unleaded gas

[mgbgtn]

Because Fiat dual cam heads are made of aluminium they already have harden valve seats installed and can use unleaded no mater what year they are. It is only older cast iron heads that require harden seats to prevent the valves from hammering themselves into the head because the cast iron is soft and the lead used to cushion the valves to prevent this.

I wouldn't worry about using unleaded fuel in our cars. E10 and the soon to be E15 however.....don't get me started
Corn is meant to be eaten not burnt! Too much cash changing hands to do much about it though.
23 billion US dollars spent on ethanol subsidies since 2005 (source: Congressional Budget Office), and it will cost an estimated 2 billion dollars to install separate E15 blender pumps at gas stations to avoid mis-fueling.
