The jeep wrangler features an oil life indicator system that notifies when the oil in the engine is too low and needs a change. Even after an oil change, the indicator system does not reset and stops the notification automatically. You need to reset the oil life manually after every oil change.
You can reset the oil life on the Jeep wrangler by turning the ignition on the ON/RUN position. Press the accelerator thrice within ten seconds and then turn on the LOCK position. You can also push the oil life reset button which will reset it to 100%.
We have accumulated all the necessary information about the oil life and the indicator system of a jeep wrangler for your convenience. We will let you know the procedure for resetting the oil life on your Jeep wrangler.
What Are The Signs That You Need an Oil Life reset?
The oil life indicator system turns on a blinking maintenance light to indicate that the oil needs a change. Consequently, the oil life also needs to be reset afterwards. There can be a few clear signs that will indicate you need an oil life reset:
1. Oil Life Maintenance Light Is On
One of the most obvious signs of needing an oil life reset is the illuminated maintenance light. Jeep wrangler system is designed by the manufacturer as such so that the oil maintenance light comes on after a specific mileage.
When the oil level drops too low for the system, this light comes on. Change the oil and then reset the oil life once you get this light.
2. Increased Engine Noise and Knocking
Engine oil flows inside the engine and keeps the metal bodies from getting in contact with each other too much. Lack of enough engine oil does not provide the necessary lubrication in the engine parts.
So, the moving components of the engine grind against each other and make excessive noise.
If you notice sudden loud noises from your usually quiet engine, it is a sign that you need an oil life reset. The occurrence of knocking increases as a symptom too.
3. Dirty Engine Oil
You can only notice this sign if you have a habit of checking up the engine periodically. The clean oil gets dirty and dark due to the accumulation of particles inside the engine.
Fresh, clear amber colored oil turns black and has a thick consistency. But the dirty oil clogs up the engine and performs very poorly. So you can take it as a clear sign to reset the oil life and change the engine oil with a new, clean one.
4. Emission Of Exhaust Smoke
Another sign of an oil life reset necessity is watching exhaust smoke coming out of the pipes. Usually, this black exhaust smoke means oil leaks or insufficient oil in the engine. Therefore, an oil change and oil life reset can fix this up right away.
5. Excessive Mileage
It is recommended to change the oil and reset the oil life every 3000 miles. By checking the odometer, if you notice that the jeep has traveled a lot of miles since the last oil life reset, it should be a sign. The odometer will show you the amount of extra mileage so that you can take initiative and reset the oil life immediately.

What happens if you don’t reset Jeep Wrangler oil life?
You might ask what is such a big deal about simply resetting a harmless oil life. Well, let me tell you from my own experience about the issues the engine of your jeep wrangler will face.
If you don’t reset the Jeep Wrangler oil life, the results will not be instantaneous, rather it will affect the engine over time. Here is what will happen if you don’t reset Jeep wrangler oil life:
1. Increased Oil Viscosity
The oil inside the engine encounters oxygen, heat and pressure. Due to these, the oil gets oxidized as it is used. As the oxidation of oil increases, so does the viscosity rating of the oil. Not resetting the oil life on time will lead to increased oil viscosity rating.
If the viscosity reaches too high, the oil will not have proper flow within the engine. It will not perform properly and cause damage.
2. Loss of Efficiency
Due to dirty oil with an increased amount of viscosity, the engine starts having trouble in putting up its best performance. The efficiency of the engine gets reduced by a long shot.
Therefore, the engine has a higher chance of becoming less efficient as time goes by without resetting the oil life.
3. High Risk Of A Mechanical Failure
The lack of proper leveled and clean oil prevents the smooth oil flow and mechanisms inside the engine. As a result, there can be a myriad of mechanical failures at any components inside the engine.
The engines lose proper lubrication and grind against each other. This additional stress causes wear and tear on the mechanical parts. The mechanical failures due to this can range anywhere between a seized engine, blown gasket to a complete engine failure.
