Should you prime the oil filter before installation when changing the engine oil filter?

Priming the oil filter before installation is generally considered a good practice in engine maintenance. When you fill the new filter with oil prior to installation, it helps to ensure that the engine receives oil more quickly upon startup. This is particularly important because engines rely on a proper supply of lubrication to prevent wear and tear, especially during the critical moments right after the engine is started.

When a new filter is installed dry, it may take a moment for the oil to fill the filter and reach the engine, which can lead to increased friction and potential damage. Priming effectively reduces this risk, allowing the filtration process to begin immediately as the engine starts.

While some manufacturers might have specifications regarding this practice or recommend against it based on their specific filter designs, priming has become a widely accepted procedure in automotive maintenance aimed at improving reliability and engine longevity.
