Just wanted to say hello and introduce myself. I'm creeping up on the 300,000-miles mark on my 2010 Equinox 4-cyl, but I see there are at least a few others here with even more mileage than that on their 2010-2012's! Impressive. Well, I'm looking forward to learning as I peruse the forums, and I hope I can contribute occasionally as well.

Are you the same guy on the Camping Forum who said he ate lunch with Bigfoot in the Cascades?

And as far as I know, there’s only one other person (on this forum, at least) who claims to have 300,000+ miles on a 2010 2.4L Equinox - but at least he detailed the laundry list of repairs he’d made to it (that read like a list of damages from a Demolition Derby, BTW). LOL!!

But *you* decide to pop in and say, “I just ate lunch with Bigfoot in the Cascades ...see ya ‘round...”. LOL!!

Sooo... give us some details:

- Cloyes is backordered on the timing chain sets. Did you do that?

- how many engine replacements?

- And did you (finally) do the “mod” where you put the V6’s 21-gallon gas tank in the lift gate area, fill it with oil, and pump it to your 2.4L engine to make sure it doesn’t run dry?

You not going to request a notarized photo of the odometer at every 100 miles ? Sheesh, you're getting easy in your old age.

No. I prefer a video showing the odometer changing at least 3 times.

LOL!

When I first started digging around the other day, I thought there was one person with a 2012 Equinox over 300, and someone with a 2010 Terrain closer to 400? I'll have to search again. But yeah, I saw the 2012 guy listed his work. I'll pull together the list I've kept and add it here. I also saw some questioning of whether his 300000 "counts" since it was mostly highway. Mine has not been all highway, as I can show from my speed history, so I'll be curious what people think.

Sooo... give us some details:

- Cloyes is backordered on the timing chain sets. Did you do that?
No bueno, I didn't know about the backorder. Replaced mine at 98777 and 184055, so I was planning to do it again now that I'm close to 300000.

- how many engine replacements?
None.

- And did you (finally) do the “mod” where you put the V6’s 21-gallon gas tank in the lift gate area, fill it with oil, and pump it to your 2.4L engine to make sure it doesn’t run dry?
I don't know what this means, so I guess the answer is no.

Like I said above, I'll pull together my service history and add it here later. I've only run into real oil consumption issues since I hit 250000 last year, but I've had those dang P0324 and 326 codes regularly since 170000.

LOL! I saw the forum gave that guy grief about his photos, so he posted video. Made me paranoid and now I'm planning to take video. But I don't plan to rev my engine to 4000 rpm!

I'm mostly kidding here. The Cloyes 'backorder' was a joke - implying that maybe you went through that many timing chains to get to 300k!

And the thing about the "mod" with the gas tank full of oil was like saying, "that's about the only way you could reliably keep this engine from running dry". LOL!

So you're gonna do the video? Great! I'll get my microwave popcorn ready ...

Ok, I did a quick search. @mgmsequinox broke 333k with his 2012 Equinox 4-cyl in June, and @alaric23 broke 400k with his 2010 Terrain V6 in December. It looks like @mgmsequinox does a lot of his own work...I can't claim the same. But here are my records nonetheless.

Driver's seat lumbar support bolt
ECM/PCM: Updated calibration for CEL P0324; updated oil life monitor; emissions recall
Spark plugs: 4x
Transmission fluid: 2x
Cleaned mass airflow sensor and throttle plate: 2x
High pressure fuel pump: 3x
Water pump
Timing chain: 2x
Cam shaft actuator VVT solenoid valves: 3x
Battery: 2x
Ignition coil
Spot weld between muffler and heat plate: 2x
Engine coolant flush
Throttle body replace
Broken shifter cable (transmission side)
Rear brakes: 2x
Oil pan gasket
Front struts
Rear shocks
Front axle shaft
Rear lower control arm
Alternator drive belt
One TPMS sensor
Ox sensor (bank 1 sensor 1)
Front brakes
Knock sensor
Front lowbeam lamps: I stopped counting
Rear lamps: 2x
Tires: 3x (70k tires lasted longer than that each time)

The first fuel pump and timing chain were done under warranty. I tried to get GM to cover the second timing chain under the 2013 letter given that it had been less than 90k since the previous replacement, but I didn't have any luck.

Oil change and tire rotation religiously every 5k. Regular oil, never made the switch to synthetic. After the oil consumption issue arose at 250k, I tried the Lucas Oil additive for the seals; seemed to help for the first 10k, but not after that.

I almost forgot, I promised some words on my city vs. highway driving. Here's a plot of hand-calculated MPG (actual miles divided by gallons added, as opposed to the onboard computer-calculated MPG) against the onboard computer calculated average speed -- all numbers reset and/or calculated at each gas tank fill-up. Using just the speed info, you can see I probably have an equal number of data points for stop-and-go roads <= 45 mph as I do for highways >= 45 mph. Lifetime average per tank of gas is 47.6 mph. Definitely leaning on the highway side, but also a lot of city miles included.

Wow. . good record for that 2.4L.


But wait. . no cracked exhaust manifolds? So many have had that here.

The scatter-plot of MPG vs avg speed is rather interesting. There doesn't seem to be any statistically significant trend taking place - which surprises me.

I must've missed the alaric23 post ... but then again - he had the V6, which is plausible. That engine appears to be solid. (now watch me snap a timing chain on my ride home tonight)

But you guys with that 2.4L engine going 300,000+ ... if this is real ... then maybe it wasn't bad rings, per-se, but how the rings ended up "seating"?? Maybe if everyone had run their 2.4L engines hard, racking up the miles fast and furious, it would've mitigated the Consumption issue?

Just a guess (or wishful thinking)...

Who would have known a direct injected 2.4 could run so long?

I unloaded my 2011, 2.4 after 5 years and 7,000 miles because of the horror stories relating to this engine, and the fact the high pressure pump was dumping raw fuel into the crankcase.

After discovering that the fuel pump had three revisions in around a years time, I decided I wanted this disaster gone. This engine was released before adequate testing had been done; so many marginal internal components that fail prematurely.

I still believe that the root cause of so many 2.4 problems stem from the engine oil contamination by fuel, and not necessarily because of faulty components like chains, actuators, pistons/rings, etc. Still the PCV system was poorly conceived and it alone causes many problems, including rear main engine seal failures.

In summary; I'm glad that I don't still have mine, but am intrigued that some of you have the fortitude to keep one of these running for so many miles! I'm impressed!

I know, right? I'd expected there to be a trend, but...nope.

Here are the other two scatter plots I've maintained over the vehicle life.

The first plot is the car-calculated MPG vs. my hand-calculated MPG per tank. As you can see, there is a statistically significant trend that the car calculation is too high.

The second plot is my hand-calculated MPG per tank vs. time. There was neither a point in the first 100k where MPG increased because the engine had been "broken in," nor a point in the last 100k when MPG decreased due to age or some specific lifetime wearing. For a vehicle that was supposed to be 22 mpg city / 32 mpg highway, and given that I trend towards highway, the lifetime mean of 24.7 mpg has been low and thus disappointing. However, on a positive note, even at 250k+ I can still get 32-35 mpg highway on some fill-ups.

@Colt Hero, don't grab your microwave popcorn just yet...since I can't post a video here, any suggestions where to post it?

In the meantime, here's a photo. And before you say anything, yes, I know, I COMPLETELY FAILED, it's not at the time of the rollover. I won't bore you with the list of reasons, because they're all weak. :sad:

Looking at that photo now...I need to dust off my console. Sheesh.

flickr? I think I've use that one before...

In the meantime, I recently/accidentally bought an extra box of popcorn (Pop Secret) in anticipation of my daughter visiting - so I'm sure I'll have plenty left even if your "Mileage Movie" doesn't premier until next year (I'm not a big popcorn fan)!

Are you planning anything dramatic for your movie - like maybe bombing down the local airport's runway with the speedometer pegged while taking the video?
