Outstanding choice.   IMHO there's no better oil for an older vehicle 
for the money.   Period.


I used this oil when it was still branded as Kendall GT1 Race Oil in 
a musclecar that was abused and run HARD and the oil stood 
up.   Engine wear on things like the cam and lifters etc (with some 
serious valve springs) was never an issue, ever.  Likewise rod 
bearings that had to stand up to 7200 rpm blasts (more times than I'd 
wanna admit) in an engine with a 4.25" bore and a 3.75" stroke, 
moving a fairly heavy piston.  The rods weren't featherweights 
either...   The "green oil" worked.  It also would maintain decent 
oil pressure better than other oils when hot, such as after 50 miles 
at 70 mph, engine buzzing 3300 rpm the entire time.

Lots of people trusted that green oil, myself among them... including 
Isky Cams which recommended it by name, *on the packaging* for their 
camshafts used in performance engines.

My trouble now is that there's no close-by source for the Brad Penn 
oil.    Maybe someone local will carry it sooner or later.
