Acura TL and Premium vs Regular Gas
However, after a little research, I've learned that this car - as well as many/most modern cars - have a knock sensor which can adjust the spark timing to prevent the knocking that result from lower octane gas.
My question probably requires an Acura engineer or very knowledgable mechanic, but here it is:
Does the TL use the knock sensor to perform at the very best it can with any given fuel, or does the TL simply revert to some super-safe-mode if it detects any knocking?
In other words, if I use regular gas, will it still perform very well (maybe just a couple HP less than documented) or will it have a significant reduction in performance/efficiency?
Thanks in advance for any comments.
