Considering I had a massive oil leak and lost almost all my oil I think thats a pretty valid concern.

Anyway I read online that as its safe to mix synthetic/non-synthetic oils but mixing regular with synthetic will lower the quality of the synthetic. I know the dealer said if synthetic they use mobil one so I went ahead and got some of that and topped it off. The car was almost 1qt low. This is a day or two after having major work done at the dealer (replacing the upper oil pan and valves that go with it). I need to know if the car is burning oil like crazy (possible) or the dealer just f*cked up and put too little oil in (like a bit less than 5qt even though I have an oil cooler which means at least 5.5 qt).

I guess I will know in a few days...
