Automotive experts have issued guidance regarding essential vehicle maintenance and refueling practices to prevent engine and fuel system damage.

Mechanics advise against following excessively long oil change intervals, such as 30,000 kilometers, noting that fuel dilution during particulate filter regeneration can reduce oil protection. Instead, more frequent changes every 10,000 kilometers are recommended for modern gasoline engines, alongside strict adherence to manufacturer specifications.

Regarding fuel management, experts warn against overfilling tanks after the automatic pump nozzle clicks off. Doing so can occupy the expansion space required for fuel vapors, potentially leading to leaks or damage to the evaporative emission control system as fuel expands due to heat.
