When it comes to fueling your Palisade, which fuel grade do you prefer? Does everyone stick with regular 87 octane gas, or do your prefer premium?

From my understanding there isn't a big difference in performance or fuel economy between regular/premium gas, but I'm curious to see if anyone has noticed anything with their Palisade?

87 octane. I do however, select a gas station that advertises top Tier gasoline.

Look up top tier gas companies on google and go to one of those and just use 87 regular. If the engine is not designed to make use of the higher octane gas such as 89 or 93 etc, there is absolutely no benefit. The top tier gases have more detergents in them than other gas stations and that over time will make a difference in keeping your engine running stronger, cleaner and efficient.

Somewhere in the front of the palisade manual in mentions using top tier gasoline and advises to use an approved fuel system cleaner i beleive every 3,000 miles if you do not consistently use top tier gasoline

That's very true a lot has to do with which company you fill up with. Is there a particular gas company that you like to use? I usually go to Shell for my gas.

I use shell most often since it is close to me. I also use BP and surprisingly I get Costco gas whenever I go there. Not sure if you have a Costco near you or belong to one, but they are actually known for having very high quality top tier gas. Quite honestly, as long as the fuel station is rated as "top tier" I would not worry at all.

There is a Costco near me but to be honest I've never used it for filling up with gas. I had no idea they had good quality gas.

Car engines are designed to run on a specific octane rating. As an example I have a 2015 Toyota Tundra with the V8 engine and it requires only 87 octane. I have a 2006 Lexus LS430 V8 that requires 92 octane or better. Both cars run excellently with their specified octane. The Palisade requires 87 octane and is tuned and programmed to run optimally at the octane rating. I use Sam's Club fuel for all by vehicles.

I use cost co gas its top tier gas plus its the most newest gas you can get think about this how often at costco do you see tankers filling up the costco tanks almost every other hour that means it does not sit in a holding tank very long. i fill up my 03 range rover and07 jeep Cherokee 2020 palisade there best bang for buck an good quality

That's very true, I never considered that either with Costco.

Sams and BJs both sell very high quality fuel. I know as I am the owner of 2018 GM 8-cylinder engines, these GM engines are not just picky they are fussy, especially recent ones. They would rough idle on anything but best fuel. I was told Exxon/Mobil is good fuel, maybe for some but not for GM. Valero is the best branded fuel I found, as for non-branded it is BJs and Sams. ... Costco... not so much for GM engines, but was perfect for Toyota. Palisade and Yukon both use GDI engines and in fact if not mistaken Palisade is even higher compression at 13:1, thus GDI will be sensitive to fuel down he road, use TopTier gas. No need for Premium though. Once every 10,000 miles use Liqui Moly or Kano Labs fuel cleaner and it should be fine.

And their gas prices are consistently low. They consider it a customer satisfier and won’t jack the prices up if they don’t have to. It is something they will take a loss on to promote customer satisfaction

Costco locations where I live only carry 85 or 91 octane. No 87 midgrade. I've used 85 so far with no issues, but I'm wondering if I need to spend more $$ to go to a gas station that offers 87 octane.

The manual says the minimum is 87.
87 is actually usually the lowest. I buy Gas mostly at Costo too and its 87 or 91 by me. You do not need to use anything higher but using anything lower is a knocking risk and degrades performance at best.

FUEL REQUIREMENTS
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL, as well as mini- mize exhaust emissions and spark plug fouling. Your new vehicle is designed to use only unleaded fuel having an octane number ((R+M)/2) of 87.

I googled a little and apparently in some high altitude area there was the thought no longer true that older cars could operate as well on 85 as 87 in high altitude places and minimums are stuck at 85 and you have to overpay to get 87 etc.

Are you driving the vehicle at higher elevations, this might explain the lack of 87 octane and the availability of only 85?

This link might aid in your understanding of Octane vs Elevation:

I am not an engineer. I good at googling to supplement my ignorance.
