I use Valvoline Valplex EP Grease, only because I used to run Valvoline 2 stroke and I used to prefer it to the other brands so I guess I became brand loyal.
Any comments about the Valvoline?
It's a fine grease, used to be made in Australia, but now Valvoline import from the states.
Valplex EP, LMX, Marine Grease and PHD (Premium Heavy Duty) are the same grease (when Valplex EP was made in Australia).
All the Brand Name greases mentioned are fine greases, just make sure the grease has high temp properties and is either a Bentone or Lithium Complex. These greases give the better/best high temp properties over some Lithium greases.
HTB would be my recommendation followed by the LMX etc....
