We were traveling on the interstate after about a 7 hour drive and the low oil pressure warning display was flickering on and off but never stayed on consistently. I pulled over and there was no oil in the engine, I mean it was bone dry. I'm truly surprised the car was still operating. When oil was put in, it poured, and I mean poured, right back out. We had to be towed because the car could not be driven. It was determined that the engine oil cooler line was leaking.
