Regular 87 octane here. Long commutes. If I was gonna be pulling a trailer I would maybe bump up to 89 octane, but only if it was 5,000 lbs. or higher.
Not brand loyal as I use Gas Buddy App to locate the lowest price in my area.
I usually buy brand name gasoline such as Shell, Exxon or Sunoco. ( I have those gas credit cards and get automatic savings of 5¢/gallon when I use a card )
Put over 37,000 miles in the 11 months since picking up my current Ram.

89 octane.

Impossible to tell what variables were at play(headwind, traffic flow, etc) but I've noticed it gets worse MPG on anything higher than 89.

I know it'll run fine on 87, but just put in 89 for peace of mind.

just regular for me..mid if the price is right. I try for Valero since they are a texas company but I have all the other cards. when towing it matters more to me whether the place is easy-in/easy-out like flying J or loves. BTW I saw some 1.99 here in DFW yesterday

I always get better mileage on my 200 mile to the beach than on the same roads on my return trip. I have talked with my co-workers and they have noticed the same thing. Many theories on the beach haveing cheaper gas and this or that but my theory is that even though the road appears to be flat there is still a slight drop in elavation, running down hill, when headed towards the beach, so on return trip even though it appears to be flat, I'm still slightly pulling uphill.
