down to about a 30W oil by the time you pull it out of your engine. Some have suggested that, as a result, a 40W is probably ideal for the car as long as it's a PAO-based synthetic. I run 10W40 in mine both because the weight is suitable to the stress to which it will be subjected and also because that's what John Lund told me to run in my engine. As an engineer, I just happen to agree with him (and Blackstone labs).

Of course his warranty is void already anyway
And the inside of his car smells like corn dogs

OP, I believe the GT's also take the FL-500/500S but you can use the GT500 FL-820 or whatever the part number is for that size filter.

Besides - you're driving a supercharged GT500 - not a GT track pack, right?
Isn't the purpose of the 5w-50 for the GT track pack to counter the heat from extended duration high rev racing at a track? Not so the oil would stay at a 50w...

Why is that bad? You make it sound like Ford wants it to stay at a 50w.

I ran M1 5w50 for 4900 miles including 350 road course miles and then had it tested. It was in good shape. I have the results posted on this forum somewhere...
Running Motorcraft 5w50 right now cause I got 3 free oil changes from Ford (I changed to M1 at 450 miles on the car). I will probably change out my current Motorcraft oil in late July after ~2000 street miles and 500 track miles and will have that analyzed as well. Going to Castrol next to try that out and will again have that analyzed. I am an engineer so I like data...
That all said, I've had no issues with oil consumption on my car up to this point and I drive it hard. 7030 miles on the clock as of this afternoon.

It should be said however, that the replacement oil does need to be a PAO-based lubricant.

Well.....Being an engineer my self I love the data as well. I have seen some information on this forum and others but I am still wanting to know what others use. You all make valid points and I love to read what you all are doing. There are allot of great people here. So I thank you all for your input.
What trans oil Manual are you all using? What differential oil are you all using?
Thank you all.

And I use Blackstone on Bullitt to confirm all is well.

Again the monkey wrench in all this is track pack cars spec 5w-50 while non track pack cars spec 5w-20 with zero differences in either motors.
Non track pack cars in other country's spec 5w-30 because they do not need to meet the cafe standards like here.
Another thing to consider is not many companies have a 5w-50 oil so Ford Motorcraft kind of has a monopoly on the market. And it's been proven with independent UOA results that the Motorcraft 5w-50 shears to a 5w-40 in a few hundred miles.
