Are there are knock sensors on our cars?
If so
On modern engines with knock sensors, higher octane fuel may make the engine run better if the knock sensors are retarding the ignition timing, which hinders performance??????????.....

The 2V's does not have a knock sensor, and yes, if you have an engine equipped with a knock sensor that requires 91 and you are using 87, you will have more power by switching to 91 as the knock sensor will no longer have to retard the timing.

Huh, isn't that exactly what the rest of us have been saying? All he said is that if your car requires premium and you run regular than you are gonna lose power. That is just another way of saying that do not run premium unless your car requires it, which is what we have all been saying here.

With the scenario above, you are not gaining any power, you are just getting back to what you should have had if you had used the proper fuel called for in the first place.

He by no means said that running premium will increase your power if your car does NOT require premium.

Huh......as you always seem to say before you speak.
No one could tell me if 01 mustangs had a knock sensor for sure.
I got the answer from canadastang. I guess I will just run 87-89.

Actually, search through my posts, you will likely only be able to count on one hand the number of posts I have started off that way or even used that word in. Actually, did the search for you, I don't think 3 times in 1,041 posts counts as "always".

Frankly, the way your posts were worded it was difficult to figure out what you were even asking.

Anyway, glad you found your answer.

87 here... the stock GT is tuned for 87... it dont have knock sensors so it's not liek the computer is adjusting for 87 it will run the same no matter what 87-89-93 so i run 87...

back when i had my camaro i ran 94 (sunoco) that car was stock and technicaly could run on 87 but GM did that by using knock sensors so when 87 was used it would knock then the PCM would decrease the timming too next too nothing.. it would run ok... but lost a lot of power at WOT...

same with my old turbo regal... if you read the owners manual you could use 87 if you had too... but the knock sensor will pick up the detonation and cut almost all boost out... (that car got 94 octane too)
