Haven't you heard that a gas engine that hardly runs or runs for very short time is the worst way to kill a car ?
Not only is the super lightweight oil aging and breaking down from non use, but not running thru the engine creates sludge on the bottom of the oil pan; but the biggest enemy: water vapor condensation inside the engine for long periods of time is a corrosion killer from the inside.
That's the reason for the short "mileage" oil changes- the engine never gets hot enough to burn off the water condensation !
Similarly, my government work van that I drive daily (2,500 miles per YEAR) gets an oil change every year no matter how many miles.
OTOH, my other personal daily driver car which is a traditional ICE 4 cylinder 2L engine uses 0W20 oil and runs the same miles per day/month as the Clarity but does not need an oil change for at least 10,000 miles.
I can clearly see that not running the gas engine daily and with enough run time requires frequent oil changes....

Reason: compare ICE low miles
