How are you calculating the MPG? Are you going by the DIC, or by miles traveled divided by gallons in?
You never did mention where you happened to find no ethanol 87 octane. See one thing about filling at no name stations they buy their gas from the cheapest place they can so you will never get consistent quality. What you might be experiencing is gas from one of their crappier suppliers. At least with top tier or a name brand that should not be an issue.That was actually with a different gas station. I had to fill up before the trip.
I love this car, I do, but I am really irritated as to why the mpg dropped so far so quickly. Ugh.
I had a customer who was dealing with poor fuel economy, needed a locking gas cap. You could have the dealer check the fuel trims but really I agree the short trips are murder on MPG's, highway or not. Take it out on a long trip and see what she gets.
A tune will not improve your MPG, with your short trip with an always cold engine moving farther away from the park & ride would be the only improvement you could make.I am now waiting to see if the tune will improve that even!
I use both. My DIC is always within 1/2mpg from my actual calculations.How are you calculating the MPG? Are you going by the DIC, or by miles traveled divided by gallons in?

I would also not be using no ethanol 87 octane in anything other than a lawn mower and this is coming from a guy who runs 91 octane no ethanol 99% of the time. See once the temperature is above 85-90 I switch to 89,90 or 93 octane with 10% ethanol for the better high temp knock prevention.
What engine temps does the 1.8L run? Is it as hot as a 1.4T? Suspect that low octane with no ethanol runs like crap when its hot.
At those prices you will break even or slightly better fuel mileage to cost with 91, and I can't believe you said there is no proven facts when it's all over the site that 91+ improves throttle response rough idle and gas mileage especial in hot conditions, not to mention its just overall better for your car... I run 94 and I spend no more money weekly then I did on 83 and I don't drive like a hyper miller that's for sureI use both. My DIC is always within 1/2mpg from my actual calculations.
Sorry, never saw the question
Most of our stations down here have at least one line of pumps with no ethanol gas. I get mine at a Shell station a block from my house.
I disagree about not using 87/0% ethanol. I have always used this and never had a problem before. There has been no benefit shown with higher octane in this engine and considering the cost per gallon difference here I would have to get a significant increase in mpg to justify the higher cost per gallon. That just has not been shown to happen. Keep in mind right now my 87 is $3.14/gallon; 89 is $3.35/gallon and 91 is $3.55/gallon.
There's the problem right there. Your engine only has 3,300 miles on it. It'a not broken in yet. The rings are still seating in at this point. Most engines are not broken in (rings seated) until around 5000 miles or so.If that is really happening at 3,300 miles I am going to be ticked.
Factory ECO recommended tire pressure is 35 psi cold. I run mine at 41 psi cold.I have been running @ 32 PSI and I have barely topped 35 MPG with my Eco.
Wow my 5.7 litre GTO gets like 28.5 mpg on the highway - something is not right with your Cruze.So, I had to make a big trip this weekend. Heading out I used up the last of this tank (got 24.3mpg overall). Coming back, I filled up with 93 and drove 269 before I had to fill up. Took 12.1 gallons to refill. Average speed was 66mph - all highway driving. That is about 22mpg. This is getting worse. I'll be calling the dealership tomorrow. It seems it gets worse with each fill up.
That is not good i average about 32-43mpg depending how I drive or what traffic I get stuck in, I'm tuned with a bunch of nick nacs aNd I drive in sport mode giving her 30% of the tank, I'm a 6MT RS but you shouldn't be that far off on mpgI have had 2 cruzes automatics now and never averaged more than 25mpg with 75% city driving and air on 100% of the time.
My Subaru is AWD and Auto and it gets 18 city but it still sees 26 on the freeway and 29 on the turnpike.Wow my 5.7 litre GTO gets like 28.5 mpg on the highway - something is not right with your Cruze.
