Benefit is unknown
Machinery needs maintenance. So, if the plans are to will the vehicle to great grandchildren, then some initial maintenance is smart.
And, as always, not everyone has the same commute, or vehicle reputation, or driving pattern, or weather conditions.
My 2.2 never had sludge with a 5000 mile oil change interval. My neighbor's same vehicle 2.2 sludged with a 5000 mile oil change interval. My driving patterns and oils used were different. If I did a 3k interval it wouldn't make a difference. If the neighbor used synthetic, he might've given the kids the car on their 16th birthday. He didn't use synthetic because it caused 'leaks' and wouldn't let the engine 'break in'.
Its not paranoia to maintain machinery. Its foolish to think that what you do will work for everyone. And, if they don't do what you do, then they are antienvironment, wasteful, and paranoid.
I guess its paranoia to brush ones teeth or take a shower. Do you wait until you smell like shtt for 50 yeards or until your teeth are akin to methmouth? Or do you shower daily and brush your teeth a couple times daily?
I keep cars forever.... a few recycled from accidents or stolen. But, I still have perfectly running 20 and 30 year vehicles. A blind person took out the 40 year old vehicle when it was parked on the street. All were running on original engines/transmissions. Can't say the same for any neighbors, relatives, or coworkers. So, its not paranoia.
Now, blindly believing all you read here concerning intervals based only on TBN or filter usage, based on marketing, is akin to a cult too. I see those that want to run oil until TBN is negative, and run oil filters forever... definitely suffer from marketing mental disease.
If you keep a vehicle long enough, plan on maintaining it. If you lease, trade in too often, or destroy vehicles, is there a point to maintenance? Minimal is fine for a bubblegum ownership pattern.
So, to answer the question, because the SANTAFE has the infamous theta-II, I would say its good. Maybe he will be lucky and not have the engine seize on MLK blvd during a protest when trying to commute to work to the ghetto hospital ER. This is why my wife's brand new Theta-II Kia had its 1st oil change at 700 miles. And, why I picked a synthetic over conventional, HTHS over MPG, synth media over OE filters, and a severe service interval over blind faith bazzillion mile interval. The car will last 10 years, it will be gifted to family, and it will have at least catalytic converters cut out in the next decade, and we will find it up on blocks or sitting on rotors in the employee hospital parking lot at least once in the next decade. Even the battery will be changed in year 4 regardless to make sure it always start during the escape from careerville.
Gotta run and visit great grandpa. He is in his 90's and smoked a pack of cigarettes and drank a 5th of cheap whiskey daily. So, the antismoking crowd are paranoid and AA meetings are a waste of time. That is what I think about when someone says don't maintain your vehicle/body because someone else got away with it. There isn't an automaker without engine problems or a dealership not waiting for engines or parts for engines. The owners manual is not the Bible. And, be wise and ignore marketing.
