I did it again, gave a nice description and left the link of the oil dispenser out. I edited my post above and here is the link http://www.northerntool.com/shop/tools/product_200623859_200623859 I am very pleased with it.
Here is a Northern Tool oil tank I have used for years that makes my oil changes much easier on the oil filling side of the job. http://www.northerntool.com/shop/tools/product_200623859_200623859 Just add some air pressure and the job is done with hands off. The location of the oil fill tube is made for a pressure fed system, not a gravity fed system. The tank was a reward to myself for doing the oil changes myself.
I had a 2000 ISB engine that I liked but after 12 years and 60,000 miles there were indications of excessive wear of the pistons, called piston slap. So I was forced to shop for a new MH or quit. I had planned to run the 2000 as long as I was RVing. The new RV has a 2012 ISB. It has more power and more fuel economy. I say I am better off with the new one, but of course not better off in the pocketbook. An older diesel will be running on the new low sulfur fuel which it was not designed for. Most everyone says it is not a problem. Why not buy a newer diesel while you are at it.
