Downsized engines=shorter life?

[brown40]

I remember one of my early older coworkers talking about displacement, number of cylinders, and engine balance with me as a teenager. His perspective, which struck a chord with me, was that higher displacement with more robust components was important for folks doing a lot of hauling, that 6 or 12 cylinder engines hold up better because they can be built innately balanced, and that 100k miles on a 4 cylinder is 25k per cylinder, where on a V8 each carried 12.5k. I know real world its not so simple, but I do know running a motor at 60% maximum output is easier for heat and wear than running at 90% maximum.
I'm curious as well to see what such exceptional engineering, tuning, and hopefully metallurgy will lead to in the long term. Corrosion seems to be what ultimately does in most vehicles in Maine, before the engine or powertrain performance starts deteriorating noticeably.

I think extended warranties are a ripoff for low mileage drivers like myself.

I would generally agree with you. But in the past, turbo charged gasoline powered vehicles used to not have a very good reputation for durability, so I let the dealer sell me an extended warranty on the 2014 Escape (which was a rental car that I bought with about 17k miles on it). And now this 2015 F150 was one of their demos and had 10,088 miles on it, and with the refund from the Escape extended warranty, it only cost me another $250 (instead of taking the cash refund).

No... it was that common light green metallic...

As for smaller engines affecting engine life I'm thinking a lot depends on engineering as in how robust the design and how durable the materials...

Plenty of high mileage little Japanese pickups round that were simply beat... had a Chevrolet Luv pickup that was falling apart except the drivetrain just would not quit...

Another way to look at it is how many GM Diesels from 1980 are still around compared to Mercedes Diesels?

If they build a 5.0L Ecoboost, that will be the end of the Powerstrokes.

I've owned 460 Ford, 454 Chevrolet, and 440 Chrysler products in the past, but been driving a little 2001 Ford Ranger with the 4.0L engine the last 10 years, and a 2.0L ecoboost 2014 Ford Escape the last year and a half. But we really haven't needed 2 vehicles, although I do need a pickup occasionally, and sometimes the Escape was a bit too small, so yesterday I traded both of them for a 2015 Ford F150 Supercrew with the 2.7L ecoboost.:laughing:

But I did pay a little more for a 6 year, 100k mile, bumper to bumper warranty.

Did they give you a free turkey? Its that time of year, you know... :laughing:

Good, I was about to weep uncontrollably. :laughing:

I was always one that leaned to the larger last longer. The Ford Ecoboost is not giving people a nightmare that I hear about locally and actually they are loved by the ones I speak with. Sometimes new data calls for a new decision.

 

[MossRoad]

Well, we'll have to wait and see if it hits over 100,000,000 produced like the Chevy smallblock did about 4 years ago...

I guess I'm gettin' old and forgetful; didn't even think of that, even though a couple of years in the last 10 they sent me an email to stop by for a free turkey.:laughing:

Worried over a non issue. In the good old days up into the 1980's. A carburated leaded gas engine needed a valve job by 75,000miles. If the bottom end of the engine made it 100,000 miles. It was a clanking wheezing oil burning clunk.
Now gasser's going 300,000 miles , running good and not burning oil is normal. Everything last longer and is more reliable . Good Old Days my &&&.
