SomeB non-USA car brands (e.g. SAAB) did not initially require catalytic
converters and unleaded fuel.B Ditto for vans and trucks, even American
brands.B I had a 1982 Ford E-350 (bought used in 1986) that did not have the
converter or the restricted filler tube.B I could get only unleaded gas where
I lived then, which was northern New Jersey.B I was very surprised when I
moved to Denver, Colo., in 1990 that I could buy unleaded regular at the
Diamond Shamrock (now Valero).B B Of course, I have no idea if the heads were
"unleaded."B When I sold the van in 1999, it had some engine issues which may
or may not have been caused by using only unleaded gas except for theB 3-1/2
years I lived in Denver.

This last partv about USA laws is not true. B I bought a late-model 1977
Subaru (called a "Stage-II" because it was the 1978 body style) in the summer
of 1977. B Unlike many other cars of that time, it had no cat converter and no
restriction in the fuel filler neck to prevent the insertion of a leaded-fuel
filler hose. B It was labeled as meeting all USA (49-state) laws and allowing
the use of leaded gasoline. B Interestingly enough, the exhaust system did run
hotter than other non-cat cars. B I drove the car for 4 years, and put leaded
fuel in it the whole time, as I recall.
It was also the last brand-new car I have ever bought.
