Oil Filter Replacement Tips at Downtown Chrysler

Your oil filter is the cleaner of your engine - it quietly cleans up dirt and metal bits so your motor doesn’t turn into a scrap heap. But this hardworking cleaner has an expiration date. Your engine could intake mud If you ignore it . Worse yet, you might not even realize it’s happening until your dashboard lights up or your car starts sounding like a washing machine. In this guide, our team at Downtown Chrysler breaks down the 5 unmistakable signs your oil filter is toast and why skipping a replacement could cost you thousands.

What is An Oil Filter & What Does it Do?

Every time your engine runs, oil flows through this filter, where a synthetic material screens out contaminants. Once the filter gets clogged, a bypass valve opens to keep oil flowing but it’s unfiltered. Skip replacing it, and you’re essentially letting your pistons and bearings marinate in gritty sludge.

5 Signs You Need to Replace Your Oil Filter

1. Unusual Exhaust Smoke

Blue or thick gray smoke from your exhaust often signals that oil is burning in the combustion chamber. While this can stem from worn piston or valve seals, a failing oil filter can accelerate these issues. A clogged filter forces dirty oil to circulate, increasing engine wear and allowing oil to leak into areas where it’s burned.

2. Strange Engine Noises

Knocking or ticking sounds from your engine are red flags. These noises occur when metal parts rub together due to inadequate lubrication. If your vehicle idles roughly or vibrates excessively at stops, it’s likely struggling with dirty oil.

3. Reduced Engine Performance

A bad oil filter forces your engine to work harder, increasing fuel consumption because dirty oil creates additional friction. If you’re visiting the gas station more frequently without changing driving habits, a failing filter could be the reason.

4. Oil Pressure or Check Engine Warning Lights On

If your dashboard’s oil pressure lights on, it’s a clear signal that oil isn’t flowing properly. Similarly, a check engine light paired with poor performance often points to oil-related issues.

5. Dark Oil

Clean oil is translucent and amber-coloured. If your dipstick reveals dark or gritty oil, the filter is no longer trapping dirt effectively.
