[Healeys] synthetic oils

[Bob Spidell]

In aviation circles, mineral oil is known to do a better job of 
scavenging combustion byproducts.  It also degrades more gracefully than 
synthetic (though synthetic holds its characteristics longer).  There 
are no full-synthetic oils made today for piston-engined aircraft, but 
there are several semi-synthetics.

Something (else) to consider if your Healey doesn't have a particularly 
"tight" engine.
