Hello,
All of your observations are a factor. Here are some comments from an
article about synthetic oil leaks:
Synthetic oil WILL NOT cause leaks. It may however make already worn-out
gaskets/seals more evident, by leaking past them, and/or cleaning any sludge
and other gunk that was sealing the existing leak. This is because Synthetic
oil has much better cleaning properties, flows much better than conventional
oil, and hence also lubricates much better than conventional oil (This is a
good thing).
I use a GL-4 synthetic gear oil in my transmission and it leaks. Believe it
not not one of the leak mechanisms is from the interior along the bolts and
drips from the bolt head on the exterior. I am changing the gaskets on my
transmission and trying bonded sealing neoprene washers on the fasteners.
I may be pursuing the impossible dream of a leak free Healey.... Harold

Subject: Does synthetic oil leak more?
I am not a leak expert, but I find this hard to understand. For there to be
a leak there has to be a hole. Is it because the synthetic oil molecules are
smaller than the non-synthetic oil molecules? Given that the "holes" come in
different sizes this seems illogical. Is it because the synthetic oil is
more slippery? How is that measured? How much more slippery is it?

The biggest difference you will notice with synthetic gear oils is they leak
more than non-synthetic.
