New engine noise

I always thought timing chain noise was more arrhythmic than that video. That sounds potentially more like a piston, valve, or lifter issue.

I’ll be honest when I was broke/unemployed right after Covid hit I ran a bunch of 87 octane through my LR4. Never had issues. Could never tell the difference between 87 and 91.

I have always run top tier fuel though, usually from Costco.
