Premium Gas
Just joined and considering purchase of 2019 TSX. Wondering about others' experience with different grades of gas? Any input would be greatly appreciated and assist in making a decision about whether to buy or not.
thanks

There are a million different threads on this. Common theme - it is recommended by the Honda engineers, so put premium (91) in. In my case, the car is very laggy when using anything other than 91. Well worth the extra $5 for gas.

This topic has been beaten to death. Put whichever gas you like it in. I personally put premium and I'll leave it at that.

Welcome to the site.
The only thing I run regular in are my trucks. Best to put in what's on your gas cap or filler door. This topic has been beaten to death & you can do a search for the great gas octane debates.
Over all the TLX series gets pretty good gas mileage so it should not be much of an issue in a buy decision.

Obviously you mean TLX and not TSX. I've had my TLX for almost 4 years. I've tried various gasoline's and it seems to run best on 93. On 87 octane it seems to not have all the get-up-and-go it should. Often on long trips through small towns premium is not always available so I put in regular with no problem. With the knock sensors and computer control, no damage will be caused by using 87.

Welcome to the forum!
The manual "recommends" premium. But does not require it. As such you can run premium if you wish but you will do no damage to the car if you don't. The only negative consequence may be a small hit in the horsepower which, depending on how you drive, you may or may not notice.
So there you have it - don't let the gas recommendations stop you from making the purchase if that's the final hurdle IMO.
Cheers!

There are four lights!
I don’t know if Acura does anything differently, but the same engine found on the Honda models specify regular. In the end, sensors can detect fuel quality and software can adapt. Curious, if one were to use premium in the Pilot, I wonder if you get 290 hp vs the 280.

Back around 2006 in 3G days Honda listed a 10+ HP rate for premium in some tech literature that was posted to the web site . Have no idea if the current car is programed that way. Turbos are the most affected by octane because both ignition timing & boost are regulated by the octane rating.

My 2015 and 2017 2.4 TLXs run fine on regular gasoline. It's my unscientific opinion though, that mpg is better with premium. I think someone posted a mileage comparison between 87 and 91 octane fuel in their TLX.

Interesting or not. A what octane gas should I use thread has resurfaced for the 8,759,022 time.

Here is a study done by Consumer reports and one of the cars was a 2015 TLX. Interesting results I must say

Some snippets from this report

Some snippets from this report
To determine whether using regular gas in a vehicle that recommends premium gas had any effect on fuel economy or acceleration, we evaluated two models: a 2015 Acura TLX four-cylinder and a 2016 Nissan Maxima V6 (both shown below). Each recommends but does not require the use of premium gas. That guidance can be found on the inside of their fuel-filler door and is often explained in greater detail in the owner’s manual.
Both sedans achieved the same fuel economy when tested with regular fuel as they did with premium. During this testing, the cars felt and sounded the same; we did not experience any engine pinging or knocking noise in either car when using regular fuel.
The owner’s manuals indicate that drivers might notice a decrease in performance when running on regular gas, but our test results said otherwise. The 0-60 mph acceleration times were identical in the TLX and Maxima on regular and premium gas.

What’s more, in the Acura owner’s manual the automaker only recommends using “top-tier detergent gasoline”—which can be of any octane grade, regular or premium—for performance and reliability reasons. But there is nothing in the manual that equates premium gas with improved reliability.
That said, if owners make the switch and think their car is performing sluggishly, or they hear knocking or pinging, they should go back to premium fuel.
Beyond these test findings, it is key to note that our car reliability dataconsistently show that the most dependable cars tend to be those running on regular fuel.

I've always found this article interesting on the topic. They use a miata with a custom ecu to see how much power/torque can be extracted out of a variety fuels.
https://grassrootsmotorsports.com/articles/fuel-truth/
While a much simpler engine I'm sure some of it translates as they're both NA.

My experience is different on this. Finally took my car for a short road trip, ~400 miles each way. I filled up with 91 beginning of the trip, and when I got to the destination, my gas was near empty. On my way back, I had to use 89 because Shell station is out of 91, and I was too lazy to drive around looking for another one. When I got home, my car used up a little past half a tank, maybe 1/8 pass the half mark. Both trip was avg around 85-90 mph.

Don't mean to rain on your parade, but there are so many factors to gas mileage than just the type of gas that's used. Think of the elements and if your roadtrip had any elevation as well. Wind plays a huge difference in the mpg game, that's why most early hybrids look the way that they do, so they can into the air as efficiently and with less drag as possible.

That was not a professional test people. I just saying I got better mileage using 89 although I am not disagreed at all with what you all saying. Gonna try to use 89 for awhile and see the different just for the heck of it.
