Regular oil changes are essential to keep your car running at peak performance. Clean oil lubricates the engine and its various components, which, in turn, prolongs the life span of the engine. But how do you know when it’s time for an oil change? The auto repair technicians at Mullanphy Tire & Automotive in Florissant, MO, list a few signs to watch out for.

Auto Repair Experts’ Guide to Oil Change Timing

1. Check Engine Light

If your check engine light is on, this is a tell-tale sign that there is too little oil in the engine and you need a change immediately. This light will go off when the engine is at risk of suffering damage due to lack of lubrication from oil.

2. Knocking or Rumbling Noises

Clean oil acts as a barrier between the engine parts to protect against friction. If the oil begins to break down, the various components will brush against one another and produce knocking or rumbling noises while you’re driving. It’s essential to get the oil changed right away, or it could cause significant damage.

3. Dirty Oil

Fresh car oil should be the color of amber, but over time, it can darken with the particles it picks up from the engine. It’s best to check the oil on a monthly basis to monitor when it changes color. Remove the dipstick from the engine, wipe it off, and then return it to the reservoir. Take it out a second time; if the dipstick cannot be seen through the oil, it’s time to have it changed by an auto repair technician.
