Around here
87e10 -$0.95
87e0 - $1.25
88e15- $0.92
91e10- $1.65
I don’t think the op is worried about cost,
Also the thread pointed to someone who used diesel in his gasoline truck for many years without issue besides higher fuel economy
Generally smaller amounts of modern diesel in gas will not have any detectable affect on emissions .
In the 80’s you could buy mileage master gas that had diesel mixed in right at the pump.
