They don’t. They design, manufacture, and sell a vehicles which will go three years, or the period that they provide a warranty on it, and a bit beyond. The manufacturers don’t want vehicles to last years and mega mileage. They want to sell you another vehicle. It’s the same thing with non service gearbox and the like, where a new industries has been developed to keep these vehicles going. Otherwise thousands of vehicles would be being scrapped, or required costly components. The further apart their service the more appealing it is to the buyer. It’s not the best for the engine, or other parts. If it says 28000 that is its maximum, not its best. All you are doing is wasting a small amount of money (in relative terms) to prolong the life of the vehicle, by changing the oil earlier.
I have a 20 year old car, and a 13 year old car. They haven't died yet. They are on 74000 and 85000. The 85000 one's miles have mostly been very hare driven ones with many on track. Apart from my motorhome I have never had a car less than 3 years old when I bought it. I really don't think they are designed to fail after 3 years!!! You have bought into the mentality that you have to keep changing cars every 2/3 years. It's not necessary.
As for motorhomes. Most only do 5000 a year max - lots do much less. They are never likely to get to 100,000 miles with he first owner. Not for 30 years at least.
Suspension items, bushes, joints, exhaust, brakes, etc etc are more of a concern for reliability/longevity than a bit of oil in the engine.
