Grand Cherokee Problems
Jeep Grand Cherokee oil pressures problems are responsible for a significant string of symptoms. Others will will start immediately, only to have oil pressure drop suddenly, causing the motor to sputter and engine and oil gauges to light up. Oil pressure will likely drop when an engine starts to leak or burn oil. Most older Jeep Grand Cherokee engines (4.0L), call for 10W-30 oil for most driving and weather conditions. This is usually an acceptable oil, however, as Jeep Cherokee engines begin to wear, oil has the tendency of thinning considerably. Some Jeep Grand Cherokee drivers have attempted to remedy this common problem by using heavier oil. Heavier oil may fix the problem initially. Jeep Grand Cherokee oil pressure problems are commonly tackled with ongoing maintenance and recommended applications of oil treatments. Oil treatment helps oil retain its thickness and allows it to flow as it should.
Routine filter changes and oil pressure tests usually keep the engine running as smoothly as possible. Oil pumps on the Jeep Grand Cherokee are also known to fail in high mileage situations. The oil sending unit measures oil pressure and sends a signal to a sensor which engages the “Check Oil” or other gauge inside the Jeep. When oil loses it thickness and causes pressure disruptions the problem often results in a clogged galley, which runs to the oil sending unit. This can sometimes cause a difficulty in the sending unit reading the correct oil pressure. This blows the galley clear of obstructions and dirty oil consumption.
