| Post subject: | Oil pressure question |
When performing an oil pressure test on the CRD, is it common for the gauge reading to bounce around a lot? The gauge never read lower than spec, but bounced around more than normal with other cars. Is this just a normal quirk of the 2.8l diesel? |

Mine does not bounce. 17 psi steady at hot idle. Around 35 at 2000 rpm. Exact number escapes me right now. Rotella 5w-40 oil. |

I use the same oil. Thanks for the feedback. |

Are you using a mechanical gauge? Where are you tapping in? Mine is electrical, in the factory location, so that could be the difference. |

Yes, a mechanical dial gauge. I am reading at the oil sensor/sender port. Needle bounces around a lot, but never read low. |

You might have an air bubble in the gauge. |

Now I am thinking it is a bad oil filter. I'll change it and see what happens. |

I replaced the Napa Platinum filter with an OEM Mopar filter, and the oil pressure was much more stable. I guess I got a bad Napa filter. |
