Took mine to AUTOZONE, where they were most happy in receiving it and I didn't even buy the new oil from them.
Of all the work, I've ever done on any coach, this was probably one of the easiest. Greased it and changed the fuel filters, as well and all this without ever leaving the driveway and burning a drop of fuel. Done right and to my satisfaction, as well.
Next time will be for even more savings, as I now have the drain cart.
In essence, I got the cart, the filters, the pnematic grease gun and the oil for free, as a result of my labor, with money left over.
By the time, I do change the oil again, I might already be 80, so we'll see how it goes.
