I'd like to hear what maintenance neglect would cause pitted ,chipped valves?
I Think LSPI killed my Tucson tonight

Two things.
First, rude. This is BITOG. We are not here for feelings. We are here to get at the ultimate truth about motor oil. If a few feathers are ruffled along the way, that's even better.
Second, Ferrari. If this were a Ferrari, the issue would not be LSPI, or detonation, or improper oil, or slacking on maintenance. The issue would be oil consumption.
🤠
LOL I was thinking of excess intake-valve deposits, which could have been cleaned periodically.
Has not it been determined that Calcium is not associated with LSPI after all ?
I can see that. But is that part of a typical maintenance schedule? Does the owners manual specify to do this? Otherwise, its not neglected maintenance.
Always been my issue with Hyundai/Kia (& Ford to a lesser extent)-they seem to build vehicles that find, new, exciting, and EXPENSIVE ways to fail catastrophically!
One could argue that sure. I think it’s kinda silly that one would need to do that on a “run of the mill” grocery getter. It’s a great driving and looking car, but Hyundai needs to figure out how to make the car easier to maintain and that would include finding a solution on new models to reduce carbon buildup as Honda and Toyota have done, especially seeing they are now priced the same as their competitors.
Someone posted about the STP intake-valve cleaner here.

Note to self, don't buy a Hyundai.
Doesn't Hyundai/Kia have a 100,000-mile drivetrain warranty?
Oh, wait, the vehicle has 105,000 miles. Why do these things happen as soon as the warranty expires?

Yet some would say, where are all the cars with dead engines littering the road...
They are all towed and at the dealership waiting 6 months for an engine
Has it been determined if this is LSPI, pre-ignition knock or detonation? All three are different and have different causes. Two generally cause catastrophic damage.
I agree.
I'm running 91 on my DI 1.5 Honda and given the performance improvements with it, I couldn't bring myself to torture it with 87.
Were you running an API SP oil? Those oils are suppossed to have Low Speed Pre-ignition protection.
Please share what brand, model, and viscosity oil you were using.
If I had to make a wild guess, I would guess that that you had oil changed at a dealer or quick lube place. Both use the cheapest "no name bulk oil " they can find. Who knows what certifications those oils have.
I had taken one of my vehicles to the Honda dealer a while back for an oil change. The service advisor routed it to the Express Oil Lube part of the dealership. The guys were very young, and were not mechanics at all. All they do is oil changes. When I asked them if they were using Honda branded oil, they pointed to a long hose which went up to the ceiling which led to a bulk oil container with no visible writing on it and no viscosity indicated either. After they were done, I checked the oil and it was a quart low. I brought it back and they verified it was low and added a quart. Will never trust a dealer again for oil changes. To add insult to injury, they charged $60 for that oil change.

Sounds like none of the above, just a bad design 🤷♂️
M1 SP 5w30
Bad design, Valves that are prone to pitting (according to machinist) and as a result engine suffered spark knock due to ECU leaning out ratios (according to Indy mechanic). One valve in cylinder #2 had a chip.
Head is being redone with all new valves and is in the process of repair right now.
Pistons, bore, and all timing components still look brand new with very minimal wear and only light varnish. Engine has had M1 5w30 or VME 5w30 every 3k-4K max since I’ve owned it (bought at 24k miles). Before that it was a dealer serviced lease with 5-6k OCIs (QS semi-Syn 5w30 if I recall)
