My everyday car has an oil level system too - and no dipstick

Same with my present and previous cars, I gather the dipstick tube is
now relegated to a handy way of sucking the old oil out at service time,
even the oil filter is positioned at the top of the engine to avoid any
pesky bending down to reach it.

I can remotely monitor various readings from the car on my phone, it
seemed like the oil was drained within a minute of them starting to
service it ...
