Posted May 25, 201014 yr Hi, Looks like my Dragstars been filled up with final drive oil on the sidestand as when I checked upright it is about 3" lower than the filler hole !! Looks very new this oil--clear but does smell strong !! Question is I want to change it but the manual says SAE80 API GL-4 hypoid gear oil but can't get it anywhere !! Halfords say to use EP 80 but a web search says the EP 80 is acidic and not a direct replacement--attack yellow metal-brass copper etc. Don't know what to use now ? anybody used EP 80 Advice please. Graham.
May 26, 201014 yr Go to somewhere that sells the Silkolene stuff. Halfords ought to, as should almost everywhere else. Ask for BOA 80W-90. Their webshite says: "- SAE 80W, SAE 90 and SAE 85W-90 - API GL-4 or API GL-5 - MIL-L-2105B " If they really are idiots, there's pictures of it on the link here: http://www.silkolene.com/index.php?calling=product&sub=maintain#maintain_p18

Then went to local bike shop and there it was ! Sould have gone there in the first place of course, DOH ! Cheers, Graham.
