Synthetic..........

[schaiken@e-chemicals.com]

I swear by Redline products:'59 Lotus 7S1 with a sprite running gear I use 50 wt
racing in the engine (1030 cc); Supershock Light in the rear and
transmission....................no signs of wear, quieter, cooler more
consistent oil temperatures...............as Myles points out  do change oil
regularly and do not use synthetic for break-in due to the poor release of metal
particles; When I have pulled axles and stand them in the corner the Supershock
light does not drip off.
