jthill3 Posted June 18, 2009 Share #1 Posted June 18, 2009 When running on the interstate at about 60mph, my oil pressure reads about 20 to 30 (about 25% of the gauge) but it drops to almost zero at the red light.This is not normal is it?Thanks for any help Link to comment Share on other sites More sharing options...
280~Master Posted June 19, 2009 Share #2 Posted June 19, 2009 I would check the sending unit on the passenger side to see if there is a leak or if its bad. Then do a check on the gauge to make sure its reading right. Check your oil level. I know my 76 oil pressure runs about 60 when running to 55-70. When the oil gets low the gauge sits lower like yours. Link to comment Share on other sites More sharing options...
jthill3 Posted June 19, 2009 Author Share #3 Posted June 19, 2009 Just a little more info - I did have the oil pressure checked at a shop not long ago and it was fine. I just never paid attention to the gauge really til yesterday.When the car starts, the Oil Pressure is about 45 to 50. But the gauge reads about 25 after I pull out of the driveway and goes to zero at a red light.I saw on some other boards where other folks have the similar experience. The general idea is that these Oil gauges aren't very good.....but I will check my oil pressure just to be sure...... Link to comment Share on other sites More sharing options...
Zedyone_kenobi Posted June 19, 2009 Share #4 Posted June 19, 2009 Buy a new sending unit. THey are relatively cheap and may help you out. MIne was nearing Zero with my original 37 year old gage. WHen I replaced it, I was reading about 20 psi at idle. THE sending units go bad after a while, its a common problem. Link to comment Share on other sites More sharing options...
