Have you had good luck avoiding oil leaks?

Some people say if you get them to go to slightly higher viscosity like 0-30w to 5 -40w and supposedly Liqui Moly might condition rubber seals better.

I just bought 2018 X5 with N55. The SUV is in like new shape with about 39.5K miles. I am paranoid of getting oil leaks. The other issue people talk about is the water pump can fail at any time. The car will supposedly warn you to shut down immediately.

My wife has a 2014 320i and has had very few problems. A B48 with about 74K miles.

I hope you held onto one of those 2002's. I wanted to get one in high school back in the day - about when Bob Lutz launched the 2002 turbo.

Thanks.
