Almost 30k on my 11 and same thing, drinks about 1 quart between changes (normal for the way I drive

For the price difference between the 392 and the 5.0 you could buy a new coyote motor 4 times.

Re: Engine seized! 2012 gt 5.0

using oil is not normal. I have had cars with over 200k on them that didn't use any oil between oil changes....at every 5000 miles

New 5.0 uses 5w-20 your car with over 200k on it was most likely using 10w-40 or even 15w-40 big differences in oil . Bearing clearances are very tight compared to older vehicles hence the oil weight difference.

Ha ha, yes Dodge and Mitsu have a very interesting relationship. I had an evo and can testify of how awesome those cars are. When my evo was stock it was taking Camaro SS's to town. I know they are rated at 290 hp but I think this is very underated or they are just super aerodynamic. After a bigger tubo (FP RED), exhaust and tune, that thing was pushing close to 400 WHP. And that cost only like 3500 dollars to do. Only problem is that the clutch sucks! So maybe it's more like 4500 dollars after a clutch upgrade.

Doesn't matter what the viscosity of your oil is it still shouldn't consume oil that's not normal. And the specs for oil Clarence on main journals hasn't changed that much to be honest with you the change to lower viscosity motors was more because of the valve-train components

You fail to understand the point, thinner oil will be reconsumed in the combustion chamber quicker than thicker oil.

That sounds reasonable, if the oil is thin, it would have a better chance o sneaking by the rings.

I just checked, I bought my 11 5.oh with 4800 and now I'm at 6800 Looks like the selling dealer never changed the oil, its time to change it, but its all there!

The oil is thinner because they designed the motor for it. These motors run up to 7000 rpms. That's a lot of oil to get to the four cams up top quickly. The thinner oil should drain back quicker to the sump as well. All I know is you can't just stuff thicker 10w30 or 20w50 in it. It was designed for the thin stuff. I had oil consumption issues in my 99 cobra and that ran a thicker weight oil from the factory so it's not a thin oil issue. My 99 was using up 2 quarts in 3000 miles and ford said it was "normal". This new 5.0 has been pretty good so far. I think it used a little more oil when it was new and breaking in. Now I am probably seeing about a half quart down over 5000 miles. You are going to have some loss in the engine. No engine will run to 200000 miles and not use at least some oil, even if it's 1/4 to 1/2 a quart. Performance engines will typically use more with the rpms and stress they are put under by the driver too. Mom's soccer van motor isn't getting opened up and pushed nearly as hard as the typical sports car engine.

Re: Engine seized! 2012 gt 5.0

After reading all this, I finally got around to checking my oil...I have about 3900 miles on it now... did my 1st change at the dealer at 1300 miles... right now are 3900 miles I was about 1.5 quarts low :-/ I hope its because of motor break in...

You fail to see the point that there should not be oil present in the combustion chamber no matter if the oil is thick or thin oil. And just because it's thinner oil does not mean it will "sneak" past the piston rings either. If it is then something is not right and should be addressed appropriately to just brush it off and say oh it's normal for a motor to consume oil is just plain wrong.

It is normal for a new engine to consume some oil , I wouldn't expect it to burn much but most of what some would think is being burned off is what I have see to be people who are paid to change the oil assume that it only needs 5-1/2 quarts not 7+. and why would oil viscosity not effect burn off. I remember not so honest car dealers putting 50w in a car that burned too much oil just so it wouldn't smoke in order to sell it.

I do agree with you that people are not refilling with the proper amount of oil to begin with but my point is that thin oil in a new motor will not cause it to burn an excessive amount of oil maybe a minute amount during break in but not enough to show a major drop on the dip stick...like you said in an older motor yes I understand what your saying but that's because the motor internals are old and worn out and need to be replaced

Re: Engine seized! 2012 gt 5.0

I've used 5/20 in my '05 4.6L for years now & it has never consumed a drop of oil in 61+ thousand miles. Furthermore, my '11 PSD (which has the brand new 6.7L Ford Scorpion motor) has never consumed a drop of oil in 26+ thousand miles & diesels are notorious for burning oil.

That being said, I am with SSC182 on this one. Consuming oil, from a new engine or otherwise, is NOT normal, regardless of the weight of the oil in question. I've driven my '05 much much much harder than most Mustang owners will ever drive their cars & have never had a single issue with oil consumption. It sounds like a design or manufacturing flaw in the new 5.0 Coyote motor to me.

I've got an 03 mach 1 which is very similar to the 99 cobra and I don't use a drop. I'm running a 5w-20 castrol full synthetic. Engine pulls damn hard (intake and head work). I'm not far behind the new 5.0 and I run even with a buddys maro ss. That's gonna change in a week. Just dropped 1600$ at am in go fast goodies.

I think mine ran 5w30 and it always drank oil. I had oil consumption studies done and was rejected by ford. They said 2 qts in 3000 miles was ok. It needed to be 3 qts in 3000 miles. Well that motor spun rod bearings at 70000 miles. Something was wrong there from the start. I am ok with using 1/2 a qt over the span between oil changes but not 2. If the new one used that much i would be on them again.

Wow, 3 quarts per 3000 miles is horrendous! Whatever happened to the saying "an ounce of prevention!" You would think they would do something about it at 2 quarts to prevent engine failure later!

After reading about this and seeing all kinds off infamous "ticking sound" videos on you tube... Im really glad I got my 2010 with a problem free 4.6l and tried and true 5 speed manual, lol!

If you can..... Gives us an update on your progress with ford.... I'm interested to see how they are helping you out with the BS rental car issue!

That was my 99. This one has been great without a problem after almost 19000 miles.

Re: Engine seized! 2012 gt 5.0

I realize this is an older thread, but I'm new here and doing some catching up. I just read an article tonight that talked about why they are using 5w20. It's got something to do with using an oil misting system to cool the pistons. I don't remember the particulars of it, but that stuck out to me as a bit strange.

I've had my 2012 for right at a month now. I've put just over 1000 miles on it and I'm going to have the oil changed this week. I've got a pretty good relationship with a service writer at the local dealer. He really knows his stuff. I don't even bother to talk to the others there because they are morons. The service manager used to be a crew chief with ford racing so I'm feeling pretty good about them taking good care of me. Besides, this is the third new car I've bought from this dealer in the last 2 years. They know me well and greet me by name when I walk in. Ford says to change the oil at 10,000 miles!!! No way. I'm changing it now, then every 3k. They said it has two different specs for oil, either full synthetic or synthetic blend. I've been checking it once a week and not a drop being used. This makes me a little nervous though to read all this. So far so good, but I'll be keeping a closer eye and ear on it.

What you are referring to is piston cooling oil jets, which have been used on motorcycles for years on air cooled motorcycles, including the famous GSX-R 1100cc motors that are no longer made but still a fav of drag racers. What I'm getting at is that is not by any means new tech, will it cause oil consumption? Not to my knowledge..

The article I was reading was just talking about the technology being used. I'll have to find it and post the link for it. It told the whole history from how they came up with the name coyote, all the way through the development and testing of it. Again, I'm new here, so it may have already made it's rounds through the forum.

I wasn't saying that it would cause oil consumption, I was just referring to why they use such a thin oil. My old bmw used a very thin oil too and we had a lengthy discussion over that on the bmw forum and it was because of the close tolerances and the speed that the oil moved at to cool properly.
