well I did get better gas mileage from going to the ethanol free, currently it's about 8% more than 87 but I got about 16% better economy, probably not much of a power gain but economic gain is great...

I ran 93 (my "premium" around here... 87, 91, 93) in my truck for a while and didn't really find any performance gains in my 5.4 after about two months. MPG seemed to increase but very minimally, so much so that it was counterproductive to even bother with the extra $. I changed stations from my former place of employment (Wawa, if you're from my area) to Shell and noticed an MPG and overall driveability improvement. Perhaps from whatever Shell puts in their gas. It's a few cents more expensive, but nothing like the premium I was putting in, and it seems to be worth the money.
As for brake standing... I can do that on any octane. One wheel squeals, baby. But I don't do it often as my tires are pretty much brand new as well.

Nugget, do you have a limited-slip rear end? I have a 2000 4.6L with 3.55 gears and a limited-slip rear end. I can't get my tires to spin unless they're on gravel or if it's raining. However, if I really hit the gas on dry pavement I can feel one wheel slip and the other wheel catching and stopping a burnout.
As for octane making a difference. Im not even going go there. Too many wars on that already lol.
All-in-all I think your trucks fine. As for gas milage, I get around 15.6 mpg highway and 11-12 city.

I have no idea if my 5.4 can burn rubber, so you may not be alone.
Why you ask?
1. I just bought new tires and have good brakes
2. I don't run 104 octane race gas...only because I'm 'too cheap' says Jr a few posts up (softcorefx4)
3. It puts strain on a lot of components that i don't want to shorten their life
4. I'm not a 16 year old
5. My truck does everything I need it to power wise
Have you tried putting it in neutral, revving to 4-5k then dropping into drive quickly? You might get a chirp out of that. You will feel tha powa then!!

My 5.4 will smoke them. And my 97 4.6 will squeal them pretty good. Try running 91 octane. And don't listen to other members when they say its the same. Because its not. They are just to cheap to pay for good gas. Try a few tank fulls and I bet you it would light them up better than ever. When I got my 03 5.4 supercrew. it wouldn't even squeal them the guy before me ran 87 I put 91 in it since I've owned it.
