bassicly up until may the truck was under warranty so i wasnt able to do anything to it without killing that so in truth the truck has 15k on it of me trying to solve problems. so selling it isnt a huge deal to me yet. its been studded and the egr is gone. injectors are brand new so really the only things that i can see being problems anymore r the hpop and the transmission.

The Rotella T5 10w 30 is what Everyone is saying is great for powerstrokes right now. Blackstone tests proven too.

oil
 

I run amsoil 15-40 with a bypass filter, I change engine filter every 7k and the bypass filter every 10k and a complete oil change every 25k, I send oil samples in at 10k and 20k and they say keep running it, I change at 25k just to be safe but my buddy will run it until they suggest it being changed, usually around 35k. My 04 has 220k on it with no major problems, maybe a leaky oring but that is it. running Edge juice with att. banks intercooler, and mag. exhaust
