Had anyone ever used Blendzall racing castor? Green label, gold label? I have a 98 gtx set up for premix... Always used it in my racing bikes. Love the smell... Any suggestions?
Personally I wouldn't waste the $$ expecting any performance improvement. Skis are much heavier that motorcycles and the hull is always the limiting factor. If you are racing where every little bit helps... it might help. Good Luck !
No, you don't want a castor oil in te cooler running watercraft and it isn't good for corrosion protection.
Your ski calls for any API-TC rated full synthetic.
Make sure you are still supplying oil to the rotary gear even if you are premix.
