Unleaded fuel

[stemar]

Hello,<br />My country soon (by 2004) will be full member of the European community. The regular fuel(98-octane) will no longer permitted for use because of the European law. We will only be able to use unleaded (95 or 98-octane). So far I was using for my 1989 90HP Mariner outboard regular(98-octane) fuel. Can I use unleaded fuel for my engine or is there anything else I should do to solve this problem?<br />Thanks

Hi, Stemar.<br /><br />It depends on your engine, and the manufacturer's recommendation.<br /><br />Most modern engines do well on unleaded regular, but some automotive conversions for inboard or I/O may require lead or a lead substitute.<br /><br />What engine do you have?

stemar,<br /><br />Your outboard doesn't need or care about lead or lead additritves. <br /><br />The octane is the important factor. Just use the new fuel that has as close to the same octane rating as the old.

We had this problem in England 2 years ago. I was told then that all mariner engines built since 1966 could stand the lower rated unleaded fuel.
