can an engine function properly after 100000mileage?

providing the oil change / service schedule has been kept to then a modern engine will be fine

as these days to sell a car in America, manufactureres have to show that a car will last 150,000 miles without major component replacement

so 100K miles should be fine

it may use more oil than when it was new and may not have quite as much power but it will be servicable
