Hello FTE forum, was hoping to find information about the F250HD 7.3L turbo diesel engine supplement as mentioned in the owners manual. I picked up an all white '97 creampuff w 77K miles. All original body and paint. Super Cab 2wd with the ZF 5 speed. Owners manual packet is there but not the diesel supplement. I need to educate myself on the engine capacities and change intervals. I have been to Ford online and 800 cust service with no luck. I'm new to the truck scene and FTE seems to be the place for info gathering etc... Thanks in advance.
