Gas Problems
I have an 03 Screw 4.6 V8, 4X2, XLT, and i used to fill up using either diamond shamrock or amoco since i bought the thing in nov of 03, well i just got a shell gas card so i could establish credit, and now i use the shell but i have noticed the most horrible gas mileage now from shell, like ill fill up and it fells like a smoother drive but the mileage is like at 90 miles when the tank hits a quarter tank already burnt, is it maybe because i went from one station to another? i heard that is bad, though i let the tank basically dry before i started using shell, so the gas wouldnt mix, hmm wonder if i should go back to shamrock, anyone else have this problem?

How many miles do you have on the truck? Is the maintenance up to date (specificly the fuel filter)? I mix gas brands all the time, never had a problem. I usually use up the tank before refilling too. What was the MPG you were getting before? I get about 15 MPG with about 75% city/25% highway driving, but I have the 5.4 engine in a supercab.

I have noticed a difference while others claim there is no difference in brands
I have been running texaco 93 and been getting better milage about 18.5 mostly highway but drops to 15.5 if any city and or air on.
02 5.4 4x4 scab 3.55 265/70/17under drive pulleys k+n and Preditor
over 380 miles per tank and not at low lite. Texaco not very common station around here.

However you will get 2-5% less milage.

I track every fill up in my truck by octain and brand. Without fail, I ALWAYS get 2-3 more miles to the gallon when I use Shell. Amaco gives me the worst mileage, by a lot, and Mobil come somewhere in between.
I don't like diamond shamarock because by engine runs pretty badly with their gas for some reason.
