I'm around 13.5 with my Gen 2. I drive like an ******* and it's 99% city driving with the auto start/stop disabled. Always get 92 octane. it's stock/un-tuned.... for now.

My 6.2 gen 1 I was lucky to get 10.5 out of.

About the same on my 2019. Always fill with 93; no tune; and I’ve never broken 15mpg. Even on cruise control driving from Florida to Utah twice same thing. She’s a thirsty gal what can I say

Thanks for everyone for replying to my post! This is some great info!

Just a quick update: I drove my stock Gen 1 from Atlanta to Tampa using mix of 25% 87 / 75% 93 octane blend. Ended with 13.8 mpg. I was averaging about 80-85 mph for most of the drive. The last hour of the trip I was doing about 90 mph.

I drive back to ATL today. Will fill up the tank from empty to full on 93 octane. I'm thinking I should end with around 14.5 mpg if I keep it around 80 mph. Will update...

Update: Averaged 13.8 mpg on the drive from Tampa to Atlanta. Filled tank with 93 octane and had cruise control set to 83 mph for most of the drive. I would've probably ended up with 14 mpg, but got slammed in rush hour traffic for the last couple hours of the drive.
