As an engineer myself, I'd be fairly certain a cost conscious company like Ford wouldn't call out such a high spec oil unless they truly saw the need. If it is only truly required for certain scenarios then so be it. So we know that the ECU
will dial back the engine if oil temp gets too high. What I don't know is if they move set point up in the track pack calibration to take advantage of the better heat resistance of the heavier full synthetic. I have been told that the regular GT (non BOSS) guys tend to run into heat limits at the track.

Paid good coin and special ordered to get the track pack, won't cheap out now.

I can't blame you there, however, mine is modified. I need a better oil for racing, RP HPS is for modified street/race, and XPR is race, I don't race enough to justify the cost of running XPR all the time. However, those oils all have performance additives which will typically void warranty. Pretty sure I did that adding a supercharger and a custom tune.... :drool2:

Hmm, I just read this, be curious if anyone has actually done true testing on it. Almost everyone I see that races uses Amsoil, or RP's race oils.

I did more searching and found other stuff that gave different info. Some like the valvoline, others don't. Don't think we are going to find any articles that are spot on. This is the first mention I have ever seen that Valvoline VR1 is awesome, most people go Amsoil, or RP, and I have been happy so far.

Base model 5.0 using 5W20 ....... FTW :signs6:

5w-20 pennzoil ultra here!

So just so I understand this correctly. The exact same car/engine requires a completely different oil because it comes with better brakes, sway bars, and other handling upgrades?

It's the idea that the car will be tracked similar to the boss: heavily. Or at least it was built to be tracked heavily. I don't track mine much so I use Amsoil 10.40 Sig Series

It's a precaution because track condition are more severe.

Funny thing is, technically the warranty is void when you have an issue due to racing. Lol. Why should they care?

What about daily driving street conditions?

-Alex

Shit I use 20W50 amsoil.

I got a little better pricing from the Frisco Ford dealer's parts department last time I bought 5w-50.

I'm track pack too, and I'm stickin' with Motorcraft.

For everday driving 5W20 is good, if you take it to the track/course or whatever a thicker wieght would be the choice.

If anyone wants a to take there oil anlysis to the next level let me know. On the weekend once a month (Drill for the USAFR) I can burn a JOAP of your oil sample.

We do this after every flight on the F-16 to give us info on the engine.
