When I used motor oil eventually by tightening the fitting, the drips would stop. With the synthetic oil the drips will not stop. Over the summer, while the car was sitting in the garage, there was a puddle in the plastic container I placed under the fitting before leaving for cooler weather. I just tightened the fitting a little more and the drips are reduced to 2 per day. Am thinking about using a thread sealant on the fitting and RTV on the gaskets.

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).<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:blue'>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.

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?
