It's always recommended to use spark plugs listed in owner's manuals. To use other than factory spark plugs makes you the Beta tester requiring knowledge of plug type, heat range, plug gap setting, etc. If you are using OEM spark plugs and wear or fouling occurs then this isn't a plug issue. Although most vehicles require less maintenance, replacing spark plugs, cleaning throttle bodies, replacing air and oil filters are still maintenance chores either a diyer performs or pays a dealer or repair shop to perform. Owner's manuals always suggest maintenance intervals to ensure optimum performance from our vehicles. Ignoring or forgetting maintenance introduces problems either sneaking up slowly or immediately. Servicing also allows one to see if any unusual wear occurs like a ruptured rubber hose or leaking fluid.
Using your car only once or twice a week would be considered light duty use, not anywhere near moderate use like daily driving. Severe use would be Ubering or delivering pizzas/fast food daily.
