well that is what i used last night when i put it back together i have some ppl say to use 75-90 and some say 75-140 is it going to hurt anything.......
I know you already changed it... but to be honest... I don't know if it would cause damage or not. It will take more power to turn it, and the thicker oil could cause a bearing to spin in the housing.... but I can't say I've ever heard of it actually happening.
