This topic has been floating around for months but no one has come through with the infamous bulletin that says to change the oil level to 3.5 qts. I have concluded it is a misinterpretation of the bulletin on poor engine performance that has gotten spread around like a wild fire. In the bulletin, it says to refill with a half qt. less than specified. That is just one step away from using a half qt. less than the commonly known 4 qts that everyone uses. Walla, 3.5 qts. Things like this get started because people state things that are not fact. All the bulletin says is to prevent an overfill situation always refill with a half qt. less than specified. Nowhere in there does it say that the oil level has been reduced to 3.5 qts. People read or hear something, they process this info to what it means to them, and redistribute completely wrong information. Wrong! State the facts. Until someone can post up the bulletin that says the oil level has absolutely been reduced to 3.5 qts. the level is still 4 qts. for me.
