seriously dude, ill give you an example, put your truck up on craigslist for sale and also put that you run tractor oil in your truck, i bet you will never sell it. or go to the ford dealer and talk to a liscenced ford mechanic, someone who works on trucks like our all the time, i bet he will fall out laughing, or just do an epic facepalm if you told him you use tractor oil its worth useing the extra money and putting good **** in your truck, they dont call it liquid engineering for nothin
