Fuel Octane...what are you using?

I’m no expert. And i only get 87. But when my ‘17 was new, I got bad mpg’s and didn’t think I liked this new V6. I’m not sure modern engines need to break in either. But I’ve heard that the engine “learns” your habits and will improve. I was only getting 16 mpg’s until I took it on a weekend trip at about 5K miles. The road trip increased my mpg’s by a few. Now, at 30K miles, I easily get 18 i the city, 20 hwy and I feel like the shifting is better. All will the same 87 gas.

 

Ethanol is actually an octane booster. True story.

 

Wow, 16 mpgs with auto kind of sucks. Im getting 18-21 with manual and got 5k miles. So that means im gonna get 20-23 when i hit 35k?? would be awesome!

 

May have been driving with a heavy foot with the new truck too? But I love it.

 

I have yet to see where anyone has shown any, much less a significant, improvement in performance or mileage when using a higher octane in these trucks when in stock configuration. For most, I think the "improvement" in idle or performance is just in their heads as the perception that more expensive or higher octane must be better.

I try to use top tier gas in 87 octane.
