What can this little engine do?

Was a beautiful day out... 63F. I was about 50 miles in to my 80 mile trip home. I drive the same way on the highway all the time. 65 mph, cruise control the whole way.. right lane. I have a 2011 Cruze, Automatic transmisison, same 1.4T as the Sonic. It's rated at 36 MPG. It took over 10,000 miles to reach 40+ MPG at this speed. When I first got it in Augist, it was a good 5 MPG lower. Break in counts for something...

Erik: When did you add the Tri-tune within the 10,000 miles? And what oil brand, type, and viscosity are you running in the engine? Any change to the stock transmission lube?

The tune helps your gas mileage a lot too. Almost all guys with the 1.4's report mileage increases with it.

That's what I've gathered from both the Sonic and Cruze boards, and I look forward to the gains if I get a tune after the 87 octane optimization is available.

I added the tune at 5,000 miles on the odo. I use factory dexos oil. No other mods. I use Sunoco 91 Octane fuel exclusively.

Thanks for the info. Steve
