I just had my oil cooler lines recently replaced..and do not recall if I was having this problem beforehand. My oil pressure gauge at start-up is at around 35, and increases to about 40 when driving. Now here is the problem in question, when I'm on the Highway if I'm doing around 70mph and punch down on the gas pedal the oil pressure gauge will shoot up to about 65 and drop back down. Is this normal when punching down on gas?
