I have run WMO @ 90% WMO in a F-250 (6.0) & an old Mercedes 300TD for years.
There is a company that makes an EXCELLLENT centifuge for about $1500 that will remove all water & crap down to 1 Micron. The product is called "Simple centrifuge", and it works well.
I also installed a diesel performance products water seperator & filter system on my F-250. Makes a LOT more pressure, which is somethign to think about when running a more viscuous fluid.
