According to my drive today, the oil life monitor in the 2011 F-150 monitors viscosity rather than miles / time.

 

The viscosity changes as the oil heats and cools, I don't really see what that is supposed to accomplish.

 

I just brought home a 2011 f150 with the 5.0 on Saturday. It is the first new vehicle I have had since 1993 (5.0 lx mustang). I read the manual cover to cover looking to see if there was a mileage to change the oil after the break in and there was no recomended oil change after break in but they did say break in was 1000 miles. They never say 10,000 miles for an oil change it just says to change the oil when the oil life meter says to. It then says it could be up to 10,000 miles. It also says if that system does not work to do it at 6 months 7500 miles. So according to ford you should only change it when the truck says to, could be 10,000 could be 5000. I am still doing mine after break in then every 5000, gota make it last if history repeats it will be a long time till I get to buy again.

 

My wife bought a 2010 Explorer 4.0 in January. We traded in a 2009 Wrangler on it. The Wrangler wanted an oil change no longer than 5,000 miles. We bought it new and I only ran Mobil 1 in it. By 17,000 miles, it was drinking oil and losing antifreeze somewhere- common with the junk engines Chrysler threw in there. The Explorer has 5500 miles on it and the oil life monitor says 20% oil life left. I believe the change interval is 7500. I am curious how close it will actually get.
As far as going 10,000 miles, I personally will never do it. Oil gets dirty. 7500 miles will kill me. Unless you have some type of whoopty oil filtration, I would not risk an engine full of sludge (cam phasers and VVT- or whatever it is called) to save a few bucks. I will be in the market soon (wish it were now) for a new F150. After driving an EB, I am sold on the 09+ F150. Today, if it works out, I will drive a 5 liter. I am dying to know which engine I will lean toward so I have to drive both to be mentally prepared. But, as far as the oil interval, I could be wrong. Wouldnt be the first time!

 

Well, I drove the 5 liter and I must say Ford makes it hard for us to decide between it and the ecoboost. The pull from the 5.0 is awesome very similar to the ecoboost to me, although the eb felt a little stronger. Not by much. I havent driven an 09-10 5.4 but this 5.0 is waaay stronger than the 2V and 3V's I have driven.
I have some time to decide as I have to sell my Excursion to even consider getting one.

 

This may be a silly question, but I've never spoken to anyone who has actually driven an Ecoboost engine. Is there any detectable turbo lag?

 

I felt none. It was like it catapulted from a stop.

 

So, in the 5.0 vs EB debate, I guess the question becomes- "Is a little more power and a little more mileage worth $1000?" I'm still leaning towards the 5.0, but that COULD change.....

 

Even if less power and I think Ford is derating the potenial of the 5.0 in order to highlight the new V6, I would rather have a V8 and would pay more for it!

Instead of going the V6 route I think making smaller V8 would be better option
in pickups! With all the realibity problems Ford has had with TURBOS and only warranty them for 150,000 mile in todays world is not good, being a TURBO could cost thousands to replace!

 

Which turbos has Ford had problems with?

 

The 6.0 and 6.4 powerstoke Diesels I have mechanics say are a problem! Not to mention past Ford Turbo Coupes and Mustangs etc!

I know they say they are better now, but with all the complicated equipment to run a Turbo set up, if I was going to keep truck for years I would not buy a turbo gasoline engine!

 

These Diesel engines are NOT Ford-designed or built. They both came from Navistar (AKA International Harvester). And ALL Diesels on the road today are turbocharged, so don't point to that as a fault area. The reasons there are more problems w/ today's Diesels is because of incredibly stupid emission regs forced upon the mfrs that are total overkill. Whoever thought of the particulate trap ought to be shot......

 

Sir, what I was getting was the actual turbos not the engine itself. The 6.0L didn't have turbo issues as much as head problems on the earlier models. That was solved.

The earlier 6.4L engines had some issues but I haven't read of hardly any turbo issues.

The 3.5L EB engine has been employed for a couple of years now. I haven't read any negativity on this engine yet.

 

No I was talking about the engines themself, I have a business that works with some Ford Dealerships and the "turbo" has been a issue!

Plus water and oil mixing and other issues! In the 6.4, the 6.0 had various problems the turbo being one of them!

Ever owned a truck with a turbo? When the turbo starts going bad the engine will race high rpm and self destruct in minutes!!!!

Mabe some Ford service bullentins would be of help!

For me and my business realiabity beats efficency everytime!

 

The 6.0 had issues definitely with the variable vanes sticking and mainly EGR cooler issues. As far as a turbo going bad overspeeding an engine, isnt that on a diesel when a seal goes bad and it starts running on crankcase oil (diesel only)?
On the EB, this shouldnt be a concern. My 01 Excursion with the 7.3 has 161,ooo miles with the original turbo with zero issues. There are a lot of engines out there with turbos from the factory and have no problems.
