Try filling up twice a week with 93 octane.

I feel your pain but only worse....

Ok, I finished the tank of premium. My result was the same as regular gas, about 18 in all city driving. Although I did notice it didn't have the knock when not giving enough gas in 1st when letting out the clutch.

uhh 4 bucks a gallon? ive been complaining bout the 3.45 around here. Oh and filling on premium cost an extra 4 dollars per tank roughly, twice a week, times 52 weeks...is roughly 410 bucks a year, so I wouldnt rag on people trying to count coins, because it adds up...got 400 bucks I could have?

gas is an indispensable good. and it doesnt matter if youre counting and saving up to the coins. i bet you got 400 bucks laying around your house. it could be something useless or some crap you forgot about in the attic.

try paying 4.05 premium. even 4.15 in san francisco told by a friend. just filled up yesterday when the gas light came on- $66

going jet skiing this weekend. my ski also takes premium. i predict it'll be 4.10 by saturday.

haa 4.15...no thanks

I use to have an expedition that took premium...but it had a 28gl tank....i think I would cry if I still had to fill that up right now

i was just thinking, my check engine light has been going on and off for a while. I had a garage plug a computer into it and they said it dind't come up with any codes, yet the light still comes on. could it be because i'm using regular instead of premium?

It's probably a short somewhere - there's a wire that's most likely rubbing and grounding out, no doubt a part of the emmisions system on the truck. I've had three or four wires on the rear driver's side do this over the past year.

You're going to have to wait til it's on all the time to find what it is. Nothing to worry about.
