Truth in Ruin I've only ever put 91,93,95,100 octane in it for over a year. So the 87 was very noticeable.

"Cutting out" = boggy dog shit... Does that work?

Rath Rides it shouldn't be "cutting out".....

This is no joke. Those that say they can tell a difference aren't lying; it's not a "placebo."
Pretty sure it would learn that 87 was thrown in there and reprogram itself to compensate after some driving.

It's not THAT huge of a difference but I can see if the car was used to premium then suddenly got a dose of the cheap stuff, it would still be using premium tuning parameters.

you're not wrong. The non-turbo foci have 12:1 compression. and higher octane fuel will run better. That's not to say lower octane fuel will run bad, though, because of the knock sensors. If ford says the engine will run fine on regular, then it will. However higher octane fuel WILL resist detonation far better in high compression engines.

The old 2.0 zetecs have a compression ratio of 9.6:1
So, running higher octane fuel in a zetec will be more "silly" than it is to run higher octane fuel in the new foci, with a 12:1 compression. yes, the knock sensors come into play, and will do so more in the higher compression engines.

My '97 Escort doesn't have a knock sensor but the 98+ do.

So yeah for the most part everything modern from Ford has a knock sensor AFAIK.

you have to remember also that our cars are high compression which runs better on higher octane gas. the only reason our cars can run regular gas is because Ford put knock sensors in the engine to prevent knock from using regular gas. our engines do run better on premium. the 2012 models actually stated it in the owner manual. it said for better performance use premium.

sorry if I'm a little off in my description there, I'm no expert. just info I've gotten from this forum.

same. up here in Washington it ranges from 20-30 cents difference which is not a big deal to me. My car is tuned for it and I don't mind paying the extra couple bucks a tank to fill up. I see premium gas the same way I look at synthetic oil. it's not required but if you can afford to use it then why wouldn't you? it's definitely not going to hurt anything and most people who use it say it makes the car better.
