[Supras] finally ready to fix my BHG and drive the Supra again . . . a few questions

[Kevin Bohrer]

Most of you all probably don't remember me, but I've been on the list
since '99.  I haven't posted much, because my poor car has been sitting
idle while I'm busy raising kids, remodeling my house, etc.  I might
finally have a chance this weekend to start in on the long list of items
my car needs.  

A quick history & plan: it's an '89 turbo 5 sp.  First & foremost is a
blown headgasket.  I'm putting a new stock gasket & new stock bolts back
in, with future plans for modest HP mods (<300).  I have to helicoil the
exhaust studs, fix my knock sensor wire, fix a coolant leak, fix my vsv,
put on HKS turbo cat back, get a new downpipe & cat, etc. etc.  I plan
to get the head off this weekend & take it from there.

I'll try not to ask too many stupid questions, but I appreciate in
advance all the help I know I'll get!  My first question is about the
gasoline.  I last filled up the tank almost 2 years ago.  I put in
Sta-bil, 92 octane.  Is there any chance this gas is still OK to run?  I
know it loses octane over time, but I know our cars can run on 87 (at
least when the knock sensor is working!).  I'm hoping it will be OK to
at least get it running & a slow cruise.  If it runs good, I may empty
the tank & get fresh gas, but I'd rather not unless you guys (& gals)
think I need to drain it first.

Thanks in advance . . . I'm diving in!
