As soon as I started my MDX during the freeze I felt something was wrong how car started. I checked underneath and saw oil leaking. I stopped the engine but saw all the oil on the driveway. It was empty when I checked with dipstick. So next morning I examined and saw lot of oil around the filter area. So i cleaned up everything and replaced the filter and put 4 quarts of oil. I waited for 15 mins to see if any oil is leaking. Now I start the vehicle then oil starts to leak dripping somewhere higher than oil filter. I am not sure where the oil is leaking from. I would like to further troubleshoot before taking the vehicle to the shop. Any feedback is appreciated.
