[TR] oil pressure with synthetic oil

[Jim Muller]

I know this has been discussed before, but what the heck, if it was 
interesting once it might be interesting again.

Several weeks ago I changed the oil in the GT6, put in Mobil-1 15w50 
I think it was.  I had used it prior to this oil change, something 
labelled "extended life" or similar, but this wasn't labelled like 
that.  It used to be that with thin oil I'd hear valve clatter, but I 
don't hear that at the moment.  What I am getting though is the oil 
pressure light (and brake light) flickering when at idle after I've 
been on the highway for a while.  Given a chance for the oil to cool 
the flickering goes away again.  The temp gauge is acting quite 
normal.  This behavior started immediately with the new oil and it 
isn't due to gas collecting in the sump.

It is somewhat disconcerting and I'm tempted to drain it.

Comments welcome.
