The oil filter is something of an unsung hero under your hood. By continually collecting harmful particles, the filter prevents the motor oil from thickening into sludge, thereby keeping your engine from harm. As time passes, oil filters become overloaded with collected contaminants and need to be replaced. Here are six clear signs you should visit your local Isuzu dealer for a new oil filter without delay.
Your Motor Oil Looks Dark and Gritty
You can visually inspect your motor oil at any time to check its level and condition. When fresh, motor oil is transparent, clean, and the color of amber. If your oil appears dark, grimy, filled with particles, and sludgy, it’s time to flush and refresh it.
Your Oil Pressure Plummets
A clogged-up filter will restrict the flow of oil through the engine and cause the pressure to drop. If this happens, you’ll see the oil pressure warning light appear on your dashboard. Ask a trusted technician to check the oil and filter at once.
Your Filter Is Leaking Oil
Falling oil pressure might also indicate an oil leak, which could originate from an improper seal around the oil filter adapter. If you suspect a leak, check under your car for dripping oil. Leaking oil might be caused by a problematic filter or another fault; it’s best to ask a professional to take a look.
Your Engine Loses Power
When a clogged filter prevents the oil from circulating properly or allows contaminants to degrade the oil, the engine will struggle to operate at full capacity. This results in a drop in engine power.
You See Smoke in the Exhaust Fumes
If a bad filter impacts the oil pressure, it can force some oil to squeeze past the piston rings into the cylinder. The oil will then contaminate the combustion process, causing black smoke to escape through the exhaust system.
Your Engine Emits Knocking Noises
Motor oil must lubricate the engine’s many moving parts. If a clogged-up filter prevents the oil from doing its job, friction will rise between the components, generating knocking and ticking sounds. These noises indicate potentially serious damage occurring to the engine and should never be ignored.
Routinely Visit Your Isuzu Dealer To Replace Your Filter
A sensible rule of thumb for most drivers is to replace their oil filter every second oil change, which typically means once per year. However, some drivers need a new filter every six months. You can consult with one of our technicians to figure out the optimal schedule for your vehicle. Regular oil changes are key to a healthy engine. During each oil change, our technicians can inspect your filter and replace it as required. Visit Conley Isuzu Truck Center in Bradenton, FL today to have your oil and filter serviced.
