greybeard 0 #1 Posted July 24, 2013 I have a wheel horse c-101 8 speed and I need to know what tranaxle oil to use. Someone told me I should use 85w-140. Is this correct? Share this post Link to post Share on other sites

gregg'shorses 77 #3 Posted July 25, 2013 Get an oil that is GL4 rated as GL5 has an additive that is hard on the bronze/brass components. Share this post Link to post Share on other sites

pfrederi 17,887 #5 Posted July 25, 2013 Get an oil that is GL4 rated as GL5 has an additive that is hard on the bronze/brass components. There are several GL5s that are now safe for yellow metals. The stuff WalMart sells is one of them Share this post Link to post Share on other sites
