I have a 2013 F150 with the 5.0l engine.
I was annoyed it was an OHC engine. I was happy to find out that it is a chain, not a belt.
Having said that, the primary reason for changing belts is the engines are interference fit engines. Meaning, if the came does not move the valves, and one valve is open, the piston will hit the valve, causing serious internal damage.

Are the 2013 5.0L engines interference fit engines? Anyone have high mileage on theirs? I have 160,000 km on mine.

 

The timing chain will last the life of the engine if its properly maintained

 

And how do you properly maintain it?

 

Regular oil changes is about the only maintenance you can do, but it is crucial. Not sure about the interference parts.

 

I do mine on time, if not early.

 

No need to ever change the chain.
Following the OLM for OCIs and it will be fine.
The 5.0L has a very good reputation for good reason.

160k km? Yours is just now broken in!

 

Now 195k km. OCI?

My oil life monitor never tells me it is time. I get it done 6000k whether it needs it or not.

 

OCI = oil change interval.


Presuming you're doing 6,000 kms, it's probably a waste of good oil, but if it makes you feel better, go for it.


The 5.0L engine has a huge sump; way more than most engines. You could probably easily go 16,ooo kms (10k miles) and not hurt the engine.

 

Oil is cheap. Engines are not.

 

True ...
But waste ins't cheap, either.

Changing oil overly-frequently has never proven to save anything from death's doorstep. While it won't hurt the engine, it will most certainly hurt the wallet. If the OP is doing an OCI at 6,000 kms, (about 4k miles) that's a total waste of good oil.

If the mantra is to change oil often, then how "often" is "often enough"?????
Every 5k miles? 7k miles? 3k miles? 2k miles? Without knowledge, there is nothing but guessing.

But don't take my word for me; get a UOA and prove it to yourself!
I've seen a lot of UOAs on the Coy engines; they are stellar performers overall. Wear very well. Helps to have such a large sump. They don't need super-frequent OCIs to stay very healthy.


But hey, why let facts and data get in the way of a good ol' fashioned myth?

I am the OP.

I get nothing when i google UOA.

I have had other engines that people are surprised at how high of a mileage I get them to, and they still are running great. The secret was frequent oil changes. I follow the adage 5000km/3 months. The manufacturer recommends 6000 km/6 months. With the amount of driving I do, I never reach the time.

My truck is almost at 200k km. Oil changes are about $60. A engine replacement is about $7000. So, how many unnecessary oil changes would I have to do to equal a new engine?

I live in Canada where we get really cold winters. I know that as oil degrades, it looses some viscosity at outer ends of the temperature range.

So, yes, I would rather spend money on the extra oil than the engine install.

 

I cannot discount your experiences, but I can cerrtainly assure you that your anecdotal "evidence" isn't supported by large reams of facts.

- I've got a 2005 MGM that has 240k miles on it, and get's OCIs every 10k miles with dino oil. UOAs show it's in great shape. Changing the oil every 3k miles cannot make it any "better" than the already great condition it's in. That you change oil every 3k miles is no more or less the attribute that saves or harms an engine. Overly frequent OCIs do not show ANY (none, zip, nada) evidence of making a piece of equipment last longer.

- oil does not "lose" some viscosity when cold; the lube vis is altered by the VIIs (viscosity index improvers) and contamination (soot/oxidation). Typically, as oil ages, it may thin due to VII degradation. Or might thicken due to insoluble increase. It's too vague to make just a one-size-fits-all statement like yours.

- When under warranty, I certainly agree it is prudent to follow the OEM OCIs. After that, the whole " ... or X months" thing is a waste. There are plenty of examples where OCIs have spanned 3-5 years in use, and no ill effects have come from this.

- I am currently running an experiment between conventional and syn lubes, in extended OCIs, on both my MGMs; so far, there has been no statistical difference between the data streams.


In an overall sense, what you are doing to your engine is not harmful. What you're doing to your wallet is harmful. You are throwing away perfectly good oil (presumably the filter also). You are under the false presumption that if something is good, then more of that something must always be "better". TOTALLY WRONG when it comes to oil changes. The longer the OCI, the lower your wear rates go. Yes - you read that right; longer oil changes actually give a return of LOWER wear rates.

But again - why let facts and data get in the way of good ol' mythology and rhetoric???

I've decided to follow a 10K OCI(which seems to be inline with my OLM). However I am running Mobil 1 full synthetic.

 

I just read an article this week that gave the same info I've read from engineers in the past. Oil gets dirty/contaminated. All new car manuals I've read give "guidelines" depending on how the vehicle is driven/used. My thought is just make sure to do regular oil changes using the manufacturer guidelines as a starting point. I know guys who have oil tested at 10,000mi. and it is still OK. When I was a kid we ran a gas station and the oil drained out of the old 1960's-1970's engines was always BLACK which says contaminated/dirty. My oil changes now with modern cars will rarely see oil that is more than just dark. Engines run a lot cleaner now. One of the comments I've read from the oil experts though say your used oil should look dirty, that means it is working. I do 5,000 mi. or 6 months whichever comes first ( that's also easy for an old man to remember) and I do believe I waste good oil but still have the old guy better safe than sorry idea.

 

New engines are made with much tighter tolerances than the old, so the best benefit we get today is better sealing rings. So with less blow-by, the oil tends to stay cleaner and last longer. In addition, there's less wear because of the higher machining precision, so you should see less metal particles in the oil.

Ford claims that the engine in my 1987 Mustang GT can consume a quart of oil in about 1500 miles, and that was "normal". The reasoning being that this is due to the lubrication of the cylinders with the low tension rings, and the slightly looser fitting forged pistons. They replaced the loose forged pistons after a few years with more precise fitting rings and hypereutectic cast pistons, and the oil consumption went way down, and stayed cleaner to boot.
