93 for my girl

I figured, but with the not-so-great MPG figures I thought maybe some people were being cheap. LOL... I get 15 out of my 2023 Ram so I am hoping to get a little better, but that seems like it may be hit or miss. And with how much fun everyone is saying these are to drive I am guessing if I get over 10mpg I am winning. HAHA....

 

[Cautionary Tale]

IS everyone running Premium octane?

Top Tier Premium 91 with boosters here. Coming up on 3k miles of city, hwy, freeway, mostly flat, always warm and some mountains, crawling, dirt n such and averaging now 11.5 MPG after thorough break-in. I have managed to get it up to 15 mpg on some stretches, but I always average out to 11.5 in the end.

I've kept my receipts, and tracked it better than I've ever done, and I have noticed some things that could trick me into thinking I had better MPG like:
-Sometimes it will click full and within 30 seconds it'll do it again but still has ~5gal left in her belly
-If I wait less than 40 seconds to top off it will generally take less than half gal more BUT if I wait over 40 seconds (40-50 seconds) then it will generally take 1-3 gallons more.
My computer mpg estimator is finally giving me accurate mpg data back but in the beginning it was waaaay off with readings of 14-16 mpg that were real-world 7-11. I now suspect I've never gotten much less than 11 but was tricked calculating 7's with early pump shut offs, but who knows.
-My truck will show or stay at full for an elongated period so it is easy to be 2-5 gal light and not know. The miles it takes to go from full to 3/4 is not near the miles it takes to get from 3/4 to 1/2, etc.

All things considered I do love the truck, minus the uconnect nonsense that needs updated or likely will be a warranty replacement here soon. I can live with 11.5 but would be far happier with 14mpg average for my adventure'n needs.

I’m looking forward to the ECU being unlocked so we can have an E85 tune (or ideally, run an analyzer for FlexFuel).

I’ve had an E85 tune on my 2018 Raptor for 30k miles and it’s been great, and saved me some fuel expense as well.

Well somehow I went from 14.5, 14.3, 14.8 to 12.6 on full tank hand calculated. Only thing changed lots of rain and wind here...

Not bad. 65mile work commute. SoCal. 91 premium, 20 mins in highway traffic, 65mph average speed I would say. Mostly highway.
