Waiting for beautiful fall colors!
When I purchased my R/T Plus, I understood that regular unleaded fuel would be acceptable to use. After reading the owner's manual, it is recommended to use 89 octane fuel. Well this is embarrassing to tell, but the small town where I purchase fuel does not have premium gas. The highest octane is 87. The super unleaded fuel is 89 octane, but I don't like to use fuel with ethanol added. What should I do? There is another small village near here (l0 miles away that I can purchase premium), but I never go that direction, so it would be an extra 20 miles every time I need fuel. Two questions: Can I use ethanol fuel with 89 octane? Is there an additive that can be used to boost the octane? Any comments or help would be very much appreciated.
