I watched a video on Wired to Fish about changing hub oil on a Ranger. Even though I have no problem doing this on my Ranger I watched the video anyway. I noticed that he used "Lucas Hub Oil" I then emailed Lucas to inquire as to what the weight of their hub oil was. They responded by telling me that it was around 250 Wt!! and designed for Big Rigs. Has anyone ever used this product on their Ranger Hubs?
