Anyone see API SQ?

I had an LSPI event within the 1st week of owning my new car. A 1.6T AWD Hyundai Kona and 17 PSI at 1,400+ rpm is the OEM tune. Felt like the jumped jumped 5 ft in the air and 3 second later my self talked "there goes a brand new motor" but after another 3 seconds of the shock starring at the tac, the car was idling normally. 72,000 miles later and stage 2 tuned, it still is running. Needles to say I now roll it on as habit at very low rpm. And it was very loud when it happened.

Hyundai… enough said. I’ve mentioned dozens of times that with knowledge of LSPI-inducing conditions, it’s a manufacturer’s defect to allow max-boost sub2k rpm conditions to exist. With automatic/CVT transmissions and electronic blowoff valves, these conditions are EASILY avoidable regardless of the oil used.

And it’s cool that your engine survived, but the LSPI events that everyone is being warned against destroy motors either by chunking a piston or snapping a rod like dry spaghetti.

Im on my 4th Navigator and all have that funky 440 horsepower, 3.5 liter direct injected twin turbo Ecoboost. One would think this is a prime candidate for it, but never seen it.

We've owned 8 Hyundai/KIA since 2008, some reaching over 150k miles, and one, a Theta II 2.0T reaching 350k miles. All using primarily 87 octane. Never a problem.

I haven't seen it yet. But, I haven't been looking for it.
I just learned about it in this forum post. It seems to address the newer lower viscosity oils and fuel mileage issues.
As long as it is equal to or better than SP, I'm okay with it.
