The culprit of this premature engine failure was a build up of oil sludge, most commonly caused by engine coolant leaking into the oil supply. Although a large percentage of these engines continue to suffer from problems related to oil sludge, there are some simple preventative steps that can be taken to make sure this doesn’t happen to your car. -------- Use high grade gasoline in your car. When you use a higher grade of petroleum, fewer impurities and pollutants enter your engine. Over time, this reduces the amount of carbon build up and other grime in your engine, which also reduces the likelihood of developing a problem with sludge. ---- Switch to synthetic motor oil. Synthetic oil is generally cleaner than traditional motor oil, and also serves as a better lubricant through some of the narrow passages in the engine. Being a cleaner oil means less grit and grime developing in the oil. Some of the higher quality oils, such as Castrol or Mobile One, will actually clean away old grime over time. --- Change your oil frequently. You should change your oil once every 3,000 miles, or ever 3 months, whichever comes first. Also change the oil filter at the same time. The manufacturer’s instructions may recommend oil changes at 5,000 or 6,000 miles, but this is really not adequate . Because the engine has a known history of sludge problems, you should take the initiative to change your oil more frequently. -------- Change your water pump and timing belt. If the belt fails, it will damage the water pump and cause a leak, or sometimes the pump just develops a leak on its own. This is the number one cause of engine sludge in the Intrepid. Do not wait until there is a problem to correct it. Preventative maintenance is key. You should replace your timing belt and water pump every 75,000 to 100,000 miles. ------- this will help.thanks.please do rate the solution.keep updated.thank you for using fixya.

We recently upgraded our oil so that we only have to change the oil every 5000 miles instead of 3000 miles. We are also now seeing on our odometer screen "Oil Pressure Low - Stop Engine Now". ...


I would not drive the car. I would have the oil pressure checked with a mechanical oil pressure gauge to verify that you really have an oil pressure problem. There is a possibility that the oil pressure sensor or wiring is bad causing the light to come on. Hope this helps :)

I have a 2006 maxima and the service light came on. I took it to a local shop and he put it through a diagnostic. Told me that the sensor in my transmission was showing error. Of course he reset it and it...


Have the sensor changed. When the vehicles computer senses an error in the transmission it puts the transmission in safe mode. Being that its a newer car you might check with your local nissan dealership and see if it is covered under warranty. Good luck:)
