Yea, thats kinda what I was trying to get it.
My SHO said "Recommended" and it really meant that it was JUST recommended, not required. It ran fine on Regular, but didn't have as much power (as to where you did notice it), and usually got about the same MPG
but I can't imagine feeding something like a Terminator 87 Oct...
Realistically, if you are buying a car made in the past 2 decades that requires premium, you can probably afford premium gas, or you'd be smart enough to not buy that car...
with gas being as expensive as it is, Its 100% irrelevant.
back when it was like $2, maybe even $3, it could have been a point, but now, % wise, Its nearly nothing.
It cost $50 to fill the tank in my focus @ 3.83 a gallon ( 13.05 gallons of a 15 gallon tank)
So it'd cost $2.60 more if it was premium, or about 5% more...
Back when gas was 2.49 a gallon 13 gallons would have been $33.80, and it'd still cost 2.60 more if it was premium, so it'd be 7.6%, etc, etc.
I like this part::
“There generally isn’t any harm done to the engine by using lower-octane fuel,” said a BMW spokesman, Thomas Plucinsky. “Because our engines do have very good forms of knock sensing and are able to deal with lower-octane fuels, you will not have any drivability issues. You will, however, lose some of the performance.”
"Generally" and "Able to deal with" aren't exactly BMW saying "Yea, go ahead, Throw Regular in the car, its fine!"

Cars get their best MPG running just enough octane that it needs. My old GT ran KR free with 89, however, everyone said 93 was the best since it had a reprogrammed PCM. I ran 89. Saw better times and more MPG. 87 my MPG got worse and the car started to knock.
I didnt even see this comment, but I will X2 it. I upped the idle and cruise timing in my car to the point just before it knocks and saw a decent little jump in MPG.
I also finally decided to read the article. Yes, knock sensors can help your car fight knock. However, IMO, you dont want to rely on them to drive day to day just because you are a broke ass chump.
eh....much better filters out there than K&N. if you truly care for your car you'll use something like an aem dryflow or amsoil dryflow. hell paper is better.
I wouldnt say paper is better then K&N, but Id agree that a dryflow is better. I have a cheep Spectre filter from autozone just for the simple fact that it was the only one I could find on such a short notice that would fit my intake.
