2019 Gen 2 owner here. Wondering if anyone else had any noticeable differences running premium in their engine. I’m not sure if it’s just my brain tricking me but I put premium in the car for the first time sense I bought it and my car seems to be running a lot smoother (other than chevy’s...

Having used regular unleaded for the entire time I've owned the car, I recently tried premium gas for about 4 straight tank fills. I noticed an improvement in performance, but it seemed like the entire time it had premium, the engine light was on. When I switched back, it went off. Maybe I...

Hello, I've got the 2013 RS 2LT, and the one thing it did not come with that I'd really like to add is the factory premium sound system. I know that system has a built in amplifier, but I'm wondering how much modding it will take to add the factory wiring harness for that amp? Has anyone done...

I am trying to figure out why the sound is sometimes distorted and the bass comes and goes in my install. There is also a thump a couple of seconds after opening the door with car off. I also noticed that turn signals and some chimes come through the speakers. What I have done: I tapped into...

Hi guys.. dumb question.. I need to replace the speaker of the right door, and I found that there's two options. speaker w/ premium audio or w/o premium audio.. Which one? I have a 2012 LT it have a center speaker in top panel, one on each door, and two rear. Any help? Also, if you...

An interesting article. It's from 2007 though. https://www.scientificamerican.com/article/fact-or-fiction-premium-g/

So my lease on the 2014 is running out and went into discuss what happens in April and walked out with a new lease on a 2018. I really liked the 2014. My questions to the group ... will the rubber floor mats from the 2014 fit the 2018? Anything I will notice which is very different?

Breaking startling news from the AAA today. This is a 180 degree reversal from what they have been claiming over the years! _____________________________________________________________________________ Drivers are wasting their money if they use more expensive premium gasoline in vehicles that...

This is getting very confusing. After reading this article https://www.digitaltrends.com/cars/why-new-cars-recommend-premium-fuel/ Yeah, G.M. say 87 octane is fine but I heard here and a few other places that 91 is better. Is this just placebo like this article says or is there TRUE and PROVEN...

So I was thinking, Premium fuel is pretty high in price. I usually fuel regular. And as some have noticed, the Cruze doesn't do well with regular when the temps exceed 100F. I was thinking in my 13Gal fuel tank, to add 2 gallon of E85 fuel for every 11 gal of Regular fuel. It should be exactly...

How much extra do you pay for premium? I can remember for the longest time Regular would be a certain price, mid-grade was 10 cents more than reg, and premium was 20 cents more than reg. I yern for those days. Now that both of my cars run 93 octane and I frequently pay 50 cents per gallon more...

I purchased in September 12 a new 2016 Chevy Cruze LT I love my car alot, but I just noticed a tear on the passenger seat on the side where the console is. My question is will this be covered by warranty this is weird previously I had a 2012 Chevy Cruze LS for 4 years and the seats were in...

I've been a diesel head for a number of years, although always trucks. I noticed up here in Wisconsin that the Kwik Trip stations carry something called "Premium Diesel" with a four cent premium price. I filled up and on the same fifty mile stretch of road at the same time I broke the record...

I only bring this up because it was mentioned on the "consumer reporting" portion of our local news. Honestly I don't think the guy that started this complaint to our consumer reporter:1)Buys much gas or 2)really pays attention then all of a sudden he looked at his gas receipt and had a...

I ordered the GM OEM splash guards / mud flaps for my 2016 Cruze Premium RS and there seems to be a problem with installing the front splash guards. (They just do not fit) When I ordered the splash guards I provided my VIN to verify fit. I have done some Google searches and from what I have...

My cruze was running like garbage so I tried some fuel cleaner like you guys suggested on here and it worked good until it ran out and then went back to ruNing like garbage after I put more regular gasoline in. A week later I tried premium gasoline and it went back to running flawlessly. What...

I'm up here in Canada and became aware that certain Shell stations in Canada sell premium diesel fuel. Its called V-Power. I decided to give it a try (8 cents a liter more). I'm just a few km's into the tank so I will post at a later date with my impressions.However I did notice something...

I wanna hear what you all think of this

Has anyone bothered to play with the premium sound system at all and found any mods that are really worth the money?
