Your Toyota 4Runner uses an oil filter for a good reason. That's because it needs the filter to strain out contaminants that are present in the motor oil, whether they're left over following the refining process or collected while the oil lubricates your engine.

How to Spot Faulty Oil Filters

Eventually, though, even the best oil filter will either get too clogged up with particulates to work properly, or it will degrade with age. When that happens, the pollutants in the oil can accumulate inside your engine and begin to cause problems. Signs of trouble include:

Your engine starts sputtering

Worsening engine performance

Dirty smoke coming out of your exhaust pipe

You hear metallic noises coming from the engine

A dashboard warning light comes on
