Sells for $40+ online
I am selling for $25 shipped free within continental USA
My RV dealer charges $300 for this oil change
Doing this myself i saved $225 per oil change
Oil change literally takes less than 15 min on my 40qt engine
I use 2 x 5gal bucket to collect the waste oil and drop it off at the
local auto shop where they recycle it.
I am planning on trading the coach in the near future so parting with aftermarket accessories
