Does driving a new car on long-distance highways have any impact?

[ElliottDella]

Driving a new car on long-distance highways 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 should not be driven on highways during the break-in period because high-speed engine operation can cause significant mechanical wear inside the engine. During the break-in period, the engine oil in a new car tends to contain more metal particles. Using this oil with a high concentration of particles for high-speed driving can increase engine wear and, in severe cases, may lead to irreversible damage, potentially preventing the vehicle from reaching optimal performance after the break-in period. It is recommended that car owners allow their new cars to go through a proper break-in period before extensive highway use. If highway driving is unavoidable, the vehicle's speed should be kept within a reasonable range, avoiding excessively high engine RPMs or speeds to prevent potential engine damage.
