Hi, so I recently bought a Cruze, and I noticed the on the highway at least during the Fall, I was getting ~34 mpg. I read up on here about how the 1.4 L turbocharged Cruze can take advantage of higher octane fuel for better responsiveness and possibly better fuel economy, so I tried it out.
Over here we usually have "regular" = 87, "premium" = 89, and "super" = 91. Some gas stations have more options past 91 but I usually just see that.
I put premium 89 from Shell into the Cruze and my mileage apparently went from 34 mpg to 37 mpg on the highway. I filled up half the tank on Shell and later on the rest with Petro-Canada 89.
When the temp dropped to -10 C to -5C, my mileage appeared to become 32 mpg, so I filled up with regular 87 again. Mileage went down to 29 mpg. This might have something to do with ethanol blending at different stations for all I know, but basically I'm seeing a 3 mpg difference between 87 and 89 octane for me.
So for the next tank I fill up (might be a while), I was going to try super 91, possibly from Shell, and see how that goes - I'm not sure of what the impact will be during the winter but we'll see.
