Gas poll* What type gas do you use?
I only use super in my roadster.
Have 20600 miles with flawless performance.
Made my own windscreen, looks very good.
Its a "hot" car but.....not quite enough room in the driver seat.
I'm 6 feet so, thats average for a guy.
The Porsche Boxster has just a tad more room.
I believe that dollar for dollar, the Xfire is a better buy and....soooo much more unique.

Even though you didn't experience any "problems", that's not to say that the next person who actually "Buys" your old car woun't.
I use to work with a guy who purchased a new car every two years. He said that way he never had any problems to deal with. Oh, and he never changed the oil or the filter on them. (just to save a few bucks) I wouldn't want to get a hold of one of his old rides either.

We have a high compression engine, you can "retard" the timing all you want, it doesn't change the compression ratio. There have been lots of threads about running low octane gas in the Crossfire. I've seen the damage that running "cheap" gasoline can do to a piston over time.
I simply stated it would be nice to know the serial # of your car when you turn it back in, in case another forum member may be concerned about you choosing to use cheap gas in your engine.
I don't owe you an apology for simply commenting that "some" people wouldn't want a car that was run on Low octane fuel. I know I wouldn't, and I'm sure I'm not alone.
By the way, I never said you didn't do other required maintenance to your car, I simply related a story of someone I knew who cut corners to save a buck. If that offended you, it must be because I hit a nerve. Remember, you're the one who said you used cheaper gas.

Guess you and I just have philosophical differences in life.
I use the gasoline that the car requires. In my NA Crossfire I use 87 octane. I have not experienced any pre ignition, detonation or "pinging". MPG and performance meet OE standards. I try to avoid alcohol in gas...I run Shell and Mobil 1 in all my engines...including mowers and motorcycles...

In your last two posts, you've made a pitiful attempt at "name calling" by saying that I have a sheepel mentality, and later infering I'm a snob simply because I choose to use hi-octane fuel in a car that requires hi-octane fuel. (By the book, and under warranty specifications)
All this because I was so out-of-line to point out the fact that (IMO) most people on this forum would prefer to purchase a car that used the "correct" fuel as oppossed to one that had been on a steady diet of "CHEAP" gas for the last 2.5 years.

No worries, just having some fun on the forum....perhaps we'll race one day to resolve the regular v. premium debate, though I doubt it.

I used my car for work yesterday, and put over 350 miles on it. I filled it up to the brim before I started my trip, and again this evening when I filled up. (So I'm sure about exactly how much gasoline I used).
The first part of my trip was Canton to Cleveland, then Cleveland to Pittsburg, all on the Interstates, between 65 and 75 mph. About 25 miles of stop & go city driving in Pittsburg, (sometimes a little heavy on the throttle just to keep from getting run over). On the trip home, I took secondary roads, lots of down and upshifting for the first 1/2 of the trip, and probably averaged 45 mph. But the second 1/2 of the trip home I was moving pretty good, and ran better than 55 or 60 mph (still on 2 lane country roads) with a lot more shifting than I would have been doing on the Interstates.
Then today, 65 miles on mostly 2 lane roads averaging about 50 mph.
The end result, 29.4 mpg.
My car just turned 37k yesterday, completely stock, original air filters, and plugs, and I drive with my window down most of the time, and the AC wasn't on. Oh yeah, my wing is ALWAYS down. No hyper-mileage techniques, and no "Tornado".
I do coast when ever I can, as long as I can stay with the flow of traffic, and I try to stay off the brakes as much as possible. I hardly ever down shift to "slow" down, (brake pads cost so much less than replacing a clutch anyway).
My very good friend usually gets better mileage than I do with his Base Crossfire. But "Base" cars do weigh a little less, but I think it's just because he's a better driver than I am.
I'm not exactly sure what a "Scangauge II" is, but an ordinary "vacuum" gauge will help to teach ya to stay off the throttle.

Maybe my lower mileage is just that I have an automatic transmission. It's the first automatic transmission car I've ever owed in 42 years of driving. My bad knees, made me think, I don't ever want to be sitting in traffic holding down two pedals again. I love the auto, and will continue to try to improve my mileage.

im 19 years old live on my own work and go to school have my own apartment and live in LOS ANGELES so gas price are higher here then any where as far as i know and i use premium using anything else is just going to hurt you in the long term i get 20 mpg and i drive 80 to 85 on the freeway twice a week for 60 miles both ways if i drive 65 ive been able to get 25 mpg its way better then when i had my lifted crew cab silverado and was getting 8 to 12 mpg so buying premium should be an issue just do it its recommended for a reason chrysler/ mercedes did the research hence why they put premium on the gas door to remind you

I was reading in the car manual that non-oxygenated fuels are used in other countries where this same vehicle is sold. I use non-oxygenated fuel just for that fact that ethanol isn't the greatest for any vehicle. I believe it was back in the 70's when Brazil decided to use 40% ethanol and many cars were left dead on the road.
I put 93 in regularly, and he seems to like it, hasn't got drunk on the alcohol yet! In this tank I started a gummout octane booster that is supposed to take it to 103. I Chirped the wheels going into 3rd the other night!
Works for me!
Works for me!
That 103 wouldn't really make a difference unless you turned up your boost on your SRT6 or had a higher compression racing engine. You would otherwise cause possible engine damage.
what about states like GA (where i live) that require all pumps to mix up to 10% ethanol in all their gas blends?? i know my mileage has suffered in my cars living compared to when i travel and fill up in other states without ethanol.
