I've wondered how to tell the difference of engine in the newer trucks .. I've noticed that my 4x4 decal with the 6.2 is gold and on a co workers he has a 5.0 lariat and his decal is grey.. I know on the chevy trucks they all had different exhaust placement out the rear . Anyone know something I don't ???

 

Pretty sure decal color it depends on the color of the truck and/or the trim level. The 2013-14 bed decals are different from the 2012s

I can tell the 5.4 apart from the others by listening to it idle. The EB obviously has the badge on the door and sounds different. Side by side you can tell the 6.2 and 5.0 apart by how they sound at idle, but that's all I got. The only reason I know that is cause I work at a dealership and have deliberately listened for the differences from motor to motor. No way I know of to visually tell a 3.7 from a 5.0 from a 6.2. If there is one, I'd like to know it.

 

The thing is, my buddies truck is a 2011 black lariat 5.0 and mines a 2011 black lariat with the 6.2 ... The only thing I notice is, his says flex fuel and dark grey 4x4 decal. And I've only seen flex fuel on the superduty 6.2s...

 

Huh, maybe the 6.2 does get those gold ones! I think Scarlet's 6.2 has the gold ones, but his truck is also a Red and gold two-tone Lariat.

Do your trucks have a different two-tone maybe?

 

Man they are totally identical trucks.. Only things different are the engines.

 

Well that's enough evidence for me to conclude that the 6.2s get the gold. I wonder if the 3.7 and 5.0 all have different ones too.

 

Most ecoboost trucks doesnt have the 4x4 decals.. The reason?? These trucks are so damn fast the stickers just peel off the sides..

 

Or cause they're all 2WD street queens

 

ah come on you couldve come up with something better than that!

I'll just wait for Jim's reply

 

Well every single 4x4 that leaves the factory gets a 4x4 decal, so if a lot of them don't have them . . .

 

It is a bit harder to tell since they stopped putting engine badges on the trucks (except the Ecoboost, of course). I don't know if decal color is associated with the engine (I always thought it depended on the color, trim, and maybe even interior color), but I do know a few ways to discern between the 3.7 and the 5.0. For example, if you see a supercrew 4x4 without the Ecoboost badge, it's most likely a 5.0. The 3.7L is available in a crew cab, but only in 2wd. Add the 4x4 to it and you're upgraded to a 5.0. You can still get the 3.7 4x4 in supercab and regular cab models. Also, you won't find a 3.7 in a Lariat trim or above. I'm willing to bet the majority of non-Ecoboost crew cabs are the 5.0 rather than the 6.2. Perhaps towing mirrors could be an indicator as well? The 6.2 still has the hydraulic power steering, but that doesn't do you any good from the outside.

So I just read everything I typed and realized I have been no help at all, and now I'm just as uncertain as you

 

Wouldn't that make it hard for you to see behind you with your mirrors folded in all the time?? Seems like your Ecoboost badges would've blown off by now.

 

And now they have the 6.2 in the fx4 so I guess it's just a guessing game unless you can talk to the guy ... And as for the ecoboost stickers flying off ... I didn't even know they had them since I've never been stuck behind one ; )

 

In states that require front license plates you can tell an Ecoboost from a V8 by the placement of the front plate. Ecoboost is always offset to the drivers side of the front bumper vs. centered on the V8. Not sure what sets the 5.0 vs 6.2 apart though... Maybe the trucks sitting at the gas pump are 6.2 and 5.0 trucks drive by smiling and glad they didn't get the 6.2? LOL. J/K :-)

 

Haha I can believe that! Man this thing is a pig especially now that it's supercharged and I have to hear that whining every time I drive it. $$$$
