Bonneville Nationals: 103.56 mph.
Yet a SAAB engine has only 3 cylinders
and takes oil in the gas tank. Strange

All cars that race at Bonneville have specially prepared engines. So did SAAB. Basically, though, the engine is the same. It is a 2-stroke engine with no valves and only 7 basic moving parts. That's hundreds fewer than conventional engines have; and hundreds fewer sources of friction, wear and potential trouble.

And because SAAB's 3-cylinder engine delivers a power stroke for every revolution, it is comparable to a 6-cylinder engine in torque, pickup and hill climb. But unlike a "6", it gets 28 to 38 mpg. It also grows old gracefully, with a minimum of maintenance. Strange powerplant. But very sensible.

With a SAAB, you put oil right in the gas tank (there is no crankcase). And no problem. The engine likes it that way because it continually receives a fresh bath of uncontaminated oil. There are fewer things to worry about: No oil pump. No oil filter. No clogged oil lines. No acids. No sludge. And, of course, no oil change. Strange powerplant? Ingenious powerplant! If you've never driven a car with a 2-stroke engine, see your SAAB dealer. And test-drive a 1964 SAAB. Only $1895, P.O.E. Shopping imports? Write for full descriptive literature on SAAB.
