I'm not remotely a gas expert, but is there a seasonal blend that's now being delivered? Same gas stations?
The thing that really bothers me is the sticker, which said 17 city, 22 highway. Not only can I not average 22 on the highway, I can't even get close to 17 on the highway. If I can get the truck into eco mode on a flat straight stretch, maybe it'll hold at 18-21, but it's temporary. And that's *indicated*! I've found by tank calculation that it's about 10% optimistic.
Ram's EPA numbers are egregiously erroneous. You'd think after 20 years of engine technology evolution that I'd be able to do better than my 2001 4.7L Dodge Dakota. Sure, the Ram's is a bigger engine and a heavier car, but it's still supposed to be wildly improved after all this time.
