Cars age very very slowly here as the climate is very kind to cars. No winter freezing etc. I'll say one thing for Colombians with old cars or taxis, they generally are religeous about oil changes, it's part of the culture and at only 6000km or 3728 miles.
Gasoline engines can last 300 - 400k miles in taxis which also have huge idling hours on top. Colombians even close the doors with the minimal force possible to make the body last as long as possible.

Simply, products like high mileage oil are for Amercians who have abused and thrashed their vehicles, you would never find that for sale here.
When you are "rolling coal" enough to paint walls behind the car it's something bigger than a minor seal leak in which a fluid additive might help with.
