Not to offend. . . . but every automotive forum, reviews and articles I've read on buying vehicles has conditioned me to avoid anything with a turbo engine. No matter how advanced, how high end, they always require more care, monitoring and maintenance, second only to owning a diesel.
And the regular/premium fuel question is just another aspect.

At this point, when I need to purchase my next passenger vehicle, I think I would even prefer a hybrid over something with a turbo.

The types of problems I always seem to read about are waste gate problems, air intake or vacuum leaks, oil contamination of the turbo due to PCV issues, and more.

I hope and wish the best for anyone with a new Equinox/Terrain turbo, but I am pretty much holding my breath to see how things pan out.

This is exactly why I leased mine, easy to walk away from when the time is up.


My dad has had a couple issues with his 12 turbo cruz and he is looking to get rid of it now. His solstice is a turbo too but I think that little car has less than 5,000KM on it after 10 years lol

When I replaced the turbo on my Cummins it was about $1,200 plus labor, out of warranty of course.

I want to say "Ouch!" but also that seems decent to include the new turbo.

The sticking point with Octane is that most people think it makes more power. In truth, the only thing octane does for you is allow more compression. So we see a 600 HP street can and see that it needs 100 octane and make the link that octane=horse power. No, if you run fine on 87 octane gas, 93 won't change anything. If you bump up your boost with a larger turbo, or advance timeing, then you probably would do well with higher octane gas. Until then, save your money.

My 3.6L Camaro has 11.3:1 compression ratio and is rated at 323 hp on 87 octane; able to do so because of the Direct Injection--no pre-ignition because the fuel isn't there until just before the plug fires. Computer controls make some things so much easier with engines.

My 2014 LTZ 2.0 Turbo had over 50,000 miles with nary a problem. Granted, I don't know what it would have been at 100K or 150K, but it's been years since I drove one to that distance.
