You may find you have to switch back to premium for the hottest time of the year. But until then, enjoy the savings.
I hear you and maybe but its been 90+ degrees here several times over the past few weeks, it runs great on the 89 octane.You may find you have to switch back to premium for the hottest time of the year. But until then, enjoy the savings.
I've always run 87 octane in mine, and have never had any problems with it, and I live in Alabama where is gets really hot in the summer. I have put almost 65k on the car without any issues. I know of others that do not have these issues that you guys speak of too. I guess it is just what the car gets adjusted to. Never had the stumbling or loss of power issues others complain of, my little Cruze runs good on it. Only thing I've changed is replace the iridium plugs for NGK copper plugs, and I could tell a difference in the idle and throttle response was better with the copper plugs. I get about 30-35k out of the copper plugs and regap them every 10k and seems to work great for me. For my use spending any more on 89 octane and up is just a waste of my money. Now I can tell the difference between summer and winter gas when it comes to fuel mileage. I commute about 60 miles a day to work, and on winter 87 octane I average about 33-34 mpg. On summer 87 octane my average goes up to 38-39 mpg. This is on a 13' LTZ/RS. I'm sure if I swapped to a higher octane I could probably notice a difference. If it ever starts giving me problems I will switch, but I figure if it was going to be an issue it would have shown up in 65k miles already, so I'm happy with it.
Sounds like you have a LTZ. My cousin has a 11 LTZ and he has the same luck with you and 87. it wasn't worth it to try and get him to run higher fuel as it may have been ECU recalled before he got it 2nd hand.Merc6 mine is auto. Never any problems at all. No stalling, or stumbling, no loss of power, no tune, runs as good as any vehicle I've owned. I seem to be the exception from all I've read on this forum, but there are a few of us that do not have any issues with running 87. I do understand that I am probably giving up a little power, as it is a turbo car, but I do not drive it like I stole it either. I do however pass people frequently and it has plenty of power to pass anyone I please. Never been afraid I was not going to make it around someone, as it has never given me any lag, always pulls strong. I have actually been impressed with what power it does have, and this is the first 4 banger I've ever owned. This car has 1/2 to 1/3 of the horsepower of any of my other vehicles, and to me it is a lot of fun to drive. I normally set the cruise control at around 60-65 mph, seems this is where I tend to get max fuel economy, and run the climate control in auto all year long, so compressor is engaged most of the time with the fuel economy readings I gave earlier. I will eventually give it to my daughter when she goes off to college next year, but until then I have been enjoying the fuel savings.
The 1.4 Multiair is a 91 octane engine IIRC per the Fuel Economy dot gov site.Premium here now averages 75 cents a gallon over regular so its hard to justify that much extra cost. Midgrade is typically 25 cents a gallon over regular, but a few local stations for the last 6+ years have been charging only 10 cents less than premium fuel for midgrade(about 65 cents a gallon over regular). No way I could buy midgrade for premium prices!
I have a feeling with all the turbo cars on the market today its only a matter if time before the government requires a better fuel grade for our regular, suspect most people would complain over a 10-20 cents a gallon increase in price though.
Yes, it is a 13' LTZ/RS. Never been to shop for anything yet. I received the recall for reprogramming the ECU over a year ago, just have not taken it in yet. Was waiting to see if water pump was going to go out and get them both done then. I know it is an emissions issue, but it is not affecting how well it runs, so it can wait. Bought new, and only issue so far is the broken vanity mirror cover on driver side. Was out of bumper to bumper when this happened, and not paying $60-$70 for a new cover. Very reliable and efficient car, been very happy with this car. Just change oil every 5k with synthetic, put gas in it, and change the copper plugs ever 30k as stated, is all I've done to it.Sounds like you have a LTZ.
