    Default 4.8 engine problems?

    Hello All,

    I own a 2005 Express 3500 ext. with the 4.8 engine. My truck has 143k miles on it. It runs good, but I just wanted to know if there is any problems that I should be aware of as I put more miles on it? Thanks.

    I used to drive that same van, it was a company van. I put 150k on it and never had a problem. I quit the job, so I can't say if anything ever happened with it.

    Hi Scott,

    Thanks for the response. Maybe I will give that Amsoil a try for my high mileage engine.
