[TR] oil pressure with synthetic oil

[Chip19474 at aol.com]

Jim,

Maybe you're seeing a combination of factors.......Mobil One is pretty good
 stuff (I use the 15W-50 in my TR6 with good results) and a little pricey
to  drain out without examining another possibility.  Assuming that your
engine  is reasonably "tight" and that you may have been using a
non-synthetic
20W-50 previously, is it possible that you're seeing the oil light
flickering because your oil pressure switch may be weak and is responding
inaccurately to a lower viscosity oil at idle?  If that idea doesn't play  out
and
you can't explain the flickering light any other way, then I would go  back
to
the previous oil selection (because it works well for you) and use the
Mobil One in your lawn tractor!

This  behavior started immediately with the new oil and it
isn't due to gas  collecting in the sump.
