Hi Scotty,I have a 1990 Dodge w250 with a 5.9l v8 and when the oil is hot and I'm at a stop light or stop sign the pressure gauge drops completely but when I start moving the pressure gauge goes back to normal. Any ideas? using 10w-30 synthetic

Get the pressure checked with a hand held gauge to be sure - if it is low then you might want to swap out the oil pump to see if you can improve it - otherwise its just a natural sign of an old worn out engine
