I owned a 71' 145 with a B20B (SU's).  The engine was designed for 95
octane gasoline...tough to find.  Volvo published a note saying that
you should use leaded gas at least 30% of the time.  The lead
additives help lubricate the valve guides.  The mixture is not
critical.  You can burn two tanks of unleaded, then a tank of leaded.
They (Volvo) also have a set of head gaskets that lower the
compression ratio and allow you to use regular.  Check with your
local dealer.

I sold the 145 at 140,000 miles.  It's never been reworked.  I still
see it every day.  I now have a 82 turbo wagon (intercooled - kit)
which I love and hope to drive into the next century.
