My favorite Miller Lite:beer:...
As for synthetic oils, I've ran Mobil 1 in several engines including my 393W stroker. I've never had any bad experiences with the brand. But synthetic oil just has an odor. It doesn't varnish the internals. Even used some in an old Merry tiller that was using oil pretty good, lasted a lot longer than the conventional oil. Though I have swapped brand in my Mustang. The Autozone here in town only keeps the Castrol Syntec in 5W-20. Ford suggests servicing the 3 valve 4.6L every 4,500 miles and I stretch it out to an even 5K with this oil.
If your motor doesn't leak with conventional oil it shouldn't leak with synthetic. I believe this to be a myth. And I have never tried any of the blends. But I don't see why they would cause a leak either. The viscosity is the rated the same no matter what the origin of the oil.
