I was just wondering while fikkling up my L300 this morning, is the ECOTEC engine in the SKY set up to perform at regular unleaded, or will the use of premium unleaded be required, is there going to be noticeable difference in performance between the two. I realize that most all engines today are set up on the lower octane gas to perform at their maximum, but want to if any advantage gain by use of higher octane. It isn't a problem for me to use the [premium unleaded, but won't if there isn't a significant change in performance.
