Looks like he couldn't even get his non track pack car to enter limp mode and never saw temps over 230. And the analysis showed the 20 viscosity oil doing fine.



Yes very relevant, a real world example that 20 weight provided excellent wear protection even though it was ran hard.

So what's the answer?
There is no one answer. This is because either oil will work for the OP.

This same topic, admittedly, has been thrown around alot, but maybe it is different for different vehicles. For instance, my truck's engine. It was originally spec'd for 5w-30, and then was backspec'd to 5w-20. I use 5w-30.

Instead of asking "why," ask "why not." If the OP wants to use 5w-30, I honestly think that's fine.

Well said. It is only fair to attempt to be impartial and weigh the information and make a common sense decision.

Yes, the warranty calls for 5w20 and a 30 weight isn't allowed for in the owner's manual - <IN THE US>. Yes the FF is 5w20 and the Track Pack specifies 5w50.

I didn't see anyone saying what the Euro or Australian specifications are for this engine. Did anyone bother to look? There are plenty of threads where many other Ford vehicles are supposed to use 5w20 in the US, but overseas are using much heavier weights.

Bottom line question: will 5w30 do harm to the engine? IMO it will not.

I hate to add some confusion.
And I'm not sure what the owners manuals say.
I'm surprised at how much oil is in these things (8.5 litres)

But I just did a quick and dirty check of some different oil company's website recommendations out of curiosity.

Castrol don't make a recommendation, but they refer you to a phone help line.

Valvolene wont make a recommendation, but say to "refer to dealer".
But for the 5.4 litre they say to use a 0w-40 grade.

Shell recommend Helix Ultra in 5w-40 grade for 2008-2009 model years, but nothing after those years. Perhaps it's only for the 5.4 litre engine?

Mobil recommend Mobil 1 in a 0w-20 grade.

Penrite recommend an API SN 5w-20 grade that complies with Ford spec's M2C925-A/M2C930-A/M2C945-A.
And they also recommend an API SN, ILSAC GF-5, GM dexos 1, 5w-30 grade that complies with Ford spec M2C946-A, GM4718M/6094M.

It would seem the options are wide open, and a 5w-30 grade wouldn't necessarily do any harm.

I do note the different Ford spec's, that apply to the different grades of Penrite oil they recommend.
I think Penrite are conservative in their recommendations at this stage in that the 5w-20 grade will be for while the vehicles are still under warranty, whilst still leaving the door open to the use of a thicker oil.
I'd be willing to bet, they would be inclined to drop the thin oil recommendation after the vehicles are out of warranty and just go with the 5w-30 grade(or thicker?) as they are inclined to do.

I thought about that. No one can get their GT into limp mode when tracking it. The track pack GT would be even harder to get oil temps up that high with the upgraded cooling. Why the 5W-50 recommendations if 5w-20 is the ideal weight for this engine? If you just needed a little margin for error you could have spec'd 5W-30 syn.

A legitimate question. A question for which we will never have an answer for short of speculation. Much like Whitehead's remarks about using a 20 viscosity oil we just won't ever have much to go on because he didn't share any additional information explaining his statements in detail. I think we'll just have to do the best we can on the information we have at our disposal. The real world results we can share amongst ourselves.

Bottom line. The engine will tolerate a range of viscosity. You will need to keep using the 20 if you want to maintain warranty support. The 20 will not harm the engine either. There are no oil related failures due to using the 20 viscosity in this engine that I am aware of.

At this point I'm thinking about sticking with the 20 viscosity now. If anything because the real world results don't seem to show any reason not to.

This same topic was covered before,do a search.You can rehash subjects only so far. And I'll say it AGAIN as well,this is how other members feel as well.New information is good,but we re-hash everything.

5w20 vs 5w30 threads are beat to death around here for just another example.I could list more,but frankly I dont have the time.

This engine is used in the FPV FG Falcon in a supercharged form in Australia, they call it the BOSS 335. Ford recommends Castrol Edge 5W20, which apparently is not easy to find in reading some forums.

Yes the engine is indeed a supercharged 335 kw variant that's fitted to the current FPV(Ford Performance Vehicles) FG Falcon GT's.

5w-20 grade oils are not readily available here.
I've never seen the Castrol Edge 5w-20 grade oil sold in retail packs before, so i
just looked up the TDS for it.
I also see that the Head of Programs for FPV, says that this oil is the only one that's recommended.

It looks as though it's most likely "the oil" that's used at the dealers as a service refill, and probably only comes in a 200 litre drum at this stage.
It meets Ford spec M2C930-A, ILSAC GF-4, API SM.
It's stated to be a part synthetic.
Castrol also state, that it's been specifically co-engineered in partnership with FPV for the latest 5.0 litre V8.

More interestingly there's a special note that states "Castrol Edge 5w-20 is not recommended for diesel engine applications or petrol engines where higher viscosity oils are recommended; e.g. 10w-30, 15w-40. etc."

They must think it's too thin to use in other applications that are engineered to use a thicker grade of oil?

It's certainly food for thought.
After looking this up, I would be inclined to think there's no practical advantage in using a thicker oil in this application.

I also have a 2014 GT non-track pack car and use 5W-20 Motorcraft blend. While the car is under warranty, I will continue to use a 5W-20 that meets the Ford spec. I have already had to fight with Ford to fix a minor warranty issue on this car so I don't want to give them any ammo by using something other than the recommended viscosity in case I end up having an engine problem.

I'm also not going to claim I know more than the engineers who developed this engine so I'm going to stay with their recommendation.

Vehicles have been using 5W-20 for years with no issues and since Ford has back speced a lot of their engines to use 5W-20, to me shows that they have confidence in this viscosity.

I don't think they did it for CAFE reasons since it shouldn't apply in used vehicles.

To the OP, I would stay with the 5W-20 at least until the warranty is over and then do what you feel comfortable with.

My son-in-laws new F250, full four door, 8ft bed, Ford truck has the 6. something engine and it calls for 5-20, and there are no cafe requirements for it. No fuel mileage guesstaments came with the truck. He will use this truck for very heavy hauling and he will use M1 5-20 the first OC. A 20wt oil will be fine for your Ford as well.

Wow...4 pages in this post and less than 5 answers to the OP's question is pretty pathetic, and a reason to lose members. To answer your question Riptide, this great UOA was posted yesterday on a 5.0 Coyote.

You didn't help answer his question either. He was asking about 5W-30. And I wasn't too thrilled to see 1.6 qts of make up oil. I'm 9K in and haven't burnt any noticeable amount of oil. Maybe he was driving it hard.

Actually, he didn't.... not ONE SINGLE POST of him asking our opinion on his use of 5w30.....but I'm not gonna argue with you like a child.

I have run Crown Vic Police Interceptors about as hard as you can run a car on 5w-20. I have also run them mighty hard on 15w-40. The old modular 4.6 didnt care a bit what was in it. That engine didnt have VVT and all that new hotness though. I currently have an E350 and an F250 both with the 5.4. They both get Mobil 5w-20 if that tells you anything about my opinion.
