what grade fuel must you use in the 2005 acura 3.2 TL.

I put 2 and 2 together and got 22.

Read the Owner's Manual for your car - I bet it says Premium - 91 Octane or
better.

The TL will run on a mid-grade fuel without significant degradation in
preformance.

Everything else I've read and heard says that's not a good idea.
After paying $32 - $35K (US) for a car, why would someone cheap
out on the recommended fuel?  If that little bit of savings means
that much, perhaps a cheaper -- less demanding car -- would be
the right choice.

Lee, I completely agree with you, however the poster asked what grade fuel
MUST be used and all I did was provide a long term test report stating that
the TL can be run without on a lower grade fuel. Personally, I won't take a
chance and would use the recommended premium fuel considering the 11:1
compression ratio.

We agree. I should have answered the original poster directly.

The 04 and 05 TL should use premium gasoline  91 octanes or better.

There is a system on those cars to prevent detonation if you use lower grade
gasoline
but I tried it, and I doesn't last as long, as I need to floor the pedal
more to obtain the same thrust.
plus the carbon buildup would make it not worth it in my opinion.
if you use cheaper gas, you would need to spend more gas, and spend money on
engine clean up to get rid of the carbon sooner than otherwise.

I'm not sure I agree with this. ALL new engines have knock sensors that will
adjust a number of variables to compensate for lower octane. Run regular
unleaded, save the money, run fuel system cleaner about every 5k miles and
you will be fine. If you'll notice, higher octane's are recommended, not
required. Honda will play with the language for ex. the MDX recommends 91
yet the new Pilot (same as a previous gen MDX motor) recommends regular. Now
what does THIS tell you?

The engine in my TL has a 11:1 compression ratio.  That requires
premium.  The engine is smart enough to change it's parameters a
bit to prevent it from knocking.  However, it's definitely a
trade-off as the compression ratio is still the same.

The regular to premium difference per gallon in my area is about
$.15 - $.20 per gallon. Even at $.20 a 14 gallon fill up once a
week is $2.80 more.  After spending $32 - $35K on a new car, with
the very real reduction in performance and even the possibility
of damage to your car, why even consider such a thing for only
$2.80 a week?  If that amount means so much to anyone considering
doing such a thing, you may have purchased the wrong car.  Buy
something that doesn't require premium fuel.
