I'm new to the board as a lot of Spark owners may be. I live on Lake Livingston in Texas. Thanks for having me aboard. I have been using Royal Purple "High Performance" for many years in my other engines. This oil is a full synthetic 5W-40 with an API "SN" and ISLAC "GF 5" designations. Our summer temps are typically in the upper 90's and would not be running the skis in the winter temps. Any ideas on the suitability of this oil?
