I have to agree with you.
here is a quick search I did on mobil1 .com. I tend to stick with what engineers say.

Question:
How to Handle 20,000-Mile Motor Oil Drain Intervals When a Car is Driven Infrequently
Porsche recommends an extremely long drain interval of 20,000 miles for Mobil 1--which is great but since my 2006 911 is a "weekend car" it only gets 5-6,000 miles per year. Should I wait to change the oil at 20,000 miles or should I change it when 2 or 3 years are up?
-- Roy James, Phoenix, AZ
Answer:
We recommend following the drain intervals listed in your owner's manual. Mobil 1 would satisfy those longer drain intervals as long as the manufacturer makes that suggestion.
To achieve the best peace of mind related to engine protection, many vehicle owners change their engine oils every 3,000 to 4,000 miles. Is this practice rendered meaningless with the advent of the Mobil high-endurance oils?
Consumers should follow the maintenance practice that is best for them, and that meets their car manufacturers’ warranty. They can have peace of mind knowing the guaranteed performance and protection intervals of the Mobil line of high-endurance oils. Mobil Clean 5000, Mobil Clean High Mileage, Mobil Clean 7500, and Mobil 1 Extended Performance protect critical engine parts from lubricant-related failure for 5,000/7,500/15,000 miles -- guaranteed.
