Its completely useless for the original posters application - Honda recommends API- SG rated engine oil with a viscosity of 10W30 or near for their manual gearboxes.
And Caltex's product works good - as it greatly resists shear when under the stress of meshing gears as it is also recommended for gear type pumps. the equivalent ZIC diesel/petrol rated oil will work nicely. but not the ZIC MTF being sold.
