What was the outcome?? Just had this message displayed on my way to work today, I'll put my scan tool on it to see the code when I get home.

30 years ago I would have been using the higher octan fuel because I was more interested in getting the most out of what I was driving. Move forward to now and I'm driving for best MPG, I stick with 87 and the money savings. No issue with Spark knock or anything close to that so I'll stay with what I have been using. If I want to race around, I'll use another vehicle that's meant for that.

2020 ST commute to work is 19 miles round trip. 3/4th of it is non highway and I average 23.5 to 24. On just highway trips I will be in the 26-29 range. Will be doing a 100 mile trip to pick up a new trailer in 3 months, so I have been looking forward to seeing how well I do down there and how it does on the way back with a 2100LBS trailer,
