Does Driving a New Car on the Highway Have Any Impact?

[OEmery]

Driving a new car on the highway does have some impact, but the effect is minimal and will not affect the normal use of the vehicle. Many car owners believe that new cars in the break-in period should not be driven on the highway because high-speed operation of the engine can cause significant mechanical wear inside the engine. The engine oil in a new car tends to contain more metal particles, and using this oil with a high amount of debris for highway driving can increase engine wear. In severe cases, it may lead to irreversible damage, potentially preventing the vehicle from reaching its optimal performance after the break-in period. It is recommended that owners allow their new cars to go through a proper break-in period after purchase. If highway driving is necessary, the vehicle's speed should be kept within a reasonable range, avoiding excessively high RPMs or speeds to prevent engine damage.
