I fill my 2021 1500 Limited up with the non-Ethanol 90 octane grade from a station that sells "Top Tier Gasoline" (whatever that really means). Because we are working from home, there's weeks where I may not drive more than 30 miles, and I don't want the ethanol sitting in the truck for long periods of time.
Have the auto manufacturers adapted engine designs so that ethanol no longer causes problems if it sits in engines for long periods of times?

Top Tier contains extra detergent to maintain cleanliness longer. Injector nozzles only for GDI engines, nozzles and intake valves for SMPFI engines, like our Hemi's.
