a couple of questions:

I work with these sorts of filter deals on the hydraulic equipment at my plant.... so I am wondering a couple of things They usually have some sort of telltale on them that monitors filter back pressure to tell you when they need changing. Do these or do they just rely on you popping in a new filter every 10k miles or so?

1. What is the expected life of the filter (miles, hours, etc.)

2. It takes quite a while for a filter of that size to load up -- so what happens after about 1/2 of the expected life? Do they still filter as well after they run 10,000 miles as they do after 5,000 miles?

I guess that brings me to the request for long term info once you have run it a little longer. If you would not mind... once you have 3k to 5k on it, would you mind doing another oil analysis to see how it compares to when the filter is new?

Thanks
