I recently purchased a black 2017 Chevy Impala LT with the 3.6L V6 engine with 20k miles. I love the car! That engine, when revved accelerates like a freight train (speeds in excess of triple digits are easy) and sounds like a race car! However, realizing that this is a modern engine and some of them are known to produce an over-abundance of sludge and varnish. I was wondering if anyone has any experience with that GM engine and whether it is durable or not?? Is it a sludger?? Any advice, thoughts, or good maintenance tricks would be greatly appreciated. Thanks.

I had the first gen of the direct injected version of that engine in a Buick Enclave, and I think we put 80k or so on it with no issues. It ran perfectly the whole time we had it.

My brother has it in a Chevy Traverse with well over 100k and no issues, as well. He's still got it and piling the miles on it. Great vehicle and great drivetrain.

My son has a 3.6 DI engine in a Cadillac. 190,000 miles without problems. The early one's had timing chain problems but that is a thing of the past as long as you keep up with oil changes. Dexos Gen 2 is what you want. Never heard of a sludge problem with them. The Impala is supposed to be a great car with this engine. Enjoy!

The owner of a local Chevrolet dealer, shortly after purchasing it, drove all of the Chevrolet product line and then met with his employees. He told them they've got as good a lineup of vehicles as any company on the planet. He was driving a Mercedes S class at the time, which I think was 2014 or 15, or whenever the newest Impala came out. After driving it, he gave the S-class to his wife and has been driving new black Impala LTZ's ever since. He owns a lot of dealerships, so he isn't driving it just because he's promoting it. He genuinely loves that car and raves on and on about it.

I've not driven one, but the few people with whom I've spoken that have them really love them. I really like the styling on them.

The 3.6 is known to abuse oil, at least the ones in our 2008 and 2011 Acaida did. Keep it changed at 5k and it will serve you well. I wouldn't go longer without a UOA.

Just picked ours up 2 weeks ago, so not much experience to report with, but my wife and are impressed with it so far. I did much research, these latest gen Impalas are well regarded and have earned a good reputation for reliability and build quality. Not inexpensive, but good value in the new car market place.

Maintenance tips:
-Do not be afraid to beat on it, this will help it not consume oil. Google "mototune break-in"
-Be firm with the dealership and make sure you go up the CoC upon encountering resistance. Do not let them blow you off. Keep your receipts if you get your oil changed anywhere but the dealership who will be servicing it.
-Swap the original engine oil early unless there is a reason you should not. I would do one change at 2000km and then another at 5 or 6000km and then proceed as normal.
-Drain and fill or cooler line flush the transmission fluid at 15-20k miles and add a magnefine filter at your splice if you flushed it.

EDIT: Thought it was brand new. Change all fluids.

Your "BOLD" statement concerned me as I have never read this before. Judging by the rest of the replies here, I'd say the info is false, at least with the newer models.
We purchased ours last November 17 and couldn't be happier! It has been an excellent car so far and trouble free with around 26,000 kms on it (We purchased it used with around 20k)

I have been using my favorite oil of choice in PUP 5W-30 and haven't noticed any oil consumption despite my wife only doing short city driving mainly of around 20 kms per day.

Great choice of color, by the way! Cheers2

I just finished waxing it within the last couple of weeks using Collinite 845 Insulator wax. Great wax and it sure makes it shine!

Carviewsonic, I recently asked you in the vehicle section/Impala post if you got your new Impala yet.

Glad you did and glad to read you're enjoying it.

Like I mentioned in that post, it is, by far, the nicest vehicle we have ever owned. cheers

First of call, nice car! Second, I have never heard personally of a sludge issue with these 3.6's. I have heard of timing chain issues in the early models, but I do believe that has been remedied by now with new materials and shorter OCI's. So just keep the oil changed with a quality synthetic at 5K intervals and you should be golden.
