I currently have 3ea 3 cylinger Fords....3000, 3600, and 3910. I use them a few hundred hours a year. I get mixed emotions about HD antifreeze (Fleetguard from my OTR truck dealer for one) designed to prevent pitting of cylinder liners in particular and I have been told by Ford mechanics that even non-sleeved line bored blocks in these tractors "can" have cavitation problems.
So I look up the specs on current Prestone and it lists its approved for light duty diesels....light duty.
Ok, Fleetguard is recommended for OTR HD diesel engines, a lot of which run 500,000 miles before overhaul and doing it in a few years pulling 80,000 loads all day and all night..........daaaaaa Is there something that I'm missing here?
