The manual calls for the same stuff as an XR which I've been using without any problems for years. Same oil for the fuel pump too.
Now I have SCX's and they call for Torco RTF GL6. Can I use the Torco in the blowers and pumps? I don't see why I couldn't other than maybe a fuel compatibility problem.

They are all in the same class of lubricant, the GL"xx" references additives and levels of protection, higher mainly being better "For the enthusiast wanting maximum protection, it is my opinion that the additional protection that is offered by a “GL-6” rated product is a worthwhile investment.
