First Hand Experience with LSPI Destroying Engine?

In reading about LSPI, there are a lot of references to potential engine damage. Does this happen outside of the testing laboratory? I am on a lot of boards (mostly Ford and Ecoboost) and haven't heard of any blown engines. Although there is a lot of talk about LSPI on Ecoboost engines. I am wondering if anyone on this board has first hand experience with this? If so, I would like to hear the story.
 
None that I have seen but there has to be lots if Manufacturers and oil blenders are making changes. A lot of it has to do with the poor fuel quality we have in North America.

Some of these are horrifying experiences.

Haven't read through all those forums, but aren't all those vehicles popular as being equipped with 4 cyl. turbo engines? Would that be the market this whole LSPI situation is addressing?
 
Hi DumC87 - For the most part, the issue concerns low displacement-direct injection-turbo applications. Most of which are 4cyl turbos but not exclusively.
 
[censored] engine design, poor driving skills and mods - this is why those engines fail. I’m 99.99% confident that oil is the least contributor to LSPI. Human stupidity - biggest
 
Here's another thread to look at...
http://www.subaruforester.org/vbulletin/...d-thread-570138

I have noticed that there does not seem to be much LSPI buzz around the bigger Ecoboost engines, the 2.7l and 3.5l units seen in trucks and luxury vehicles. I don't know if Ford has something special figured out or LSPI just tends to be an issue in the smaller displacement DITs (just noticed wemay had already mentioned this)...???
One would think something used for lots of towing would see plenty of low RPM, high load action.

Only 4 dyno runs in a row in this "out of the blue" failure. Stupid is as stupid does....F. Gump.

Took it to a dyno day, did 4 fantastic pulls. Made 240/302 on a mustang awd dyno. Drove it home normally in traffic and on the highway. Pulled into my driveway and it lost the cylinder. Deduced that it damaged the ring on the dyno (no clue why) and proceeded to eat itself alive on the way home. It literally gave no warning at all. Sent the data logs out to cobb and they confirmed that everything seemed normal while it was on the dyno.

Just curious, do the OEM's do similar or more aggressive WOT/testing on cars?

Just read that dexos1 Gen 2 and GF5+/6 have been cancelled because of this post, thanks for straightening the world out.

'

So the SAE releasing a paper talking about LSPI being able to be prevented largely by oil detergent package changes, and manufacturers making changes to their engine management computers is all because of drivers inability somehow?

Um, yeah... I would like to see some links on that to back it up.

Any engines with modifications, as in, most of the ones on that ST forum, have no relevance. Not Ford's fault when people have custom tunes and intakes and other garbage.

The stock ones are the concerning ones, but the type of oil used would be interesting to know. I suspect not all people use quality synthetics when they should.

I know that Hyundai changed something from the first Veloster turbos (2013) sometime around 2014-2014.5 model years. They changed some ECU tuning and spark plugs. I recently had to buy spark plugs for a 2015 Veloster turbo and went crazy trying to find out why different spark plugs were chosen for which years. I'm pretty sure after market tuners even noticed differences in the ECU tuning for that car (I think thats mentioned in one of the threads up above).

I know someone with a first year veloster turbo, who has been through 2 turbos and at one point the car was running horribly. turned out it somehow ate a spark plug. Not sure if related, or just first year issues.

So that kind of tells me it has quite a bit to do with engine tuning. As I've said before, My GTI (with DSG trans) will bog/lug the engine around in normal driving. Which I know isn't great for a turbo engine.

I think modern oils are reformulating to moving away from Moly and using perhaps something else unidentified because 2000+ Ca and Moly in the same formula seems to make an oil especially LPSI prone.
