Could damage catalytic converter
i used unleaded 95 in my former 451mhd. In Denmark we have 92, 95 and 98 to choose from.
One liter 95 cost about 12 danish kroner, witch is about 8 us-dollar for a gallon :O
Today i drive a smart passion convertible cdi (turbodiesel)
95unleaded 8,69 usd pr gallon!
Diesel 7,71 usd pr. gallon!
I believe the price here for a liter is now $1.50 x 41/2 = $ 6.75 a imperial gallon.
Is ever going to end???
