This web page has some info about how Post Injection & Bio can dilute engine oil and cause engine wear http://biodieselmagazine.com/article...;q=&page=1

 

Is there an "executive summary" somewhere? I don't understand the article.

 

I don't get it..first thing I was wondering was why they were getting fuel into the oil system. Then read post injection, to me that would be unburned fuel into the cylinder, that would do it, intentionally done to burn ash??? Is this what the newer exhaust systems are all about?? Is this maybe one of the reasons Ford was blowin fire out the exhuast> (which by the way I thought was pretty cool looking) Also they are talking about accelerated engine wear. How accelerated. Obviously I'm a little weak in chemistry and science but after all those years in the third grade I was getting a little bored with the whole thing..
