Depending on how much you drive , is it worth the expense to convert?I run a 13to1,aluminum headed engine on 100 no-lead,just fine,34total lead.You do realize that it takes almost twice as much alcohol to make the same BTU as gasoline.The reason everyones mileage has gone to crap is because the additives[alcohol]have gone up replacing good old gasoline.JMO,ROY. |
