Help: my car is leaking oil
my car has been leeking oil for about two months now. I did an oil change about three weeks to mobil 1 synthetic oil. My car is still leaking oil:/ it usually only leaks oil at cold starts meaning almost every morning. It is leaking oil by the oil pan. I will post a couple of pictures in a bit since I'm on my iPhone. Any ideas why it's leaking? And how much it'll be to repair it?

Mine is leaking from the oil pan bolt. I've been lazy lately. Instead of removing the entire underbody plastic cover. I just remove a few bolts and bend the plastic back far enough for me to reach the oil pan and filter.
This doesn't give me enough leverage to fully tighten the bolt. So I do see a few drips near the bolt. Since it's a crush washer, if you don't tighten it right, it becomes loose over time.

Begin by checking the dip stick, is it seated? Is your crush washer leaking and also check the oil filter, it should be hand tight plus 1/4 turn. What it will cost you depends on where the leak is, the crush washer might not cost you anything if they're cool. If it's something like valve cover gaskets it will cost consideralby more. Stay away from Infiniti, take your G to Nissan and the cost will be less regardless of the issue your having!

I have the exact same issue after changing from regular oil to MOBIL 1 synthetic. I did replace the copper washer on the drain plug at that time, but I think the leak may be from the oil pan itself. Is this due to the oil being synthetic, if so would changing back to regular oil stop the leak?

This is probably the culprit. It is the gasket on the oil cooler that the filter screws into. If it's tightened too much it will fail and cause a leak from around the oil filter. Easy to replace, pick one up at the Nissan dealership and DIY.
