    So I found a gas station that has some of this plus some 110 racing octane... lol.... I am wondering if my mpg will get better in my 2014 2lt cruze.... I have run nothing but 87 octane in it since I've bought it and usually get around 30 mph average per tank... Now the big difference...

    Here is a link for a website that will find the closest 93 octane fuel near you, if you are looking for it. I found it works with the GPS on my phone and locates the nearest one just by going to the site. Just thought some might find this helpful. https://find93.com/

    I’m not super car savvy to start off with. I have a 2018 cruze hatchback lt and it’s been an amazing car for me! I was wondering if I should run premium gas in it, maybe once a month? Thoughts & suggestions? Thank you!

    I have a 2014 Chevy Cruze Eco, 1.4T engine, 6 speed manual, US spec. I've actually owned it for about a year now, and this has been a problem from the moment I got it. In hot weather, it will occasionally just stop providing boost. For a while I wasn't sure it was specifically cutting boost, but...

    I have a few stupid questions for you guys! Lurked the forum a bit, but still have some stupid questions. Bought a 2018 Cruze, and found in the manual that apparently I should only use 87 and higher, with no more than 15% ethanol. I have no idea what the dealer filled me up with, but I put in...

    It's not my intent to start a thread for or against ethanol fuels. I don't want to debate what you may have read, or the food supply, or other stories of ethanol. I want to discuss ethanol E10 and E15 in a 1.4L turbo without increased injectors and with a stock tune. Is it equal to mid grade...

    I just bought a new 2018 Cruze with 1.4L turbocharged engine, automatic. My owners manual recommends a minimum of 87 octane. I use Shell gas and I'm considering trying the middle grade or premium to see if there's any difference in performance. Also wondering if premium would be overkill for a...

    Here in my city Kwik Trip is now offering 88 octane 15% ethanol for its mid grade. If you had to choose between that and 87 octane 10% ethanol, which would you choose and why? That is today's riddle for you. Joe

    On the “High Mileage Badge Thread” CruzeTalk member “Pegasus” asked: ”What octane gas was used to earn the “mileage badge” and did you have any major engine problems?” I too am interested in the answers to that question. I’m trying to decide if I should spend a lot more $$ for premium 91/93...

    Anyone use 92 octane in their 2016+ Cruze? Do you notice much difference in a non "tuned" LE2 I thinking is the engine is tuned by GM down to advertise using 87 octane,
  11. Gen2 Powertrain
    I work as a parts guy at a Chevy dealer, and I also have a 2017 Cruze. There have been issues with detonation (pinging) damaging pistons. We just had one towed in Monday with a damaged piston. I can see Chevy eventually releasing some type of recall/service bulletin similar to what's going...

    I know 87oct - 85oct or below gives one horibble gpm. I know 91oct - 93oct gives one awesome gpm. What about 88oct-90oct (mid-grade octane) what is the gpm on that? Sent from my SAMSUNG-SM-G870A using Tapatalk
  13. Gen1 1.8L
    I was changing the cabin air filter on Penguin LS (my son's 2012 LS MT) and noticed the KRD code on the glove box label. This engine, like the 1.4 engine in the 2012 LT, ECO, and LTZ, is also coded for 91 octane. I had tested 91 octane in his car a few years back and it does indeed run...

    The "newbie" suggestions recommend using mid-grade 89 octane fuel even though 87 is normal. What do you use and why?
  15. Gen1 1.4L Turbo
    Hi everyone. Long time lurker, happy '12 Eco owner on the East Coast of Canada. :) I've read so much about octane it makes me jittery. This is not one of those "WHICH OCTANE IS THE BEST" type questions, more of a curiosity thing. I've decided with the cooler weather to drop down to 89, check...
  16. Gen2 Powertrain
    I live in Lubbock, TX where regular gas is 86 and mid is 88 and premium is like 91. I know the manual says 87 minimum but if I can save 0.20/gal at the pump I'd like to. This is my first time with a turbo car
  17. Fuel Economy
    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...

    I stumbled onto this new website today, similar to the puregas website but for those of us who like 93 octane. Not many listed so far, but thought this is something my fellow cruzetalk members could help improve. https://find93.com/
  19. Gen1 1.4L Turbo
    For the 3rd time on a 3rd different car, on a 3rd different dyno, BNR has again proven our consistent gains. On a 91 octane, mild 21psi street tune, we put down 175WHP and 242WTQ on JDP Motorsport's Dynojet. This car has intake, fully catless exhaust, intercooler, and ported intake manifold...

    So tomorrow I'm going to have to buy my first tank of gas and I would like to know which octane I should or need to use?
