2014 - 2015 gas engine life expectancy?

What do you all feel is the life expectancy of the new gas engines in the Super Dutys?

I'm thinking for
~30,000 mile a year driver
mostly highway
no major towing, just ladder racks and some tool boxes.

I've been a diesel pickup owner for years so I'm curious what you all would be happy to expect from a new purchase.

Thanks.

Any number of things could happen that could make that number vary quite a bit. Catastrophic engine failure do to one bad part, driving style, maintenance of vehicle, quality of replacement parts, etc. But over the past 20 years I think the durability side of the argument has swayed in favor of the gassers. That was true back when the 6.9 and 7.3 would run forever and the carbed 302 was only good for 70-80k miles, but that argument is still used even though it is now the gassers that are running hundreds of thousands of trouble free miles.

So basically it's much better than the 100,000 - 150,000 miles of the last decade or two, and much better than the 70,000 - 90,000 of the decades before that?

I'm looking at getting a new truck, and if I do about 35,000 miles a year then in 6 years I'll be at about 210,000 miles. I'm afraid a gas engine truck would be junk by then. Is that not true with todays gas engines?

I don't think 2-300,000 miles on a properly maintained gas truck is out if the norm for newer trucks. I know your not looking at a 5.4 but my truck has 100k and there is nothing about it that leads me to think it won't go another 100-200 no problem

It has also spent its whole life, with side boxes and ladder racks, towing and plowing.

We have a 98 mountaineer with 234K on it and not a lick of oil being burned.

I'd expect todays gas motors to last well beyond that with proper maintance.

My thoughts are consistant oil changes, trans flushed and transfer case. I would not go the recommended factory service intervals though.

I know that goes against all the recommendations but it has served me well.

with proper maintenance you shouldn't have any trouble getting over 200k out of the 6.2.

Completely agree with the above, modern gas engines can last a LONG time.

Million Mile Van.

I have a 17-year-old Lincoln with 150,000 miles and the engine runs like new with no noticeable power loss. My mother in law has an '06 Grand Caravan with 210,000 miles and no issues.

There are lots of owners of high mileage gas trucks here on FTE, and from what I've seen the average life expectancy easily outstrips modern diesel engines. I can't remember ever reading of someone who wore out an engine and replaced it due to low compression or oil pressure. But I've read hundreds of threads over the years of blown up engines, and the overwhelming majority of them are diesels.

I feel engines will outlive the interior's seats and the fancy electronics will likely drive you to another vehicle

Starting with the 5.0 Ford made a lot of improvements to the gas engines and seeing 300-400k miles on a roller Windsor or on a mod motor is not out of the ordinary. I have 250k on my bronco with no engine work other than plugs and wires and 150k on my van (5.4) with nothing but plugs and one coil.

Running highway miles is easy on the engine too. Fewer cold starts, more time running at operating temps and less stop and go driving. I would be surprised if the engine didn't outlast the truck.

I have to agree that 300,000 miles is a very realistic mileage out of any modern motor. Just look at the 4.6L, Used in Crown Victoria, Mercury Grand marquis and Lincoln Town cars. Police beat the snot out of those motors and rarely shut them off, only really to service them. They will go from that to taxi use usually and get run for another 200,000 miles. Its common for them to be auctioned to the public after that and keep going.

I personally have a 2003 Crown Victoria Police Interceptor with 295,000 miles on it. It was a Missouri State Police car that spent all day idling and going 0-100 to catch people speeding. It was auctioned off at 120,000 miles then put into taxi service. I bought it from the taxi company expecting it to be a total junker, I was wrong.

The basic concept of the Modular platform has been around since 1998 and even though the 5.4 and 4.6 are no longer around in new vehicles, the 6.2 is the same proven design and concepts since 1998.

More like 1992. My '97 Lincoln has the same 4.6L V8 that your CV does.

Sure it's an SOHC V8, but that's about where the similarities end. This is from Mike Harrison, the chief engineer for the 6.2L V8:

You should get around 240000miles ish. Some of our company 5.4L motors have just shy of 400000km which is about 240 miles. These get run hard by multiple drivers and at that age they burn about 1-2 quarts oil per 3-5000 mile but still run good. We wear the chassis out before the motor.
