I'm a frequent poster over in the 6.0 sections but I don't know much about the 6.4s and have a question for you guys...
I saw a 6.4 pull into a parking lot today just after I parked my truck. As he drove in a trail of whitish blue smoke followed him and then he must have punched it for a second and a plume of this whitish blue smoke poured out of the exhaust.
I waited for him to get out of his truck and went up to ask him if he knew what was wrong. He told me that about a week ago the company he works for added some kind of additive to his oil which the company uses in their 6.0s to clean the injectors. They wanted to see how it would work on his 6.4 because he drives a lot. He told me the truck started smoking a few days after they added this additive. He didn't know the name of it though. His truck was all stock, stock exhaust and stock tuning.
So what do you guys think this could be? Have you heard of something like this before? What could this additive have done that would make the truck smoke like that?
I should also note that his tailpipe was completely coated in oil.
