When I re-read the jeep forum discussion, it reminds me of how very civil people are to each other on this board for the most part. Those jeep cats are pretty abusive sometimes.

My personal experience is that it IS harmful to rubber. I was experimenting with fuel recipes in my 6.9 after reading some posts on m-100.cc about fuel additives such as toluene and acetone for knock resistance and cleaning properties and power adding. Admittedly, I did not factor in the age and condition of my fuel hoses and I ended up replacing them all, and there are a lot of them, after they turned into dust.

One guy one the jeep discussion documented his results with pictures and the evidence is there to see.

Acetone is nail polish remover among other uses.
