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.

Thanks!

I have roughly 1400 miles and getting 23.1 mpg so far on 87 octane (combined street/hwy). I have not filled up with 93 octane yet due to inflated fuel prices.

Thanks kingsgambit for that information on fuel economy running 87 octane.

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.

Started a Fuel Economy thread under General Discussion.

Fuel Economy Averages

Here are my numbers on running a full tank of 91 (Top Tier) in the turbo. For reference, I live in San Diego which is very hilly driving which is not what most people think. I drove 50/50 highway/city at average highway speeds 70-75, used i-stop, and drove somewhat conservative. No heavy...

I’m in the same boat averaging 20-21mph in Illinois. But driving hgwy at max speeds so taking some responsibility. Really don’t care tho, I’m into this car!!

 

[FLCX50]

Currently on a road trip from Florida to Texas. With the turbo running 93 we are constantly getting high 29 low 30 using cruise control set to 70. About a thousand miles down so far. I briefly used 87 before the trip and my average for mixed driving was 24ish.

23.5mpg on my Turbo with 87 octane. (2000 miles)

 

[Leszekny]

Turbo premium with 1400 miles, average from mile 1 is only 19.3. 60/40 city/highway miles
Tested on regular and 93 octane gas with no visible difference.
I’m very disappointed with this performance.
Mazda is lying on theirs advertisement
Another issue that I have is jerking on slow traffic, 5mph.
I wish I could get my money back.

 

[FLCX50]

If the car is turned off and you jump to hit the gas pedal. It’ll jerk. You’d either want to give the car as quick second to turn back on or just turn off the auto stop start.

Also. I’d make sure you are using top tier gas. I’ve managed to keep my city average around 24 and I’m not a pokey driver.

 

[Leszekny]

Car isn’t turned off. I am talking about driving slow 5 mph traffic. 93 octane gas did not resolve it.

 

[FLCX50]

Mine drives smooth as silk. So I assume it’s an isolated issue then.

Mine just started this same jerking under 5mph.
