What gas should I put in my 2015 TLX V6?

In the past, before I got my TLX, I had just figured that automatics had an automatic clutch, but I was a little perplexed wondering why they didn't wear out faster - now I know it's because they have torque converters... If I had a shop with a lift, and a few spare engines and transmissions, I would try replacing the fluid in my torque converter with a higher viscosity one.
Why do you think higher viscosity will make the transmission perform better?
Do you know what fluid your car uses?
Can you name a higher viscosity transmission fluid?

The third "pedal" in a F1 car is two levers, Clutch in Clutch out separate from the up shift/downshift units. Its used to start the car from dead stop, if the car spins etc to regain control. Its not used to shift gears. Shift selection is up to the driver. Up shift right side downshift left side as there is no 'logic' to tell the car to shift or down. Under the drivers input the ECU selects the next gear. Rev matching the same function as on a normal Manual Transmission enables the shifts to be made without a clutch. Rev matching is a function of engine speed control not the transmission.

Also a lot of modern manual transmissions now run AT fluid instead of the old high viscosity gear lube. This is Tremec's recommendation for my TKO-600 5 speed rated to 600ft lbs.
"For all TKO 5-speed models, TREMEC recommends GM Synchromesh™ (GM Part # 88861800) – or equivalent, or Mobil 1 Synthetic ATF. For all other aftermarket models we recommend Dexron III ATF"
Dextron comes in two flavors III & IV. III is the most common. IV is the low viscosity version. Only other choice is FORD type F. FORD has flavors for old & new cars. The ATF's are all branded by different oil companies but the spec are what they are based on.
FWIW the trend by the manufactures is toward lighter IV style in new cars.
Follow mfg specs on this stuff & don't always think on upping them.

The drivers do not normally use the clutch manually, apart from moving off from standstill, during pit stop and in case of emergency or spin. They simply press a gear change selector lever behind the wheel to move to the next ratio. The on-board computer automatically cuts the engine, depresses the clutch and switches ratios in the blink of an eye.
That by definition is a semi-automatic transmission.

That by definition is a semi-automatic transmission.The computer does manage the engines power without the driver touching the pedal but it also matches the engines power on a Corvette MT now along with a lot of others. Is a Corvette MT a Semi-Auto?

I will leave it with this.
article 9.8.3 does say...
The minimum possible gear the driver is able to select must remain fixed whilst the car is moving. Each individual gear change must be separately initiated by the driver and, within the mechanical constraints of the gearbox; the requested gear must be engaged immediately unless over-rev protection is used to reject the gear shift requested
If the transmission can't think for itself there is nothing automatic about it. It does have electronic adds to change gears thats a given but overall its brain dead.
For fuel in the TLX use what is recommended on the filler.

In the world of the F1 semi-automatic gearbox, of course, there is no need for the driver to even think about this – everything is electronically controlled! All the driver is required to do is to pull paddle when he wants to change up or down a gear, and the electronics controlling the gearbox and clutch do the rest.

It varies by state, best advice would be for you to check your state's Lemon Laws. Often just the threat of a Lemon Law claim is enough to light a fire under a service department to fix the issue.

Start here for state info
http://www.lemonlawamerica.com
Generally these are typical conditions
""While the rules differ from state to state, as a general rule, if your vehicle continues to have a defect within the warranty period, even after it has been repaired three (3) or more times or your vehicle has been out of service for repairs thirty (30) or more days (NC has a 20 day trigger.), your vehicle may be labeled a “Lemon.” Most state laws provide that an automobile manufacturer must either refund a consumer's money and take back the defective vehicle or replace the vehicle. Keep in mind that in most states it is typically the consumer's choice to elect the relief that best suits them.""
Since you are going for #3 which will cost the company a chunk of change & may not fix the problem while triggering the 30 day part a lawyer might be able to get Acura to buy the car back without going through the lemon process.
This all ain't something you will be sucessful trying to do yourself.

If it's not an old, basic, "pre-computer"/pre fuel injection engine, I'm a noob, I wouldn't want to start trying to modify my torque converter if I couldn't replace it easily (well, I mean relatively easily - obviously it's a big job not like changing your oil :P).
Transmission fluid? I meant only the fluid specifically in the Torque Converter. Why would I need extra spare engines and transmissions? Because I'm noob and once I go mucking about trying to "improve" things, I could simply destroy it :P
I imagine if you change it you could get a different feeling from the torque converter. If I tried a "non newtonian fluid" such as a mix of corn start and water, I imagine bad things could happen...
To name a few: windshield wiper fluid, gasoline, 0W20 synthetic blend motor oil, that orange coolant stuff in the radiator, brake fluid, transmission fluid, the gas that goes in the air conditioning system is sometimes in a liquid state, and the liquid that is in the torque converter? I assume it's some special type of oil, about which I don't know much yet.
Why do you think higher viscosity will make the transmission perform better?
Can you name a higher viscosity transmission fluid?

Do you know what fluid your car uses?

The transmission & TC share the fluid. The TC's pump provides the fluid pressure to run the transmission. You need to look up the ZF9 but my mainstream ZF8 used low viscosity fluid.

OP, the moral of this thread.
The answer is to put methane into your engine. Just methane. Not propane.
For those of you keeping track at home, I'm telling OP to fart into his fuel tank.

Thought use what Acura recommends was the answer. It will cover any on the road contingency & if the exhaust valves get fried will keep you warranty intact. Think cheap insurance.

No harm continuing the thread off topic - until someone can come up with some more objective test results showing an actual benefit to using Premium gas, at least?
But,on topic, shouldn't owners of this car be legitimately pissed off, that tests conducted comparing both the MPG and performance of regular vs. premium showed no measurable difference? I mean, assume that I will continue to put Premium gas in my car, just because that's what the owner's manual "recommends" - I damn well should expect to get something more, for that extra money spend, even if it is only $400 per year?!?
Well, that totally blows away the idea of putting higher viscosity fluid in the TC - not that it would have nesc. done anything good. I suppose I'd just wish that "Sport+" mode would lock up the TX earlier to give me faster torque to the wheels on "launch"?

Just use regular gas with a drop of palmolive to keep car running clean for years, even better if using a drop of hair conditioner to keep engine conditioned

Whoever puts 87 in their cars, I hope you will disclose that fact you sell your cars. The next owners rightfully need to know.
But if you are in anyway hesitant to do that, then you are doing something wrong. Maybe?

Well, you should be pleased that you can save yourself up to a $1000 in the next 3 years, with ZERO consequence according to CR report. Aren't these forums meant to be help you with a few tricks here and there?

I'm currently driving a rental 2018 TLX 3.5L (non SH-AWD, base trim). Even though I'm mostly in eco mode the throttle response does seem a bit hesitant and seems to bit not as quick in its get up and go.
I wonder if the previous renter put in 87 and not the recommended 91. When I fill it up next time with 91 I'll see if I can tell a difference....

Nothing will make a difference. In today's world sub 5 second 0-60 is where the premium fueled performance cars have gone including KIA. Run with cheap gas unless you need to make a pass under load going up hill.
Saving a few hundred bucks a year on gas is really the thrill they are advertising till a competitive DOHC 24 valve engine comes out with the next generation TLX. Save even more with a Shell rebate card $0.10 a gallon.
