I have been using the GC for my 90 300ZX w/55K miles on it. Going to change oile again in next few days.
Dropped by to see whats up and found that lot of people talking about the new Platinum Penz.
Just curious if any of the GC users have tried it and what they thought of it.
I dont have enough GC so I need to either buy some more GC or buy something else and try it.
thanks
Mike
