No, I am not using Pennzoil, and I have not yet changed the pump, I am considering it at this point.

It will do that every time. Do not use the high pressure one, could get oil behind bearings and spin one. Why did you decide to replace your oil pump anyway? -------Original Message------- From: Bob Jasinski <mailto:rpjasin@xxxxxxxxxxx> Date: 9/25/2011 2:48:28 PM To: chrysler300@xxxxxxxxxxxxxxx Subject: [Chrysler300] 413 oll pump I think it's time to replace the oil pump in my 300G. I'm noticing pressure is dropping to a very low level on a hot day after a long drive while in gear and idling (went to the Ironstone Concours in Murphys yesterday) I looked at Rock Auto, and they list 3 different oil pumps all from the same manufacturer (Sealed Power) and one is standard, the second is "High-Volume", the 3rd is "High Pressure". Prices are only $10 more as you go up. What gives? Why should I go with a standard pump if the other two are so close in price? Is there a problem going with a non-stock pump? Could it blow out seals in an older rebuilt engine? Those in the know please share your knowledge on this. Thanks!
