I have a 1996 Prevost bus/motorhome. It weighs 41k to 51k#s going down the road (65mph) depending upon what we're towing or not. Gross combined vehicle rating is 57k#s.
In June of 2014, when it had 67k miles, I changed the rear differential gear oil with 4.5 gals of Amsoil SVG 75w-90. Today it has 112k miles. I'm changing the gear oil again soon and want to know who best to send a sample to for analysis?
It's a Rockwell Intl 3 member, model A58 3200P1706, ratio 4.56
