im in the process of buying some ford diesels. im looking at one IDI for our company and a 7.3, or a 6.0 or 6.4 as my personal truck, havent decided which way im going to go yet. however id like to know as much as i can about IDIs both the 6.9 and the 7.3. what manuals back these engines? what automatics were offered? i know the 6.9s like to blow HGs and i know the 7.3s cavitate if the coolant additives arent up to *****. id like to know what oil these take, is it regular 15-40? can i use IH oil from the tractor dealership? i know these trucks are reliable and insanely cheap to fix. id like to know as much as i can. thanks in advance
