The one time I thought I was burning oil I had forgotten to top off at the line after warm up! Next oil change I was freaking out!Francesca hasn't used a drop in all it's time. I worked with a mechanic who wouldn't believe that it didn't use a drop so I had him change the oil himself, he filled it perfectly to the line and marked down the K's then I brought it back to him at 5000K and he changed the oil and checked the level and sure enough, it was just as full as when he filled it up for me last time.
It didn't take the full 3.8L so I left the remainder with him so he would know I wasn't topping it up from the shop. I tend to do my own oil changes but I let him that time just to prove my point.
