I have a 95 Ford F250 PSD with a 17 quart capacity. This includes a 2qt. Motorcraft full flow filter and a 1-2qt. bypass filter filter installed. I used Shell Rotella T 15W40 for the first 40K, then installed the Amsoil and the bypass filter. I changed the bypass at 44K and had the oil analyized at 48K for a total of 8K on the oil. I added 3 qts. make-up oil at the bypass change, 10W30 HDD Amsoil, (I was out of the 15W40), this was for useage and filter change. These are the results:

All others were 0. This analysis was done by Oil Analyzers. I am using a dual foam air cleaner, diesel fuel additive, no oil additives. At 51K I dropped the oil and changed to Delo 400 after an engine flush with 3 bottles of Auto-Rx. I have 3.5K on the Delo and will sample at 6 months regardless of the mileage. I will change the FF and run another 6 months (1 Year total) and sample again, changing both FF and bypass, with both analysis being done by Dyson Analysis. I will change the oil when analysis dictates. I am not a fan of 3K oil changes when the capacity is 15 qts. and a $10 Motorcraft Fl-1995 full flow, thus the bypass filter.
The engine ran quite a bit quieter with the Amsoil than it does with dino. Power and mileage seem the same with either oil. This engine gets a workout in the hills when pulling my TT. GCVW is around 15K, and alot of 3200 rpm range driving. I limit my EGT to 1150 degrees pre-turbo and cool down to 270 degrees post-turbo for engine shutdown. I have two thermocouples and can switch between them. I also back off at 22 lbs. boost.
