I've heard alot about the new diesel fuel not consisting of proper lubricates for items such as your VP and injectors. With the new fuel out there now, what exactly should us consumers be doing to prevent any future problems. I have read people using Powerservice Diesel Kleen, MMO, Stanadyne, and Amalgamated. Is one more of a make up for what the fuel lacks or what. I'm quite confused on this situation. I've even heard actually putting a quart of oil w30 into each fillup. Any information to shine some light on my lack of knowledge would be greatly appreciated. Thanks in advance. Having this CTD 98. 5 24 v, brother has a 2003 Duramax and a 2007 duramax with the 2006 engine, i want to make sure everything will be properly lubed. Thanks in advance.
