JD, the Cummins 5.9 (?) is the best diesel engine of its size ever made period and I wish my truck had this rather than the Ford-but when you're choice is either a 6.0 or V10, is there really any choice to be made? Running a very close second, for its class, is the GM DMax, but for me I'll take ' six for sure everytime', old time leo's will understand that statement..... The GM is a work of art BUT why have eight when six gets the job done - better?
With regard to the Ford 6.0, the well documented 'failures' have mostly been head gaskets BUT the vast majority of those problems seem to have been self inflicted due to owners using performance chips, or rather this is the association I have seen reading posts. But, there have also been numerous issues reported by fleet operators, mostly ambulance companies.
I only know that the truck I use, an '07 with 78,000 miles on it runs flawlessly, uses not a drop of oil between its 5,000 changes-synthetic since 1,000 miles however it has no mods at all.
The best diesels we have had was the original 5 cyl MB used in the Sprinter vans and the numberous VW TDI's, all 1.9's-7 total.
BlackBart, yes the Company is Amsoil and I have gone from being the biggest critic (I always called it 'scamsoil') to one of the brands biggest promoters and I only use it for our own vehicles-and all our power equipment-I am not a dealer.
