Will a 2.4L Sonata engine make it 150K miles?

I have a 2002 2.4L Sonata. I'm curious, if I change the oil per the
manufacturer's recommendations, will the motors generally last for up
to 150K miles?

 

If properly maintained and not abused I'd say well over 300k, since
others have actually made it with that engine in the past.

The 2.4L will likely outlast the 2.7L V6. The 2.4 has a nice solid cast
iron block, the 2.7 100% aluminum. "Riceboys" claim the Tiburon's 2.7
(same engine) has some fairly 'hard limits' to deal with, supposedly the
block starts flexing in non-friendly ways between 225-300 ft/lbs torque
delivery. The block flex causes extremely high wear levels, causing
either a loss of compression or something important to break on the spot.

That little bit of news killed my "Hmm, I think I'll hang a couple
smallish turbos on my Santa Fe when it goes out of warranty" plans...

Yes, I agree that 150K should be a piece of cake assuming good
maintenance and barring one of those unusual failures that just happends
now and again.

I've had very good luck with 4 cylinder engine durability. Several of
the most durable engines I've owned (150K+ miles) were the 4 cylinder in
the Chevy Chevette (an Opel design, I believe), the 4 cylinder Jeep 2.5L
in the 1986 Comanche that I STILL use for hauling firewood, and the 2.5L
Chrysler 5 cylinder in my Plymouth Acclaim. However, my least durable
engine was also a 4 cylinder, the 1.8L engine in my 1984 Honda Accord
didn't even make 80,000 miles.

However, I've also had a Chrysler V-6 3.3L that went to nearly 180,000
before the vehicle was totaled.

I don't think there is anything inherent in the cylinder configuration
or number of cylinders that impacts durability. Reliability is,
however, better with fewer cylinders as there are simply fewer parts to
break and, part reliability being equal, fewer parts is always better.

Make certain you replace the timing belt at the specified interval (4
years/60k miles) on this engine. I have seen these belts fail shortly
outside the interval (either by time or mileage) and have even done a few
under warranty because they were still within the interval.

 

some of the cars in my family that lasted 150k miles......buick roadmaster,
plymouth cambridge, chevy II, lincoln continental, ford maverick, ford ltd,
lincoln versaille, plymouth scamp, dodge dart, amc ambassador, datsun 510,
datsun b210, opel manta rally, vw rabbit, vw golf, chevy caprice, dodge ram,
vw fox, toyota corolla, chevy sprint(suzuki), ford probe, buick
regal.......really, 150k is a pretty low bar to set.

 

I agree that 150K miles is nothing these days..let's see, I had a 93 Honda
Civic that went 297,000 and then broke the camshaft..it was getting soft and
burning oil by then though so it was on the way out, I gave it away to a
friend because I was sick of it after 9 years, it lives on with a new engine
and is well over 500,000 now. I had a Nissan minivan( I forget the year)
that I sold at around 200,000, an 86 Plymouth Turismo that went over
200,000, an old ford F350 diesel that I sold at around 250,000 , and so on.
Currently we have a 2002 Accent with 150,000, a 2001 F150 with 170,000, and
a Plymouth Sebring with ~150,000, all run just like new, with nothing
ridiculous having been changed on any of them except a blown rear end on the
F-150 at 75,000 , that annoyed me.

Oil changes are generally around 5000 miles for us, but I'm not a fanatic,
7000 happens too.

Yeah..my family drives too much, I know

 

my 2001 elantra was at 132,000 mile when I traded her in for a Sanata Fe.
it was still running like day 1 , getting 32+ miles to the gallon.
