I will say this .... I put ALL synthetics in Rosie, and now I know which gasgets need replaced !!!!

Exactly, Your gaskets were allready on their way out before you put the synthetics in. Leakage used to be a problem years ago when synthetics first came out, but no longer so. If your gaskets are in good shape, they are no more prone to leaking out with synthetics than with conventional fluids. Dave
