Posted 4 years ago simondbarnesMember If I need 160ml of 10wt I can use 80ml of 15 and 80ml of 5 right? No. I did have the calculation you need to work it out but it’s years since I worked with oils and I can’t find it. Posted 4 years ago D0NKSubscriber Hmm did think i’d read that somewhere but while waiting for answers i did some googling, google likes stw http://singletrackworld.com/forum/topic/mixing-fork-oils Toy’s formula seems to stack up .66666666×7.5 + .33333333×15 = 10ish Actually thinking about it I’m in no rush for these forks and I need to order some other stuff might just order some 10 while I’m at it. Posted 4 years ago dannybgoodeSubscriber Remember – weight does not = viscosity so one mans 10wt may be thicker than another man’s 15wt. Plenty of threads on various forums kicking around on the issue. Cheers Danny B Posted 4 years ago D0NKSubscriber If I need 160ml of 10wt I can use 80ml of 15 and 80ml of 5 right?
