I bought a 2003 peterbilt 379 truck with a split tank in november 2002. Since brand new the truck never ran right, even the oil samples performed on the truck showed something was not right. I took it back many times to the dealership only to be told nothing was wrong. The dealership sent me to the caterpillar dealership because it was a cat engine, they said nothing was wrong. After spending thousands of dollars in having my truck towed from place to place and buying parts to try and find the problem myself, i found out that the diesel fuel is mixing in the hydrolic oil. The whole truck is now contaminated and is beyond repair. The truck is unsafe to drive.
