Change interval is every 250,000 miles, or 36 months, whichever occurs first.

I purchased a small hand pump to add gear oil but I was able to pour it direct from the 1 qt bottle into the fill hole.
Vito, do you know which model drive axle you have?

Ok, I should remember what the 'H' at the end of your model # stands for, because I recently spent way to many hours on Dana/ Spicers web documents!

Mine is a 19060S, and I'm thinking that H (maybe helical gears), is the reason yours calls for synthetic gear oil.

My Coach also has the 22060SH. The "H" stands for High Performance. Whatever that means. The "S" is for Single Reduction.

I just changed it using conventional gear oil (Pennzoil 80W-90 GL-5) - so I hope your wrong about the synthetic being "required"). Maybe it is an option. I'll investigate further.

I have the service manual too, but there is nothing in it about lubrication requirements.
