A question for those of you who already have their turbo CX-50’s. What is the fuel economy with regular fuel vs premium fuel. I understand that there is a drop in power and torque with regular fuel but I was wondering if there is any impact on fuel economy?

Thanks!

I’ve only filled up once with 91 octane (California max) after my dealer full tank. I’ll average the next three tanks by hand and report back. I don’t plan on putting in anything lower.

A. Depends on which gas grade you are using
B. Depends on how heavy of a left foot you are using
If you have a heavier foot, you'll never hit the MPG the vehicle is rated for. Also, harder to hit if your state allows for 70mph or higher. So far, in my non-turbo (NA) I've managed to hit MPG consistently going 70mph. Anything over that, the mpg drops into the mid to upper 20s. City has been OK. Nothing less than 22mpg. Overall, for its size and weight, this car does pretty well mpg wise and the range is acceptable (350-400miles regularly on 87 octane).

So on the highway you're able to get around that 30 mpg rating?

With the 2.5l naturally aspirated, yes. I managed to get 28 with the turbo when I did a demo. But I would disregard that test because a. It was rushed and b. I wasn't being too gentle, or too rough.
thanks for the information on fuel economy. I doubt I would pay to put premium in the turbo very often and was curious as to the Impact of 87 octane on the fuel economy for the turbo. We are currently waiting to see our local dealer’s allocation of vehicles for next month. Hopefully one of the available vehicles will have a combination of engine, option packages and color that will work for us.

If you put 87 octane in the turbo, and you drive smoothly (conservatively) you'll get 30mpg...maybe up to 32. But if your local speed limits are 70 or more, you'll get 28 or less. City is what will kill your mpg with a turbo. Honestly though, I regret not getting the turbo. But my current situation just wouldn't allow for it. If you do get the turbo, make sure you throw in 91 or 93 every once in awhile. You'll benefit from it and your engine will be happy.

My turbo is at 523 miles and averaging 18 with mixed city/highway driving on 91 in California. I’m planning to do the next few tanks on 87 octane to see if it feels any different. I haven’t redlined it or exceeded 75 mph yet.
