Manuals Gmc 2016 Denali
GMCustomerService answered 7 years ago Hello, Page 341 of the Owners' Manual (9-63) states: R ec o m m ended F u el Use premium unleaded gasoline with a posted octane rating of 91 or higher. Y ou can also use regular unleaded gasoline rated at 87 octane or higher, but the vehicle's acceleration could be slightly reduced, and a slight audible knocking noise, commonly referred to as spark knock, might be heard.
If the octane is less than 87, you might notice a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine.
If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service. I hope this information helps! Christina GM Customer Service. Johnny answered 7 years ago I have owned three Yukon Denali's and have sold them for the last seven years.
The horsepower ratings for your vehicle (403 HP 417lb Ft of Torque) were done with regular octane gasoline. It is perfectly okay to use 87 octane. If you do so you will notice more of a 'Spark Knock'. It does not affect the reliability of the vehicle, however, does slightly affect the performance. If you can economically (I know, they cost $65,000 plus) afford premium that is what you should use. C6RAPTOR answered 5 years ago I have a 2009 Yukon Denali 6.2L. A few days ago it started to rough start in the morning when it was cold.
The engine RPM would go from 0 to 1000 RPM and skip and sputter or even stall. After it started it ran great. SIS light came on. I had GMC dealer service look at it. They got Code PIP4693D: Intermittent SES light on cold start due to DTC P1400 - Due to Low Fuel Volatility.
Was told to switch brand of fuel and switch to 87 octain. I have been using premium because I get better gas mileage with premium,especially when towing. Has anyone else had this problem? I do not like the answer. I do not want to get spark knock that 87 octain gas could give me when towing. I have had many GM cars/trucks with the GM LS engines and have always used high test gas without a proplem. What did GM do to screw up the cold start??
The GM Document that covers this problem is ID 2519009. The problem exists in 2009-2010 Yukons, Tahoes Escalades.
All of the above GM trucks have FlexFuel engines. I would guess is that the problem is in the device that GM is using to measure the% of ethanol in the gas. Nunyabusinessnate answered 5 years ago Craptor what you are experiencing is from the fuel suffering phase separation due to the high level of ethanol and moisture in the fuel. If you google 'ethanol phase seperation' you will see what I am referring too.
Remember moisture will naturally form in the fuel tank over time due to condensation. This is what causes phase seperation. If you do a search for a 'BG Products Dealer' in your area you can purchase from them a ethanol treatment kit.
This kit contains a small amount of fuel injector cleaner, and a fuel dryer. (PLEASE do not confuse this with the stuff available at your local parts stores, that stuff does virtually NOTHING. We have tested every cleaner available to us and checked the results with bore scopes (basically a small camera on a stick) and none of the cleaners proved effective.) you can purchase this product and use it once a year. If your remove the ethanol pool at the bottom of your fuel tank you should find that this rectifies your problem.
On a side note your dealer is incorrect, and misunderstood the information gained from your cars computer. Fuel volatility is related to octane rating (the fuels ability to resist destination while under pressure.) and the presence of water in the fuel will play a huge rule in this matter. If the fuel lid states premium fuel, that is what you should use period, end of sentence! I would change fueling stations ( GM and many other manufactures recommend the usage of 'Top Tier Fuels ONLY' in their vehicles searchable as well under the title 'Top Tier Fuels' these are the stations whom sell this specific blend of fuel.

The previous poster stated that it was not harmfull to the vehicles engine if engine knock is present. This is 100% incorrect. Engine knock is the MOST damaging event to take place inside and engine because the fuel is igniting (detonating) before the piston has reached the top of its compression stroke, this is VERY bad.
Hope this helps. I am by the way an ASE certified Master Technician. AutoCentric answered 2 years ago A HUGE marketing research study, Optimized chemical mechanism for combustion, the MIT researchers deemed AKI — and more specifically, MON — to be an outdated measure of engine performance, originally designed to apply to older, carbureted engines rather than modern, fuel-injected engines. To bring the octane rating system up to date, the team considered doing away with MON, and basing engine performance solely on RON. ' Virtually nothing is gained by filling up with a premium or more expensive grade of fuel than the vehicle manufacturer has recommended, the experts say. And many of the same experts explain that drivers may not lose much performance from their cars by using a lower grade of fuel than recommended by the car manufacturer. There is little difference in energy content of regular versus premium gasoline.
They both contain about 111,400 British Thermal Units of energy per gallon. The price difference, however, between the fuel grades is anywhere from 20 cents to 40 cents, depending on where you live in the United States. The experts' consensus goes against the long-held belief by thousand of drivers who fill up with premium only, or on every third or fourth trip to the pump.
The idea is to fill up with premium every so often to clean out the engines or rev up the performance of older engines. But according to the experts, this practice is like tossing quarters in a wishing well, since most engines are designed to operate on relatively low-octane regular unleaded gasoline.'

Digital Owner Manuals now contain full content and are searchable in the app (2008 or newer vehicles). Locate Vehicle feature now available in both the Navigation and Parked Location cards (available to eligible US OnStar subscribers). Forgot username/password process improved. General bug fixes and performance improvements. 3.4.0 Jan 10, 2017. Tark Jones Overall it's a solid app. It does the basic stuff well.
I primarily use it for remote start which is great since its essentially unlimited range. I've also been able to unlock my wife's truck for her when she accidentally locked her keys in it. It works well the majority of the time, but can sometimes have an issue with a signal getting through if you're in a parking garage - which I assume is a function of the service provider not the app itself. Overall its a very convenient tool to have. One thing to watch for - if you have two GMC vehicles on the app, double check to make sure you have the correct vehicle selected. I have started our other vehicle by mistake when it's sitting in the garage. To the developer: it would be nice if the banner image reflected the vehicle currently selected, instead of a generic GMC line up.
That would provide an easy identifier for those of us with multiple GMC vehicles to quickly confirm which vehicle is selected. Even allowing the user to upload an image would be a useful option.

Gfyogamom.UPDATED (see my original review below).
After my original review, several emails, etc., the app finally began working correctly. No official determination on the actual problem, but I’m happy that it actually works. It IS a GREAT app and I’m happy to be able to leave a positive review. Both OnStar and GMC are awesome companies that have excellent customer service.ORIGINAL REVIEW. I LOVED this app, until it updated and took away all the features I use. Those features may still be there, BUT since the app refuses to identify my OnStar account (which I have confirmed is current with OnStar), I can no longer use them. So, I cannot remote lock/unlock or start my car, check diagnostics, send addresses to my navigation, etc.
All these functions are the purpose of this app for me, personally. I am very disappointed.UPDATED (see my original review below).

Winter Soldier 71 So after two years of having a General Motors vehicle, a GMC Yukon Denali and having basic OnStar which I feel should have basic features I have had my send to navigation option taken away from the app after two years with no notice and no consideration for the fact that we own multiple General Motors vehicles.
You took away navigation from the consumer in order to force a sale of higher priced OnStar services which I feel only makes your product now look less desirable and I hope that everyone reading this will consider not purchasing a General Motors vehicle based on the heavy-handed approach that you have taken and taking away the liberties of a simple send to navigation. I noticed that as developer you were leaving remarks back to bad reviews please don't bother leaving a standard copy and paste remark telling us about how awesome General Motors is when all you do is take away features and force people to pay for things they didn't have to pay for before. I moved from Jaguar and Land Rover to GMC and Cadillac, I have owned BMW and Mercedes very happily. As quickly as I divorced them I will divorce you General Motors and I will go back to your German adversaries. This is an absolute shame in business ethics that you would resort to nickel and diming a simple navigation feature to try and push your ill prepared and very non-feature-rich OnStar services.
