I have been attending since 1998 LOL I carry a badge and have since 2006, so Police aren't a worry. But none the less, we have a spot every year we pay for and we pretty much glamp all day and car and people watch. Will be near Mustang ally this year, will be a blast. We usually come out Friday...
Even amongst premium brands there are differences as I stated above in another post. When I had my 18GT and was tuned by Lund, they looked at my logs and capped the advance at 25*, WHILE MANY WERE SEEING 28*-30*. I was told even the top tier around my area must be so/so.
Top Tier premium is more then just an octane rating. There are detergents and additives that help with keeping the top end of your motor (valves and combustion chamber) clean. I'll pay the extra money to get the most out of my vehicles. Esp the EcoBoost vehicles.
I feel confident in saying in my household we have a lot of experience with the A10. Since 2018 we have had six vehicles with the 10R80 and 10R60.
2018 Mustang GT : zero issues and that was tuned and FBO. A lot of drag racing with 555 R2s. 12,500 miles
2019 F-150 : 2.7 EB Tuned, bolt on truck...
Just a heads up... Just tell your salesperson what you want to have your priority upgraded. I did it twice in a week. Went from 19 to 3. The sales people can put it in the system and if it green lights, you are good. May help some of those with orders not scheduled with at least the in house...
