Wow... I've never heard such stories about Castrol. Up until the advent 
of synthetics, I ran Castrol 20W-50 in everything I owned (British, 
Corvairs, other American , etc) that needed a heavy oil. While it would 
indeed thin badly after being overheated (or heated for a long period of 
time, like track use), it held up better than any other multiple 
viscosity oil I had used. (I had never tried Kendall). This is still the 
only Dino oil I use and is still the #1 recommended oil by most European 
car owners.

Now I _am_ a bit younger than you guys... I didn't start using it until 
the early 80's... and was not "abusing" it until the late 80's.... so 
possibly the formulation was different?
