Dodge Stratus ES '96 oil pressure light comes on
Hi,
I have a Dodge Stratus ES '96 with 130K miles on it. Lately the oil pressure light has come on. I just changed oil (10W-30) and the oil level is full (not too full though). The light only comes on after the engine is warm and it is running on idle. As soon as I step on the gas pedal the light turnes off. (The idle speed is about 750rpm). It seems like the engine speed when the light goes off is variable, maybe related to how warm the engine is? Sometimes when I stop at a stop light, it is enough to just put the transmission in neutral (increasing the engine rpm to 750) to get the light to turn off. Any ideas? Thanks, Olav |

If it is leaking replace it. If not, have someone manually test your oil pressure with an external gauge, if the pressure is ok, replace the sending unit Glenn Beasley Chrysler Tech |

I would you recommend to use 15W-40 for a motor with this miles.
If the problem reoccurs, how about oil filter or then check oil pump. Regards, Ralf -- www.omnibusclub.de |

When the switch gets marginal like that, small changes in idle speed can mean the difference between a closed or open pressure switch (lit and unlit dash light) due to minor fluctuations in oil pressure.

Thanks for your answer. Why does this happen only when the engine is
warm? Also, does anyone know what the "idle" speed should be when the transmission is in "drive" and the car is still? Mine decreases to almost 500rpm. Thanks again, Olav |

Replace the PCV valve. I had exact same problem and it cured mine. I
theorized that my engine (2.5L) was running a little rough at idle - just enough to lower the rpm's so that oil pump wasn't pumping enough pressure. I replaced the PCV valve and the idle smoothed out and the light hasn't come on for last 9,000 kms. > wrote in message oups.com... > Hi, > > I have a Dodge Stratus ES '96 with 130K miles on it.
