My father had a heart attack last night and I need to drive to Spokane- 1200 miles. I have 8000 miles on my amsoil 5 30 hd and filter. 500 miles over. Just found 2 gallons of new stuff in the basement and may be able to get a filter from dealer. I don't want to abuse my truck, any suggestions? I can't find a cummins shop open and the dealer doesn't have fleetguard blue. You can also email me at (all lower case) newman@dreamlinks .net Thanks guys. Dennis
