i have a 1997 grand caravan with the v6 engine we've had a slow oil leak for a while know, put in about a quart every few weeks, but recently the oil light has begun comming on when the rpm's in the engine drop. it only does this when the engine is warm (say after
10-15 minutes of driving) then whenever the rpm's drop (slowing down, parking) the oil light will come on, and when the car is shifted back into park sometimes that shuts off the light. i have also noticed that accelerating also shuts off the oil light. I have dipped the engine and it seems to be over full (oil about 3 inches above the full mark on the dipstick.) is this car safe to drive? any ideas on what may be happening?puzzled
