My 300D had Petro Canada Duron 5W-40 in it when I purchased it. I used same oil for a few intervals. Oil leaks seemed to steadily get worse and I would consume quite a bit on highway trips(70-80 mph). I switched to Pennzoil 15W-40 and after about 1000 miles my three oil leaks have stopped and my consumption is barely noticeable after a highway trip. I think the PC oil is very good but it wants to get past my seals/rings. FYI.

Hmmm. I may not switch to it now. Thank you for you info.
Does anyone else have the same experience??
