This is interesting. Is this another acetone rabbit trail or real? Anyone do ABA testing?

Since diesel has a slightly higher btu content, is this the reason for the power and economy gains you all are seeing?

For those that are adding diesel to gasoline:
1) What are the mix ratios you are using?
2) What are the gains in measured mpg you are seeing with those ratios?



For me, I add about 1oz/gallon or about 1:132 of filtered (<1 micron) used engine oil to my fuel. Have been for over 6 years now. It doesn't cost $4/gallon, it's free.

Effects: No measurable effect on MPG but it uses most of my drain oil up between changes. My truck is really sensitive and wants mid-grade most of the time anyway so the increased suseptibility to knock is not tolerable. The Kawasaki tolerates it even with a 4* ignition advance, has very slight ash deposits on the plug. The Odyssey doesn't bat an eye. The 2011 Dodge Caravan for my vanpool doesn't care.
