Hint: Use a descriptive title for your new message
If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

Here is a list of Top Tier Gasoline Stations.

87 is all you need. Telluride does not benefit from anything higher. Manual page 1-1, 1-3. If Top Tier gas is not used, it is recommended to use fuel additives every 7500 miles. Kia recommended Chevron Techron.

Using premium will not make you car faster. Just cost more money.

It make, it is very noticeable.
Refuel once and you will feel.
GDI engines run very hard. Premium even removes vibration when standing at traffic lights, for example. the engine runs much smoother. But it costs more.
Manual says 87 or higher.

What are the Different Types of Octane Gas?
There are several different grades of octane gas, ranging from 87 to 100 octane. Though some octane gas is labeled as having...

I do regular. Can get up to 35 mpg on a nice day on a flat and no traffic highway.

I use this every 10k miles or so and I love it.
Use half a bottle with high octane gas followed by another fill-up with high octane gas with the other half the bottle. So basically two full, back to back tanks of high quality detergent fuel.
Outside of that I'm using regular.
When I do the two cleansing fill-ups my vehicle feels much smoother, sportier and just...cleaner which means it's working.

Chevron w/ Techron qualifies as Top Tier.
I use 87. Y’all should see the crazy cost of gasoline in CA, especially with the gouging and the stupid gas tax that the sheeple in my state failed to repeal.

I use Top Tier from Costo and their regular only 86. That’s what I use most of the time but every now and then I fill up with their 91.

Good read on octane.
www.amsoil.com
octane has nothing to do with energy content or quality – it’s a measurement of the gasoline’s ability to resist engine knock. Higher octane denotes greater knock control.
Octane Explained: Does Premium, High-Octane Gas Boost Performance?
A recent AAA report found that American motorists wasted $2.1 billion dollars in the last year buying premium gasoline for engines designed to run on regular gas.

I read that engines designed to use 87 were low compression engines so they didn’t fully combust higher octane gas.
higher octane requires higher compression engines.
This doesn’t seem to be the case from feedback here.
whoever tried claims it actually perks up the engine ?
another documentary I watched from CBC stated that higher octane gas wasn’t any more cleaner than lower. And the names like premium or supreme were misleading?

So many myth and so much misinformation about this topic. @Senator20 was right on point with the article.
"It's not that higher-octane gas has more power; high-compression engines, designed to run on 91-93 or even 95 octane gas, will have slightly less power if you put lower octane gas 89 or less". Here is the explanation:
The octane number dictates the resistance of gas/air mixture to pre-ignite at certain pressure/temp. When the gas/air mixture enters the cylinder, the piston compresses the mixture to a point before the spark plug creates a spark that leads to a controlled explosion within the cylinder that pushes back the piston and moves the crankshaft. In high-compression engines, the gas/air mixture reaches a higher pressure/temp than in regular engines. If some of mixture ignites before the spark, it creates a situation of a multiple mini explosion before a larger explosion. This is called a "knock". As you might imagine, a "knocked" combustion cycle is not as powerful as a regular cycle without knock, therefore, the engine doesn't generate as much torque/hp.
Higher octane gas has a greater resistance to "knocking" or premature ignition, giving the power the engine was designed to provide rather than less power. It actually doesn't do anything different than lower octane gas if the engine doesn't produce high enough compression to pre-ignite the mixture.
In the end if you put 91-93 octane gas to an engine designed to run on 87 octane, you are just throwing your money out the window.
These are just facts. If you believe in the marketing gimmick of "premium" being better than regular for any car, well, that's ok. I ain't here to tell you what to do with your money.

TL;DR for everyone:
If your engine was designed for 87, adding higher-octane gas will not give you an appreciable improvement in performance, and will likely slightly decrease your fuel economy (91/93 is less power-dense because it 'splodes less easily). Putting lower octane fuel in a car designed for 91/93 is bad for the engine (Dodge SRT line, for example) - this is because the fuel tries to 'splode too quickly in the extremely high compression situation, which can lead to spark knocking. This is why cars designed for premium are "down on power" with lower octane gas - they're trying to manage running AND limit spark knocks at the same time. Stick to what your manual tells you.
