Congratulations.

I've seen Rotella in Wally World, FWIW.  As for grade,
Scott Mockry's site has some info:

Sounds like something is shorting out, causing the circuit breaker
to trip.  I'd look to see if a wire under the seat is getting pinched
by something.

My first guess would be noisy lifters. Does the sound go away
after a minute or two?  If so, changing the oil and filter
will help.  Replacing the valve lifters will fix the problem
for another 100K miles.

> 4.  I've found conflicting info on the stock boost level and how much the ECU will allow, 

On the 10V 200s, it was 1.4 bar.  I think it's 1.8 bar on the
20V S cars.  I think on the 10Vs, even with a stiffer spring
giving greater boost, the display would max out at 1.4 and
you needed a chip to get it to display the actual value, but
I may be mis-remembering that.
