Like mentioned, the normal tick tick tick n so on is the injectors. Been the norm for years. The BBQ tick is definitely noticeable and glad that I don't have it either.
Most of those oil treatments and such is snake oil. It's there for ppl to make money. Now Lucas isn't that bad but if you have no reason or an issue, don't use it just to use it. A good oil like motorcraft or better full synthetics will work perfectly fine.
