Most people associate L O T U S with Lots Of Trouble Usually Serious.
Here is another one:-
Leaks Oil Through Unreachable Seals.
There are two schools of thought about the actual origin.
1) Once you have tasted the Lotus seed, you don't want anything else. Peel away the bitter pith and what remains is a mild, white, slightly sweet seed with a taste between pine nuts and green almonds, packed with protein. And if you've only ever come across the flavour of lotus seed as a bland paste filling a mooncake, trying the real thing is a must. Therefore once you have driven a Lotus you don't want to drive anything else.
2) Chapman sent a car to auction, and it came back Lot U/S, (Lot unsold), and he thought that is a good name for a brand of car.
I think oil leaks are just something you have to put up with, and check the levels regularly.
