Nissan Frontier engine whine noise possibly caused by cheap oil filter on Nissan Frontier

Some Nissan Frontier owners report experiencing a whining noise in the engine that changes pitch with engine speed, which may be linked to the use of cheap or non-Nissan oil filters. This issue can arise due to a defective or improperly manufactured bypass valve in the oil filter, underscoring the importance of using high-quality filters. Additionally, some owners find that low or dirty engine oil contributes to this noise, making it crucial to regularly check oil levels and quality, and to replace it with the recommended oil as needed. Promptly addressing these concerns can help mitigate engine whine noises in the Nissan Frontier.
