I have read many threads and articles out there and have narrowed the results down to a few contestants. I am trying to find the best all in one cleaner to throw in the gas every 10k miles or so. I have used BG44k in the past and was very happy with the results, but reading some recent articles people are saying they changed the formula and its nothing more than mineral spirits and kerosene. Is this true? I have heard good results about redline, but most people will say that amsoil PI is better, although it does cost more. For something you can pick up anywhere most people would agree that Techron is good. Anyways I would like to get your opinions on this subject. Like I said I like BG44k and I have had good results in the past, but do these people just not know what they are talking about?
