The Acura magazine distributed by Acura a bit over a month ago mentioned
that the use of regular gas in the Acura TL, instead of premium gas, would
result in only an undetectable loss of power (and could save quite a bit of
money). Has anyone any experience with effects of using regular gas in the
TL. I have a 99 TL and would appreciate any info.
Thanks.

One should really have hard data on THEIR car before deciding on gas
I've come to decide. While taking a stats class I began recording info
on all my gas purchases and putting it in a spreadsheet. What I've
discovered is that I get best mileage and performance out of 87 grade
(5000+ feet) Conoco or Shell. I can base this decision on about 1.5
years of data now.

For the record in the summer I can get 29mpg with a std. dev. of about
1.8mpg, with heavy a/c use (black car), manual tranny, and proper
driving technique. That is to say I drive like a bat out of hell most
the time but also employ proper coasting, approach intersection slowly...

Data analysis is the way!

Now, to answer your question. The car's engine has a knock sensor so
that if you use gas that might otherwise cause a problem (low octane,
pre-iginition) the computer can compensate for it.

We use Plain-Jane regular in our '98 TL. It runs fine. In fact , it runs
extremely well. Once, I put super-duper in it, just to see if I could
notice any difference. I couldn't, and the MPG was the same.

The quality of our fuel today is crappy, at best, regardless of grade. My
69 MG manual says to use a premium grade fuel, but in any case, not to use a
fuel with an octane rating of less than 98...... har har. I suppose you
could get something like that at the airport. Fortunately, today's cars are
made to run on this low quality junk they sell as fuel.
