5w50-ouch

[JDBishopArts]

I'm running 5w20 Mobil 1. Always run Mobil 1 with no issues. On boosted and non boosted cars. I wanted to run Amsoil but I couldn't find a dealer that didnt' want an arm and a leg. I'll order it next time.

The track pack does require you run ford recommend oil to retain the warranty.

If you heavy road track your car is it recommended to run 5w-50? Just curious, anything to help my overheating problems on the track. Currently run 5w-30.

Doubt that it will help the overheat, but should help protect the engine at the high temps.

If you are having that big of an issue with heat which would not surprise me with the large intercooler in front of the radiator. I would suggest going with a larger radiator along with doing a remote mounted oil filter and adding a large air to air oil cooler. That should remedy your heat issues.

We can get you the components needed for this modification if you are interested.

Oh and yes run a thicker oil when you track it. It may not affect cooling but it will definately help to protect the bearings will the huge amount of stress you are putting them under with the power and extended runs at the track.

I wanted to jump in and give some useful advice on this thread regarding the 5w50 motorcraft.

Ford is obviously going to recommend their own brand. But this is an "intended use" package on this car, and therefore Ford assumes at least one of us will actually do extreme track work and doesnt want the motor seizing up. Currently, if your a worry wort about your warranty, you can only use Motorcraft 5w50 or you can use the Castrol Syntec 5w50. These as far as I know are the only two Ford will recognize as being covered under warranty due to the specific certifications.

However, UOA's have already shown that 10w30 Amsoil, and even Royal Purple are superior, at least on the analysis sheet. Ford's engineers are not stupid, but what their not telling you, is about the quality of their oil. Under street racing conditions or light tracking, the 5w50 Motorcraft is shearing to a light 5w40 at running tempurature. Under extreme conditions, its even shearing down to a heavy 5w30.

By this, I would rather run a quality oil thats ALWAYS a 30w oil with minimal shearing. Amsoil 10w30 is my choice. And the 10w is soley because we live in Texas.

With a quality 30w, your going to have the same if not better protection, and slightly improved fuel mileage. If your worried about warranty, you can use the cheaper Motorcraft. The same engine runs 5w20 in non track pack AND non boss cars. They assume its your daily driver (the base model), not a race car.

Pick the oil for your intended use, and pick a quality one.

They don't expect boss cars to be on a track???

You misunderstand

The same engine is in all three trims. The oil changes to 5w50 in their higher trims because they expect them to be driven hard.
I think you know what I meant.

Let me ask you this. WHat kinf od wear does that 50 put on an engine at startup?

At startup? The 50 isnt as relevant for startup protection as the the first Winter grade number is, and what your particular climate is. Startup engine protection relies heavily on the cold viscosity of your winter grade. Not sure if your attempting to troll or what, because you have yet to actually tell me where the flaw is in said knowledge. If the next response is anything but, I will probably move on to other, more important threads.

Not trying to be offensive at all. But when someone shares knowledge of something they have looked deeply into to help those with questions, theres usually better and / or more detailed responses then "You guys are all very off on your understanding of motor oils." How about you share your knowledge, instead of making a generalized browbeat of others, and leave some details as to how you came to that conclusion.

Anything helps at this point. With the recent quote on my hail damage from USAA ($1k) I will be going to a collision place for a full quote. If they can cut me a better quote, I will just keep the cash as the damage is hard to see. Use that to fund maybe a new radiator and tiger racing hood. Trying my best to cool the engine down, so if the oil can help, I'm all for it.

Paceline on veterans is really good(they've done the work on all my cars) but they're pricey. Might wanna see what caliber quotes, I've heard they're good too

I have track pack as well and I'm sticking with factory specs as well. There is a brand called Redline that a lot of ppl swear by but I've also heard there is a Mobil 1 in 5w50. I know for sure that there is no Royal Purple at that weight

Hard to argue with oil analysis. But do educate me sir.

[Crimson600+HP]

I didn't know that the Boss and track pack cars ran 5w-50 for protection reasons. Given the nature of how I treat my car, I think this is probably the right move to do.
