Doing a 600 mile, many overnights, trip with our new (to us) 2013 Spyder ST/S the first of April. Wondering if using 87 Octane gas vs. 91 will change the performance during this trip. I think it was recommended either in owner manual or I picked up on the web to use 91. It will help on the money side a bit. Also this bike’s fuel gauge is off some. When it shows a half tank I put more than 3 gallons in to top off. Has anyone run into this with their gauge?
