<DIV dir=ltr align=left>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).</DIV>

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.</FONT></SPAN></DIV>

<DIV style="COLOR: black; FONT: 10pt arial">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?
