I have a 92' 400e, 102K miles, and the oil pressure gauge fluctuates like crazy... Previously (lower miles) it hung pretty steady a 3...except for idle, then down to between 1 and 2. Now it jumps all over, when the RPM changes... at hgwy speeds (3k RPM) it stays pretty steady at 3, but when in traffic it drops to 0 ... then when accelerating to about 2K rpm.. it will jump to 1 maybe 2 on the oil pressure gauge... then drop dramatically (to zero) when RMP drops below 2K or 1.5 K , way too erratic for me.. I am concerned that when i am slow traffic and the gauge is at zero, that the oil pump is truely at fault and i am causing harm, or is it possibly a faulty gauge, and the engine pump is actually fine, thereby false readings.... shoudl i be concerned about the oil pump?? thnaks..
