So My 4runner leaking with Synthetic and My Land Rover leaking with synthetic are just total bullsh!t then? They dont leak on non synthetic.
I know why it leaks, the cars had alot of miles with conventional oil which was thick enough to fill up any small holes that leak, the sythetic broke down that old oil at the seals and caused minor leaks. I find it easier to run non synthetic, in these vehicles, the jetta on the other hand looks brand new at 260+ k miles with all synthetic.
Your seals are bad which if you have run synthetic from the beginning probably would not be happening. if you are telling me that you basically are relying on engine sludge to keep the oil in your car then synthetic is the least of your problems.
Bad seals are bad seals, so if a tiny thin film of harden sludge is what is keeping everything from leaking then I have to question why would anyone ever use petroleum based oil if it does that to the engine.
