mulegolf They will run fine, but your gas mileage will not be as good. The 2007 Lexus I drive says 93 octane recommended too…I just don’t. The Durango is different… it’s the SRT and that engine needs it just to run better. Plus, we don’t use it much, wife takes it once a week to work the next town over and errands around town here and there.
We fill the tank probably every 3 weeks on that.
