I will note that I do burn 89 in my V6 most of the times and will throw in 91 when going on long trips with a full load. A full load for me is 4 people, luggage stacked in the back, and a hitch mounted rack full of storage containers for supplies and overflow. I might notice a little better performance than 87, but the big thing I notice is the black soot at the twin chrome tailpipes. The higher the octane, the less soot I notice between wipe downs. The majority of my gas is BP so it is a Top Tier rated fuel. Just an observation as I figure if the tail pipe has less soot, there should be less build up inside the combustion chamber, past the exhaust valves, and through the exhaust system.

What is important?

87= soot in my 2.0 t also check engine light twice and a problem with the ecm throwing codes. Stupid me for taking for granted GM would not be so @#$##@# for designing a motor that must burn 93 most of the time. After now reading the manual, I understand its not my choice; if I don't want to tear up the car (evidently). I noticed soot on the chrome tail pipes with only 2000 miles from I think was using 89. I'll report back after a few tanks of 93, if I can scrape together a few extra dollars that I could have spent at the walmart grocery store.
I was hoping to read the forum and learn fact but instead not sure what it was?
I know one thing the V6 in the arcadia I rented while my nox was hopelessly being examined at the dealership (to no avail), had plenty of power and was great on gas. I think the bottom line is it takes less to build a small 4 even w/a turbo than than it must to construct a v6 that runs sometimes just on 4 to conserve. In other words. I feel the 2.0 T of mine is cheaper and will not last or endure as much over the years. It fly's when the turbo powers up... but the Bang for your buck is missing. That V6 was nice. I will not make this mistake again I promise!

I have two Equinoxes, one with a 2.0, the other a 3.6.

Both are direct injected which will leave soot in the exhaust tips.

It is true that the 2.0 is best fueled with 93 octane to get the best performance, economy and engine protection from potential LSPI damage.

It is true that the 3.6 is probably more expensive to produce, weighs more and gets worse fuel economy.

It is also true that the 3.6 is also less complex, uses regular grade fuel, and will potentially have a longer service life with fewer problems along the way.

My 2019, 2.0 is my daily driver; it gets good fuel economy and is very powerful and fun to drive.

My 2016, 3.6 I only use for trips and is overall a better, more solid, substantially constructed vehicle that I expect will provide years of trouble free service.

Unfortunately there isn't a V6 option in the Equinox anymore; but there is the new Blazer ---

There also is the GMC Acadia, which is essentially like the Blazer but also has the 3rd row seat option which, if not used, increases cargo space dramatically.
I had over looked the Acadia until I found pricing that was at or close to $10K off MSRP. That meant we could get into a 2019 Acadia SLT-1, with a V6 at just under $31K with an added 2% for GM Loyalty incentive.
I was considering the Blazer in maybe a year or two, but when the Acadia deal came along. . . too good to pass up.

We got the new Acadia for less than it cost for our 2015 Equinox LTZ.
In my opinion .. .. anyone who might be interested in having an Equinox very close to the size of the 2nd Gen ought to monitor deals on the GMC Acadia. Built in Springhill, TN. . . along with the Cadillac XT5. We are impressed with the quality, fit, finish and initial MPG we are getting that is even somewhat better than our 2015 Equinox V6.

Iím surprised that GM hasnít promoted the Acadia more. I see a lot of Blazer, XT5, XT4 commercials but very few for the Acadia. There was tons of negative comments on the Acadia forum about the new size when it was first introduced. As JayTee has found out for those that donít like the new size or the Turbo., or Start/Stop in the new Equinox/Terrain the Acadia is a viable option.

Yes, forgot to add that the Blazer's origin is Mexico. Both of my Equinoxs' are Canadian.

The Acadia is a wonderful choice right now; made in USA, incentives, a V6, no stop/start, naturally aspirated, 87 octane fuel, etc.etc.

Thanks for the info. Right now my stresses are about having my first car that I always thought i might avoid and realizing how most gas stations attract customers with low regular and slap premium users in the face. I think I just need to resolve some issues because my millage was substandard, the problems will reveal itself then I am sure I'll enjoy it more.

And that is a consideration that many have no realization of. Low Speed Pre-Ignition is a very real problem with direct injection gasoline engines. Proper oil is a component of preventing it as is the right octane fuel. LSPI has the potential to do a lot of damage internally.

This is why I often wonder why the newer turbo gas engines are generally not flex fuel capable. E85 has an octane rating of around 100.

Freedom is not the ability to do what you want, but the ability to do what you ought.

While I respect the opinions and the points of view. I too have over the last 30 years of driving, had a Chrysler Laser 2.2 Turbo, Cadillac STS, Cadillac Deville, both with NorthStar engines, Pontiac Grandprix with 3.8SC, Two Chevy Trax, 13,15 and now the Terrain 2.0. Not one issue with using 87 octane with only the Grandprix really needing 91 for it to produce a little more power. Granted there are vehicles that must have high octane, any Cadillac 4.9 engine, and the 4.5 as they do not have the knock sensors to retard when required.

It also looks like GMC is bringing back the 'Jimmy' for the 2021/2022 MY. It appears that it will be based on the Traverse and Enclave bodies which would make sense as GMC does not have a vehicle in that size anymore, notwithstanding the downsized Acadia. Google it and see.
